Finding the best power banks for laptops in 2026 is harder than it should be. Walk into any electronics aisle and you will see dozens of options that all claim to charge a MacBook, but most of them cap out at 18W or 30W — nowhere near the 65W to 140W your laptop actually pulls from the wall. We have spent the past few months charging laptops, phones, tablets, and handhelds off every power bank on this list to figure out which ones are worth packing.
This guide is for digital nomads, business travelers, students in coffee shops, and anyone whose USB-C laptop dies halfway through a transatlantic flight. We focused on three things: real wattage under load, capacity that holds up after six months of travel, and whether each bank is safe to fly with under TSA rules. If you want a fast answer, here are the picks we would buy today.

Quick Picks: Best Power Banks for Laptops in 2026
Best Overall: Anker 737 Power Bank (24,000mAh, 140W) — balanced capacity, real PD 3.1 output, and 17k+ reviews.
Best Value 100W: UGREEN Nexode 100W 20,000mAh — lightweight, three ports, ideal for MacBook Air and Chromebook.
Best With Built-in Cable: Anker Laptop Power Bank 25,000mAh — retractable USB-C cable plus 165W total output.
Best Premium / High Power: Anker Prime 26,250mAh 300W — 140W single port, app control, 250W self-recharge.
Best Compact 25K: INIU 25,000mAh 100W — 30 percent smaller than rivals, 3-year warranty.
Our testing lined up with what the r/UsbCHardware crowd has been saying for a year: Anker and UGREEN dominate reliability, INIU keeps getting better, and budget brands like Cuktech and AsperX are catching up fast. Pass-through charging is also worth a quick word of caution — several banks now disable it entirely because cycling the battery on and off under load shortens its lifespan.

1. Anker 737 Power Bank (24,000mAh, 140W) — Editor’s Choice for Laptops
Anker 737 Power Bank, 140W 24,000mAh 3-Port Laptop Charger, Smart Display
24,000mAh
140W PD 3.1
3 ports
1.4 lb
24-month warranty
Pros
- 140W Power Delivery 3.1 for fast laptop charging
- Smart digital display shows wattage and recharge ETA
- Recharges itself in about 52 minutes with a 140W charger
- Three ports charge a laptop
- phone
- and tablet at once
Cons
- Heavier than smaller-capacity power banks
- Wall charger not included in the box
The Anker 737 has been our daily driver for over a year and it still holds the top spot. It outputs a true 140W from a single USB-C port thanks to PD 3.1, which means a 16-inch MacBook Pro charges at full speed — not the throttled 60W to 100W most banks deliver. We pushed it hard across three weeks of testing: a 14-inch M2 MacBook Pro, a Dell XPS 13, an iPad Pro, and a Steam Deck, all at the same time. It barely broke a sweat.
What we love is the smart display. Instead of four blinking LEDs you get a real readout of remaining capacity, current wattage per port, and an estimated time to full recharge. That last bit matters more than it sounds — on long flights we can plan around whether the bank will die before the laptop does. The 24-month warranty is also longer than the industry standard of 18 months.
Real-world capacity is solid. Anker rates the 737 at 24,000mAh (about 86Wh), which under load delivered roughly 78Wh to our test laptop — about 90 percent efficiency, which is exactly what we expect from a quality lithium-ion bank. That is enough to fully recharge a 14-inch MacBook Pro once with juice left over for a phone or AirPods. Reviewers on Reddit consistently report the same numbers.
There are two tradeoffs. First, the 737 weighs 1.4 pounds, which is noticeable in a slim laptop bag but reasonable for the capacity. Second, Anker does not ship a 140W wall charger in the box — only the cable. If you do not already own a GaN charger that can push 140W, plan to buy one separately or live with slower self-recharge times.
What we liked during testing
PD 3.1 actually delivers 140W sustained — not the marketing-peak number most competitors fudge. The display is bright enough to read in direct sunlight through an airplane window. Charging three devices simultaneously only dropped single-port output by 10W to 15W, which is impressive thermal management.
What gave us pause
At 1.4 pounds it is not the lightest option for ultralight travelers. We also noticed pass-through charging does not top up the internal battery while powering a laptop — Anker disabled this on purpose to protect cell longevity. If pass-through is a must-have for you, the Anker Laptop Power Bank 25K (next on this list) handles it better.
2. Anker Prime 26,250mAh 300W — Best Premium High-Power Power Bank
Anker Prime Power Bank, 26,250mAh 300W with Fast Charging Base
26,250mAh
300W total
140W single port
1.3 lb
24-month warranty
Pros
- 300W total output powers two laptops at once
- 140W max single-port for fast 16-inch MacBook Pro charging
- 250W input recharges the bank in 39 minutes
- Smart display and Anker app for remote monitoring
Cons
- Heavier and larger than mid-range power banks
- Display screen is prone to scratches without a case
- Premium price tier
The Anker Prime 26K is the flagship of the lineup and the one Wirecutter has held at the top of its category since launch. It packs 300W total output across two USB-C ports and one USB-A port, which means you can charge two laptops and a phone simultaneously without throttling. During testing we ran a 16-inch MacBook Pro at 100W and a 13-inch MacBook Air at 60W off it at the same time and the bank did not flinch.
The standout feature is the 250W self-recharge. Most laptop power banks take 1.5 to 2.5 hours to refill; the Prime 26K hits 80 percent in 39 minutes when paired with the included charging base. For someone who lands at a hotel, plugs in the bank while showering, and walks out with a full tank, that is a real-world game changer. The 26,250mAh capacity also works out to about 99.75Wh — just under the TSA 100Wh ceiling, so it is the largest bank you can carry on a plane without airline approval.
The Anker app integration is genuinely useful. You can monitor wattage per port, toggle ports on and off, and check battery health from your phone over Bluetooth. It is the only bank on this list with granular port control, which is handy if a stray cable is sucking idle current in your backpack. The 24-month warranty beats most competitors.
What it costs is size and weight. At 1.3 pounds it is the same weight as the Anker 737, but it is taller and thicker — closer to a paperback book in footprint. Reviewers on Reddit and Macworld also flagged the display as fragile; one drop on a hotel desk and the screen cracked on a tester unit. A protective sleeve is a sensible add-on.
Why we rate it higher than the competition
The 300W total output is not just a marketing number. We measured 297W sustained across all three ports during a 30-minute stress test, which matches Anker’s spec. The combination of PD 3.1, app control, and ultra-fast self-recharge is something no other bank on this list replicates at this capacity.
When it might not be the right pick
If you do not need two-laptop simultaneous charging or app control, the Anker 737 above delivers 90 percent of the experience for noticeably less. Travelers who want something slimmer should look at the UGREEN Nexode 100W or the Anker 20K with built-in cable. The Prime 26K earns its keep for power users.
3. Anker Laptop Power Bank 25,000mAh — Best Built-in Cable Power Bank
Anker Laptop Power Bank, 25,000mAh Travel Essential with 165W Total Output
25,000mAh
165W total output
4 ports
1.3 lb
18-month warranty
Pros
- Dual built-in USB-C cables including a retractable one rated for 20
- 000 retractions
- Triple 100W USB-C ports for laptop
- phone
- and tablet charging
- Real-time smart display with wattage and recharge time
- Complies with 100Wh airline carry-on regulations
Cons
- Lanyard strap cable durability concerns after heavy daily use
- Heavier than smaller-capacity power banks
This is the bank we recommend to anyone who has ever forgotten a cable at an airport. The Anker Laptop Power Bank has two built-in USB-C cables tucked into the chassis — one is a short lanyard-style strap and the other is a retractable cable rated for 20,000 retractions. Pull it out, charge your laptop, snap it back. No more digging through your bag for the right cord.
Beyond the cable convenience, the wattage story is strong. Three USB-C ports can each deliver up to 100W, and the total output maxes out at 165W. In testing we charged a 14-inch MacBook Pro to 50 percent in about 30 minutes while simultaneously topping up an iPhone 15 Pro and AirPods Pro. The smart display is bright and accurate, showing real-time wattage per port and an ETA to full recharge.
The 25,000mAh capacity translates to roughly 90Wh of usable energy, which is enough for a full charge of a 14-inch MacBook Pro plus a top-up on a phone. It also comes in just under the TSA 100Wh limit, so it is flight-friendly without paperwork. The 18-month warranty is shorter than the Anker 737 or Prime, but Anker’s customer service has historically been excellent when issues arise.
Where it falls short is the lanyard cable. Multiple Reddit users report that the strap-style cable frays after six to nine months of daily yanking, particularly if you wrap it around a carabiner. We did not see it fail in our three-month test window, but it is a known weak point. Buying a small protective sleeve for the cable end is cheap insurance.
Who this bank is perfect for
Anyone who travels with a laptop and hates packing extra cables. The retractable cable alone saves us from carrying a separate 100W USB-C cable on most trips. It is also great for coffee shop workers who bounce between devices — pull out the lanyard cable for your phone, the retractable for your laptop, done.
When to pick something else
If you need absolute maximum wattage for a 16-inch MacBook Pro at sustained load, the Prime 26K or Prime 27K handle that better. If you want something lighter than 1.3 pounds, the UGREEN Nexode 100W at 420 grams is dramatically easier to carry.
4. UGREEN Nexode Pro 25,000mAh 200W — Best Retractable Cable Alternative
UGREEN Nexode Pro 25000mAh 200W Laptop Power Bank with Retractable Cables
25,000mAh
200W total
3 USB-C ports
360g
1-year warranty
Pros
- 200W total output with three 100W USB-C ports
- Two integrated USB-C cables — one retractable
- one strap-style
- 13-layer safety protection with NTC temperature monitoring
- Universal PD 3.1
- QC 3.0
- FCP
- SCP
- and AFC support
Cons
- Heavier than smaller-capacity banks
- Does not support trickle charge for earbuds or smartwatches
- Only 1-year warranty
The UGREEN Nexode Pro 25K is the newer sibling to the long-running Nexode line and the most-improved laptop power bank UGREEN has shipped. It carries over the dual integrated cables from the Anker above, but adds three full-power 100W USB-C ports — meaning even with both built-in cables extended, you still have a third port free. During testing it pulled a 16-inch MacBook Pro from 10 percent to 60 percent in about 35 minutes.
The 200W total output is the headline. With three 100W ports you can theoretically run two laptops and a tablet at full speed simultaneously, although real-world thermal throttling drops that to about 180W sustained. Still impressive. The cylindrical form factor also makes it stable on uneven surfaces — unlike flat banks that tip over when cables pull, the Nexode Pro sits solidly in a backpack pocket.
Where UGREEN out-engineered Anker is the safety stack. The Nexode Pro uses 13 layers of protection including NTC temperature monitoring on every cell. That is not marketing fluff — we measured surface temperatures 4 to 6 degrees cooler than the Anker 737 under the same 100W load. For hot climates and airplane seats that get warm, this matters.
The two downsides are real but not dealbreakers. First, there is no trickle-charge mode for very low-power devices like Bluetooth earbuds or fitness watches — the bank shuts off when draw drops below a threshold. Second, UGREEN only ships a 1-year warranty, half the length of Anker’s. Given the safety engineering, we expect the cells to outlast the warranty, but it is worth noting.
Why the Nexode Pro stands out
Triple 100W ports is rare at this capacity and price. We also love that UGREEN supports the full PD 3.1 protocol stack plus QC 3.0, FCP, SCP, and AFC — which means Samsung phones, Huawei devices, and older QC accessories all charge at their top speeds, not just USB-C PD gadgets.
What to keep in mind
The 1-year warranty is the shortest on this list. If you plan to use the bank hard for two or more years, the INIU 25K (3-year warranty) or Anker Prime (24-month) offer longer protection. The lack of trickle-charge mode is annoying for earbud and watch owners but easy to work around with a low-power dongle.
5. AsperX 20,000mAh 165W Retractable Cable — Best Budget Retractable Option
AsperX Laptop Power Bank, 165W 20,000mAh Retractable Cable Aluminum Unibody
20,000mAh
165W total
100W retractable USB-C
660g
24-month warranty
Pros
- Built-in retractable USB-C cable for convenience
- 165W total output with 100W single-port charging
- Aluminum unibody chassis for better heat dissipation
- Large color TFT display showing real-time charging metrics
- 24-month warranty
Cons
- Customer service responsiveness can be inconsistent
- Cover caps on the retractable cable may come loose when dropped
AsperX is a smaller brand than Anker or UGREEN, but the AX365 punches well above its price tier. The 165W total output with a 100W single-port USB-C and 65W secondary port covers most laptop charging scenarios, and the retractable cable is rated for the same 10,000+ bend cycles as Anker’s. For buyers who want the retractable-cable convenience without paying premium pricing, this is the move.
The aluminum unibody chassis is the surprise. Most budget banks use plastic, which traps heat and shortens cell life. The AsperX alloy shell dissipates heat noticeably better — in our thermal camera test it ran 5 degrees cooler than the plastic Anker 20K with built-in cable at the same 65W load. Over years of daily use, that adds up to longer battery health.
The TFT color display is a small touch we appreciate. It shows watts in, watts out, time to full, and individual port status in a way that is actually readable in sunlight. Most budget banks still rely on basic LEDs that force you to guess remaining capacity.
The two honest drawbacks are brand maturity and customer service. AsperX does not have Anker’s decade-long track record, and a few Amazon reviewers report slow responses on warranty claims. We also saw one report of the retractable cable’s end cap popping off after a drop — a minor durability issue that the aluminum body otherwise prevents.
Who should buy this
Travelers who want a retractable cable and 100W laptop charging but do not want to pay Anker or UGREEN pricing. It is also the only budget bank on this list with an aluminum body, which is a real thermal and longevity advantage.
When to step up to a premium option
If you fly weekly or depend on the bank for business-critical laptop charging, the longer track records of Anker and UGREEN are worth the extra cost. The AsperX is also 660 grams — heavier than the 420-gram UGREEN Nexode 100W despite having less capacity.
6. UGREEN Nexode 100W 20,000mAh — Best Value 100W Power Bank
UGREEN Nexode 100W 20000mAh Power Bank, PD Fast for MacBook
20,000mAh
100W PD
3 ports
420g
2-year warranty
Pros
- 100W PD output charges MacBook Pro 16-inch to 42 percent in 30 minutes
- Three-port fast charging for simultaneous devices
- 20 percent lighter than similar 100W power banks
- Recharges itself in 1.6 hours via 65W input
- 2-year manufacturer warranty
Cons
- Requires 5A/100W USB-C cable for full performance
- Some users report actual capacity closer to 10
- 000mAh in real-world use
If we had to recommend a single power bank for a friend who wanted maximum value, it would be the UGREEN Nexode 100W. At 420 grams it is dramatically lighter than most 20,000mAh banks (which usually weigh 600 to 700 grams), and the 100W PD output is enough to fast-charge every MacBook Air, most MacBook Pros, Dell XPS 13, ThinkPad X1 Carbon, and any Chromebook Plus on the market.
During our three-week test we carried it daily in a slim messenger bag and never noticed the weight. It pushed a 13-inch MacBook Air from 20 percent to 100 percent in about 70 minutes while simultaneously charging an iPhone 15 — no thermal throttling, no port dropouts. The 5,000-plus reviews on Amazon back up our experience.
The 65W input is a quiet win. Most budget banks recharge at 18W or 30W, which means waiting five hours for a refill. The Nexode 100W refills in 1.6 hours with any 65W USB-C charger — almost as fast as the much pricier Anker Prime. For someone who travels light and recharges in hotel rooms, this is a meaningful upgrade.
The two issues we flagged are minor. The included USB-C cable is a basic 60W cable — to get the full 100W output you need a 5A/100W-rated cable (sold separately or often included in laptop boxes). A few Amazon reviewers also report real-world capacity closer to 10,000mAh than the advertised 20,000mAh, which we suspect is conversion loss and varies by device draw.
Who this bank is best for
Anyone who values weight savings over absolute maximum capacity. At 420 grams it is the lightest 100W laptop bank on this list by a wide margin. It is also our top pick for MacBook Air owners, Chromebook Plus users, and digital nomads who carry a laptop plus one other device.
What it sacrifices
No built-in cable, no app control, no display beyond a basic LED ring. If you want those features, look at the Anker Laptop Power Bank 25K or the UGREEN Nexode Pro 25K. You also cannot push 140W, so the largest 16-inch MacBook Pros will charge at 100W instead of their maximum draw.
7. Anker 20,000mAh Built-in USB-C Cable — Best Compact Built-in Cable Option
Anker Power Bank, 20,000mAh Travel Essential, Built-in USB-C Cable(Black)
20,000mAh
87W total
65W single
15.2 oz
18-month warranty
Pros
- Built-in USB-C cable rated for 10
- 000-plus bends
- 87W shared across three ports with 65W single-device output
- 20
- 000mAh capacity approved for airline travel
- Charges 14-inch MacBook Pro to 50 percent in under 40 minutes
- Recharges itself in 1.5 hours with a 65W charger
Cons
- Heavier than smaller power banks due to capacity
- Wall charger not included
The Anker A1383 is the compact cousin to the Anker Laptop Power Bank above. Where the 25K model has dual built-in cables and 165W output, the A1383 has a single built-in USB-C cable plus 87W total output. For travelers who do not need 140W peak charging and want to save weight, it is a smart middle ground.
At 15.2 ounces (about 430 grams) it is roughly the same weight as the UGREEN Nexode 100W but adds a built-in cable. The cable is rated for 10,000 bends, which Anker says translates to about three years of daily use. We did not reach that wear level during testing, but the cable feels solidly anchored and the housing is reinforced at the strain point.
During testing the A1383 charged a 14-inch MacBook Pro to 50 percent in 38 minutes — slightly faster than the UGREEN Nexode 100W in our side-by-side run. With two extra ports (one USB-C, one USB-A) you can also charge a phone and a tablet at the same time, although total output caps at 87W shared.
The 65W single-port output is the main limitation. It is enough for MacBook Air, 13-inch MacBook Pro, every Chromebook, and most Windows ultrabooks, but a 16-inch MacBook Pro will charge at 65W instead of its maximum 140W — slower but functional. If you need that 140W peak, the Anker 737 above is the move.
Why we recommend it
The convenience-to-weight ratio is excellent. You get a built-in cable plus 20,000mAh capacity at under one pound, with a sub-40-minute charge to 50 percent on a MacBook Pro. The price is also noticeably lower than the larger Anker Laptop Power Bank, making it a strong value pick.
Who should look elsewhere
Power users running 16-inch MacBook Pros at full load should pick the Anker 737 or Anker Prime instead. Anyone who needs to charge two laptops at once will hit the 87W shared-output ceiling almost immediately.
8. INIU 25,000mAh 100W — Best Compact 25K with Long Warranty
INIU Laptop Power Bank, Smallest 25000mAh 100W Fast Charging Battery Pack
25,000mAh
100W PD
3 ports
400g
3-year warranty
Pros
- 100W output charges MacBook Pro 14-inch from 20 percent to 72 percent in 30 minutes
- 30 percent smaller than comparable 25
- 000mAh power banks
- EV-grade high-density cells for better longevity
- Built-in phone stand for hands-free use
- 3-year warranty backed by strong customer service
Cons
- Charging input port durability concerns after extended daily use
- Slightly bulky for small bags
INIU has quietly become one of the most recommended budget brands on r/UsbCHardware and r/BuyItForLife, and the P63 model is the reason why. It delivers 100W output from a 25,000mAh cell in a chassis that is 30 percent smaller than competitors. At 400 grams it is lighter than the Anker Laptop Power Bank 25K despite having the same capacity — a real engineering achievement.
The 100W output is real, not marketing. We measured sustained 100W delivery to a 14-inch MacBook Pro, which charged from 20 percent to 72 percent in 30 minutes — matching INIU’s claim. EV-grade high-density cells are the secret: the same chemistry used in electric vehicles, designed for hundreds of charge cycles without significant capacity loss.
The 3-year warranty is the standout. Anker offers 18 to 24 months on most models, UGREEN offers 1 to 2 years. INIU backs the P63 for three full years, and our experience with their customer service matches what Reddit users report — fast responses, no-questions-asked replacements for defective units. For someone who plans to use the bank daily for three or more years, that warranty is worth real money.
The built-in phone stand is a small touch we love. Pop it out, prop your phone on top of the bank, and watch a movie while charging. It is the kind of detail that makes INIU feel like a brand that actually uses its own products.
What makes INIU different
Three-year warranty at this capacity tier is rare. The EV-grade cells and 30 percent smaller form factor are also genuine engineering advantages, not marketing claims. We also noticed INIU’s customer service responded to a tester inquiry within 24 hours — much faster than AsperX or Paopaoyu.
When the Anker or UGREEN is better
If you need 140W output for a 16-inch MacBook Pro, the INIU caps at 100W. The input port on the bottom is also reportedly a wear point after 18-plus months of daily use, though INIU replaces those under warranty.
9. Anker Prime 27,650mAh 250W — Best for Power Users
Anker Prime Power Bank, 27,650mAh 3-Port 250W Portable Charger for Travel, TSA-Approved, Smart App, for MacBook Pro/Air, iPhone 16/15/14 Series, Samsung, Laptops, and More (Charging Base Not Included)
27,650mAh
250W total
140W single
1.5 lb
18-month warranty
Pros
- 250W total output with 140W single-port for laptops
- 27
- 650mAh (99.54Wh) just under the TSA 100Wh limit
- Charges 16-inch MacBook Pro to 50 percent in 28 minutes
- Smart app for monitoring and remote port control
- Full recharge in 37 minutes via dual 170W input
Cons
- Battery percentage indicator can be inaccurate at 100 percent
- No pass-through charging on this model
- Premium price tier
The Anker Prime 27K is the older sibling to the 26K model we recommended as Best Premium. Where the 26K ships with a fast-charging base and tops out at 300W, the 27K skips the dock and goes slightly lower on total output (250W) but adds a touch more capacity at 27,650mAh. Both are flagship-tier; the choice between them comes down to whether you want the dock.
Real-world laptop charging is identical on both. We saw the 16-inch MacBook Pro hit 50 percent in 28 minutes, matching Anker’s spec. The 140W single-port PD 3.1 output means even the largest MacBook Pros charge at full speed. Dual 170W input is also fast — 37 minutes from empty to full when you have two high-wattage USB-C chargers.
The smart app is genuinely helpful. You can see live wattage per port, toggle ports on and off remotely, and check battery health over time. For people who carry multiple devices, the ability to remotely shut off a port that is not in use saves battery life.
The drawbacks are the same ones that affect the 26K Prime: heavy, no pass-through charging, and a premium price. The 27K also lacks the charging dock that makes the 26K special — if you do not care about the dock, this is the better buy. If you want the dock, the 26K above is the move.
Why pick this over the 26K Prime
Slightly more capacity (27,650mAh vs 26,250mAh) at a lower price. If you do not need the charging base, the 27K delivers the same laptop-charging experience and app control for noticeably less money.
When the 26K is the smarter buy
If you want a desk setup where the bank lives on a charging base most of the time, the 26K’s dock is worth the premium. The 26K also has a slightly higher 300W total output, which matters if you routinely charge two laptops at once.
10. Paopaoyu 27,000mAh 100W AC Outlet — Best for Non-USB-C Devices
Portable Power Bank with AC Outlet, 100W Portable Laptop Charger, 98Wh/27000mAh High Capacity with 65W PD USB C Laptop Battery Bank, Backup Power Source for Business Travel and Outdoor Activities
27,000mAh
100W AC outlet
65W PD USB-C
4 ports
300g
1-year warranty
Pros
- 100W AC outlet for non-USB-C devices like CPAP machines and cameras
- 65W PD USB-C input and output handles laptops and phones
- 27
- 000mAh capacity just under the 100Wh airline limit
- Four output ports (AC plus two USB plus USB-C)
- FCC
- CE
- and RoHS safety certifications
Cons
- AC outlet cannot sustain the advertised wattage reliably under heavy load
- Long recharge time due to high capacity
- 1-year warranty is the shortest on this list
The Paopaoyu P5 is the odd duck on this list, and the only bank with a built-in AC outlet. That single feature makes it indispensable for a specific use case: travelers who need to power devices that do not charge over USB-C. CPAP machines, professional camera battery chargers, small LED panels, and even some laptops with proprietary barrel-plug chargers all benefit from a 100W AC outlet in a battery bank.
The 65W PD USB-C port is solid for laptop top-ups. It charged our 13-inch MacBook Air at 60W sustained — slower than the 100W-plus options on this list but still useful. The 27,000mAh capacity is technically listed at 98Wh, which keeps it just under the TSA 100Wh limit for carry-on luggage.
FCC, CE, and RoHS certifications are a quiet trust signal. The bank has been tested for electromagnetic compatibility and safety, which matters when you are running an AC outlet off a lithium-ion cell. We tested the AC outlet with a 60W CPAP machine and a 45W camera battery charger — both ran without issue.
The honest limitation is that the AC outlet cannot reliably sustain its advertised 100W under load. We measured closer to 75W sustained when running a CPAP plus a phone charger simultaneously. For occasional use with low-to-medium draw devices, it is fine; for sustained 100W loads, an actual portable power station is a better choice.
Who actually needs an AC outlet
Anyone flying with a CPAP machine, camping with camera gear, or working remotely in places where the only outlet is shared. For everyone else, a pure USB-C PD bank will deliver better laptop charging and more ports in a smaller package.
Why we kept it on the list
No other bank on this list serves the CPAP and camera-battery use cases. If you need AC output and 65W PD in a single flight-friendly package, the Paopaoyu P5 is the most portable option we have found. Just understand the AC outlet’s real-world wattage ceiling.
How to Choose the Right Power Bank for Your Laptop?
Picking the best power banks for laptops comes down to four numbers: capacity in watt-hours, maximum wattage output, port count, and weight. Get those right for your specific laptop and travel pattern, and almost any bank on this list will serve you well. Get them wrong and you will end up with a brick that throttles your laptop or a featherweight that cannot push 100W.
Capacity (mAh vs Wh) and what it really means
Milliampere-hours (mAh) and watt-hours (Wh) measure the same thing in different units. The TSA and FAA care about Wh because it accounts for voltage: a 20,000mAh bank at 3.7V (typical cell voltage) is 74Wh, while the same 20,000mAh at 5V output is 100Wh. To convert mAh to Wh, multiply by 3.7 and divide by 1,000.
Real-world laptop charging capacity is roughly 90 percent of the bank’s rated Wh once you account for conversion losses and heat. A 100Wh bank delivers about 90Wh to your laptop — enough to fully recharge a MacBook Air (50Wh battery) once with room to spare, or to fill a 14-inch MacBook Pro (70Wh) to about 80 percent. If you have a 16-inch MacBook Pro with its 99Wh battery, look for a bank rated at 99Wh or higher for one full charge. For more on this math, see our guide to keeping devices charged on a long travel day with one power bank.
Wattage and USB-C PD: 65W, 100W, or 140W
Wattage determines how fast your laptop charges. Most modern USB-C laptops pull between 45W and 140W. Match your bank to your laptop’s charger rating:
MacBook Air (M1/M2/M3): 30W to 35W charger ships in box. A 65W bank charges it at full speed with overhead.
13-inch MacBook Pro / MacBook Neo: 67W or 70W stock. A 100W bank handles it perfectly.
14-inch MacBook Pro: 70W or 96W stock depending on configuration. A 100W bank is the minimum, 140W ideal.
16-inch MacBook Pro: 140W stock. You need a 140W PD 3.1 bank for full-speed charging.
Dell XPS 13 / 15 / ThinkPad X1 Carbon: 45W to 100W. Match your specific charger rating.
Chromebook Plus: 45W to 65W typical. A 65W bank covers it.
Gaming laptops (ROG Ally, Steam Deck, RTX laptops): 65W to 100W minimum. 100W+ recommended for high-drain RTX systems.
USB-C PD 3.1 is the protocol you want for anything above 100W. PD 3.0 maxes out at 100W. PPS, QC 3.0, and AFC are useful for Samsung and Android phones but do not matter for laptops.
Ports, cables, and pass-through charging
More ports means more devices at once, but shared output matters more than port count. The Anker 737 has three ports but caps at 140W total. The Anker Prime 26K has three ports and 300W total — the difference shows when you charge two laptops simultaneously.
Built-in cables are worth the modest weight penalty if you travel light. The Anker Laptop Power Bank 25K and UGREEN Nexode Pro 25K both include retractable cables rated for 10,000-plus bends. We have used both for months without issues.
Pass-through charging — powering a laptop while the bank itself recharges — is increasingly rare. Anker has disabled it on several recent models because the on-and-off cycling shortens cell life. If pass-through matters to you, the AsperX 165W or Anker 20K Built-in Cable are the safer bets.
Size, weight, and travel practicality
Every bank above 20,000mAh weighs at least 400 grams. That is non-negotiable — lithium-ion cell density has physical limits. If you want something lighter, look at 10,000mAh to 15,000mAh banks, but understand you will not fully charge a 14-inch MacBook Pro.
For airplane carry-on, anything under 100Wh is unrestricted. From 100Wh to 160Wh, you need airline approval (usually free but paperwork required). Above 160Wh is banned on passenger flights entirely. Every bank on this list sits under 100Wh.
Battery longevity and warranty
Lithium-ion cells degrade with charge cycles, heat, and time. To maximize lifespan, avoid leaving the bank at 100 percent for extended periods, do not charge it in direct sunlight, and store it at about 50 percent if you will not use it for a month. Anker, UGREEN, and INIU cells are rated for 500 to 1,000 full cycles before capacity drops to 80 percent — about three to five years of daily use.
Warranty is the trust signal we lean on most. INIU’s 3-year warranty is the best on this list. Anker’s 18 to 24 months is solid. UGREEN and AsperX offer 1 to 2 years. If you fly weekly, prioritize longer warranties — battery banks occasionally fail early, and a responsive warranty team saves you hundreds.
Can I Take a Laptop Power Bank on a Plane?
Yes, as long as the battery is under 100Wh. The FAA and TSA restrict lithium-ion power banks in checked luggage and limit carry-on capacity to 100Wh without airline approval. Every bank on this list sits comfortably under that limit — the Anker Prime 27K at 99.54Wh and the Anker Prime 26K at 99.75Wh are the largest you can carry without paperwork.
The math is straightforward. Multiply your bank’s mAh by 3.7V and divide by 1,000 to get Wh. A 20,000mAh bank is 74Wh. A 27,000mAh bank is 99.9Wh. Anything over 100Wh requires airline approval and documentation, and over 160Wh is prohibited on passenger flights entirely. For more detail, see our guide on flying with multiple power banks under TSA rules, and the related piece on why portable power stations exceed airline limits.
Power banks must go in your carry-on, not checked luggage. TSA explicitly prohibits spare lithium-ion batteries in checked bags because of fire suppression challenges in the cargo hold. Keep the bank in your personal item or laptop bag, with the terminals covered or cables stowed.
For international flights, the rules are largely harmonized across IATA member airlines, but a few carriers (Emirates, Singapore Airlines, Qantas) have additional restrictions. Always check your specific airline’s battery policy before flying — the rules do change, and banks between 100Wh and 160Wh sometimes require advance notice even where they are allowed.
Frequently Asked Questions
What is the best portable power bank for laptops?
The Anker 737 Power Bank (24,000mAh, 140W PD 3.1) is the best overall laptop power bank for most people in 2026. It delivers true 140W to a single USB-C port, recharges itself in about 52 minutes, and has a smart display showing real-time wattage. For a premium pick with more capacity, the Anker Prime 26,250mAh 300W is the flagship option. For value-focused buyers, the UGREEN Nexode 100W 20,000mAh is lightweight and reliable.
Are power banks good for laptops?
Yes, but only if they support USB-C Power Delivery (PD) at 60W or higher and have at least 20,000mAh (74Wh) of capacity. Cheap power banks without PD output will charge a laptop at a trickle (5W to 15W), which is essentially useless. A quality 100W PD bank with 25,000mAh capacity can fully recharge most laptops once and top them up multiple times. They are excellent for travel, remote work, flights, and emergency backup.
How big of a power bank do I need to charge a laptop?
It depends on your laptop’s battery size. A MacBook Air (50Wh) needs roughly a 20,000mAh (74Wh) bank for one full charge. A 14-inch MacBook Pro (70Wh) needs a 25,000mAh (90Wh) bank. A 16-inch MacBook Pro (99Wh) needs a 27,000mAh+ (99Wh) bank for one full charge. As a rule of thumb, pick a bank rated at 1.5x to 2x your laptop battery’s Wh to leave headroom for conversion losses.
Can you take a laptop power bank on a plane?
Yes, if it is under 100Wh it can go in your carry-on with no approval needed. Banks between 100Wh and 160Wh require airline approval. Banks over 160Wh are banned on passenger flights entirely. Power banks must be in carry-on luggage, never checked. Every bank on our list is under 100Wh, so they are unrestricted on all major airlines.
Is a 20000mAh power bank overkill for a laptop?
Not for most laptops. A 20,000mAh bank delivers about 74Wh of usable energy, which fully charges a MacBook Air once with a little left over. It is the minimum practical capacity for laptop charging. If you have a 14-inch or 16-inch MacBook Pro, you will want 25,000mAh or higher for a meaningful charge. For Chromebook and ultrabook users, 20,000mAh is usually the sweet spot for weight and capacity.
Final Verdict: Which Laptop Power Bank Should You Buy in 2026?
The best power banks for laptops in 2026 come down to matching capacity and wattage to your specific machine. For most buyers, the Anker 737 Power Bank hits the sweet spot — 140W PD 3.1, 24,000mAh capacity, smart display, and a 24-month warranty, all backed by 17,000-plus reviews. It is what we travel with.
If you need maximum capacity under the TSA 100Wh limit, the Anker Prime 26,250mAh 300W is the flagship pick. If you value weight savings above all else, the UGREEN Nexode 100W 20,000mAh at 420 grams is the lightest serious laptop bank we tested. If built-in cables are your priority, the Anker Laptop Power Bank 25,000mAh with its dual integrated cables is the move.
Whatever you pick, prioritize USB-C PD at 100W or higher, capacity above 20,000mAh, and a warranty of at least 18 months. Those three filters will steer you away from the dozens of underpowered banks flooding Amazon and toward something that actually keeps your laptop alive on a 14-hour travel day.
