The best power bank for laptop travel clears two bars. Its USB-C port matches your laptop charger’s watts, and its rating stays under 100 Wh so it boards the plane with you. That second bar got stricter this year. Since 27 March 2026, ICAO rules cap you at two power banks in the cabin. IATA also says airline approval for 100 to 160 Wh power banks ends with its 1 January 2027 rules, so anything bigger is a bad buy for a flyer.
You get six picks for a big laptop, a travel router running Tailscale or WireGuard, a Raspberry Pi 5 and a mini PC, plus how to read PD wattage and PPS. None of these banks went through our lab; capacity figures come from independent discharge tests. We checked specs against maker pages, prices through Amazon’s API and airline rules against IATA, FAA and airline notices in October 2026.
Pick a laptop power bank at a glance
Every bank on this list rates under 100 Wh, so all six fit the no-approval cabin tier. Two of them (the Anker 737 and the INIU) don’t print the Wh figure on their maker pages, so read the label on the bank itself. What separates them is how many watts one USB-C port can deliver and what else you need to run from it:
- Best overall for a 16-inch laptop: Anker Prime 26K 300W (A110A). Two USB-C ports at 140 W each, 99.75 Wh, and a display that shows watts per port. Check the price on Amazon.
- Best value for two laptops: EcoFlow RAPID Pro 27,650mAh 300W. Two 140 W ports, one of them a built-in retractable cable, at 99.54 Wh. Check the price on Amazon.
- Best for a USB-C mini PC: Anker 737 (PowerCore 24K, A1289). 140 W from one USB-C port (70 W each when two share it), with independently measured capacity. Check the price on Amazon.
- Best budget 140 W: UGREEN Nexode 25000mAh 145W. A 140 W port for well under $100, with a slow 65 W refill. Check the price on Amazon.
- Best for a travel router and phone: INIU 20000mAh 65W (P62-E1). Small, 324 g, with PPS listed and enough for a 13-inch ultrabook. Check the price on Amazon.
- Best for 12 V barrel-jack gear: Talentcell PB030201-35. A 12 V DC output next to a 45 W USB-C port, at 76.65 Wh. Check the price on Amazon.
If your 13 or 14-inch laptop ships with a 65 W charger, you do not need a 140 W bank. The INIU covers it at about half the weight of the big Ankers, and the money you save buys a better travel router.
See how we picked
We started from what a laptop, a router and a mini PC ask a USB-C port for. Then we pulled the Amazon US catalog through the Creators API on 27 October 2026. A bank made the list only if it passed all of these:
- Its capacity works out under 100 Wh, from the maker’s Wh figure or from its mAh rating where the maker prints only that, so it boards without airline approval.
- You get at least one USB-C port that matches a common laptop charger: 65 W, 100 W or 140 W.
- You can buy it new from Amazon US today, and the listing matches the model on the maker page.
- You aren’t buying a model named in a 2025 or 2026 power bank recall that our search of recall news turned up.
We did not bench these banks ourselves, so every capacity number below names its source. TechRadar measured the Anker 737 with a ChargerLAB POWER-Z meter, and techtest.org ran discharge tests on the Anker Prime 26K and the 737.
Two popular banks missed the cut. We could not confirm the Baseus Blade 100W’s Wh rating or weight on a Baseus page. The CUKTECH 20 rates well at techtest.org, but its maker page would not load for us.
Compare the power bank specs side by side
The Wh column is the one that matters at the airport, and the single-port column is the one that matters to your laptop. Prices are Amazon US on 27 October 2026 and they move every week:
| Power bank | Printed rating | Best single USB-C port | PPS | Recharge input | Weight | Price |
|---|---|---|---|---|---|---|
| Anker Prime 26K 300W | 26,250 mAh, 99.75 Wh | 140 W (28 V 5 A), on both C ports | Not listed by Anker; measured by techtest.org | 140 W per port, 250 W with both | 600 g | about $200 |
| EcoFlow RAPID Pro 27,650mAh | 27,650 mAh, 99.54 Wh | 140 W, on two of four C outputs | Not listed | 280 W | 699 g | about $110 on sale ($176 list) |
| Anker 737 (24K) | 24,000 mAh, 86.4 Wh (per TechRadar) | 140 W (28 V 5 A) | Measured by techtest.org | 140 W (28 V 5 A) | about 630 g | about $110 |
| UGREEN Nexode 25000mAh 145W | 25,000 mAh, 90 Wh | 140 W on C1, 65 W on C2 | No | 65 W | 513 g | about $80 |
| INIU 20000mAh 65W | 20,000 mAh, Wh not printed online | 65 W (20 V 3.25 A) | Listed, range unpublished | 45 W | 324 g | about $42 |
| Talentcell PB030201-35 | 76.65 Wh | 45 W, plus 12 V DC out | Not listed | 12.6 V barrel charger | Not published | about $50 |
The first two rows show why mAh is the wrong number to shop by. The EcoFlow lists 1,400 mAh more than the Anker Prime, yet the Anker prints the higher Wh figure. The arithmetic implies Anker counts its cells at about 3.8 V and EcoFlow at about 3.6 V. Wh is what a bank stores and what airline staff read off the label, so compare that column and ignore the mAh race.
The “300W” and “145W” in the product names are totals across every port. They are not what one laptop gets.
Get the Anker Prime 26K 300W for a 16-inch laptop
This is the bank to buy if your laptop came with a 140 W USB-C charger and you want it to charge from the bank at the same speed. Both USB-C ports do 140 W at 28 V and 5 A, so you can plug a big laptop into either one without checking which port is the fast one.
Who it suits: you travel with a 16-inch laptop, often carry a second device that wants fast charging too, and you’d rather read the watts on a screen than guess. Look elsewhere if you mostly charge a 65 W ultrabook, because you’d be carrying 600 g and paying about $200 for headroom you never use.
Anker rates the A110A at 26,250 mAh and 99.75 Wh, just under the 100 Wh cabin line. It has two USB-C ports at up to 140 W each, a 22.5 W USB-A port and a 300 W combined ceiling. It refills at 140 W through one port or 250 W through both.
Expert Reviews ran 140 W, 140 W and 20 W at once. techtest.org found it held 140 W steadily and treated 300 W as a short peak that throttles back. It measured 79.6 to 89.8 Wh delivered, about 80 to 90 percent of the label. That is a normal loss for boosting cell voltage up to 20 or 28 V.
The one gap is PPS. Anker’s own pages do not list it for the A110A, although techtest.org’s unit offered PPS from 4.5 to 21 V at up to 5 A. That test is encouraging if your phone needs PPS, but it is not a spec Anker promises.
A 240 W cable and a 24-month warranty come with it. The bundle with a charging base costs about $80 more, and you don’t need the base. It sells for about $200, so check the live price before you buy.
Save with the EcoFlow RAPID Pro for two laptops
The EcoFlow RAPID Pro matches the Anker Prime on the numbers that count: two 140 W outputs and a rating just under 100 Wh. On 27 October 2026 it sold for about $90 less. If you charge two laptops at once, it’s the better buy at that price.
Buy it if you share a bank between two laptops, or you lose cables and want one that can’t be left behind. Look elsewhere if weight matters most. At 699 g it is the heaviest bank here, and a built-in cable is one more part that wears out.
EcoFlow lists 27,650 mAh, a 140 W single-port maximum and a 300 W multi-port total. Macworld gave it an Editors’ Choice and lists 99.54 Wh. Its two 140 W PD 3.1 outputs include a 60 cm retractable cable, and two 65 W USB-C ports sit beside them. Macworld confirmed both 140 W outputs work at the same time.
The bank refills at up to 280 W over USB-C. EcoFlow’s 320 W figure needs its own desktop charger or pogo-pin dock, so plan on the USB-C number.
A “RAPID Pro X” listing at about $190 is a different product we did not verify, so make sure your cart holds the 27,650mAh 300W model. It sells for about $110 on sale against a $176 list price, so check the live price before you buy.
Run a USB-C mini PC on the Anker 737
The Anker 737 is the bank we’d hand a mini PC or a 140 W laptop when one device gets all the power. It has been on sale since 2022, and that is the point. More than one reviewer has measured its capacity, and the numbers agree.
It fits you when you run one hungry device at a time, like a USB-C mini PC with no outlet nearby, and you want known runtime numbers. Look elsewhere if you need two fast ports. The 737 splits to 70 W and 70 W once a second USB-C device plugs in.
The 737 has two USB-C ports and one USB-A, a 140 W ceiling at 28 V and 5 A, and a 140 W recharge input. TechRadar lists it at 86.4 Wh. It measured 77.1 Wh delivered at 20 V and 5 A (89 percent), and 73.1 Wh at 28 V. techtest.org’s 2026 unit averaged 74.63 Wh across its loads and offered PPS from 4.5 to 21 V.
Pass-through charging runs up to 90 W. TechRadar notes the bank does not refill itself while doing it and has no UPS mode, so do not use it as backup for a mini PC that must never drop power. A power station or a real UPS does that job.
Anker’s pages disagree on weight (607 g and 630 g), and techtest.org weighed 641 g, so plan on about 630 g. Early 2022 units had a 28 V problem with the Framework Laptop 16, which techtest.org did not see on its 2026 unit. It sells for about $110, so check the live price before you buy.
Spend less with the UGREEN Nexode 145W
This UGREEN gets you a 140 W USB-C port for about $80, the cheapest route to full-speed charging on a 140 W laptop in this guide. The savings come out of the refill speed and the second port.
Good match: you want one big laptop charged fast on a budget, and you can top the bank up overnight. Look elsewhere if you refill between flights or your phone needs PPS. This bank lists neither a fast refill nor PPS.
UGREEN’s spec table for SKU 90597A lists 25,000 mAh at 3.6 V (90 Wh). You get 140 W on C1, 65 W on C2 and 22.5 W on USB-A, with 145 W as the combined total. Only C1 accepts input, and only at 65 W. That is less than half the Ankers’ refill speed, so a bank you drain on the plane takes far longer to fill at the hotel. The protocol list covers PD 3.0 and QC 3.0 but not PPS, and it weighs 513 g.
The Amazon title does not print UGREEN’s model number. PCWorld links this same listing to the 145W bank with 140 W from one port, but some retailers list a different port split, so check the 145W label and the port markings when it arrives. It sells for about $80, so check the live price before you buy.
Pack the INIU 65W for a travel router and phone
A travel router does not need a 140 W bank. GL.iNet rates the Beryl AX at under 8 W and the Beryl 7 at under 12 W. The INIU’s 65 W port has room for the router, your phone and a 13-inch ultrabook, and at 324 g it weighs about half as much as the 140 W banks.
Made for you if you carry a travel router, a phone and maybe a small laptop, and you want the lightest bank that still charges a laptop. Look elsewhere if your laptop shipped with a 100 W or 140 W charger. Under load it will charge slowly or not at all from a 65 W port.
INIU’s page for the P62-E1 lists 65 W on the first USB-C port (20 V at 3.25 A), 36 W on the second and 18 W on USB-A, with 60 W total. Input is 45 W, PPS is among the protocols, and a 100 W cable and a three-year warranty come with it. Both USB-C ports together drop to 45 W and 20 W, which still leaves the router plenty.
INIU does not publish the PPS voltage range or the Wh rating online, so read the Wh figure printed on the bank before you fly with it. The Amazon title also lacks the model number. The name, capacity and weight are what tie it to the P62-E1.
INIU did recall a power bank in December 2025, but it was the BI-B41, not this model. It sells for about $42, so check the live price before you buy.
Feed 12 V barrel-jack gear from the Talentcell
Some gear never got a USB-C input. Cellular routers built for a van and 12 V network switches take a 5.5 mm barrel plug. The Talentcell feeds them 12 V directly instead of through an adapter cable.
Right for you if you run a 12 V device, such as the GL.iNet Spitz Plus that our travel router guide lists with a 9 to 36 V input. Look elsewhere if your mini PC uses a 19 V or 20 V barrel jack, which most do. This bank only outputs 12 V on its DC side.
Talentcell’s page for the PB030201-35 lists 76.65 Wh, a 45 W USB-C PD port, an 18 W USB-A port and a DC5521 one-to-two splitter, and it links to this exact Amazon listing. It recharges from its own 12.6 V barrel charger rather than over USB-C.
The page lists that charger at 1 A while the Amazon title says 2 A. Its technical details tab is an image with no text, so we could not confirm the maximum 12 V output current. Check your device’s input current against the label before you rely on it. It sells for about $50, so check the live price before you buy.
Work out runtime for a router, Pi or mini PC
You can estimate runtime from two numbers: what the bank delivers and what the device draws. Use about 75 Wh for the Anker 737 and about 80 Wh for the Anker Prime 26K, the low end of each measured range. For the device, the maker’s maximum rating gives you a worst case:
| Device | Power input | Draw used | Anker 737 (75 Wh) | Anker Prime 26K (80 Wh) |
|---|---|---|---|---|
| GL.iNet Brume 2 (GL-MT2500A) | 5 V 2 A | under 2.6 W (max) | about 29 h | about 31 h |
| GL.iNet Beryl AX (GL-MT3000) | 5 V 3 A | under 8 W (max) | about 9 h | about 10 h |
| GL.iNet Beryl 7 (GL-MT3600BE) | 5 V 3 A, 9 V 3 A, 12 V 2.5 A | under 12 W (max, no USB load) | about 6 h | about 6.5 h |
| GL.iNet Slate 7 (GL-BE3600) | 5 V 3 A, 9 V 3 A, 12 V 2.5 A | under 18 W (max, no USB load) | about 4 h | about 4.5 h |
| Raspberry Pi 5, idle | 5 V 5 A recommended | about 3 W | about 25 h | about 27 h |
| Intel N150 mini PC with USB-C power input, idle | USB-C PD (most use a barrel jack) | 7 to 11 W | about 7 to 11 h | about 7 to 11 h |
Read the router hours as a floor, because GL.iNet’s figures are maximum draw and a router moving light traffic sits well below them. The two low-draw rows are the least certain: the 75 and 80 Wh figures were measured at 20 to 28 V, and some banks switch their output off when a 2 to 3 W load looks like nothing is plugged in.
The Pi 5 and N150 idle figures come from our Raspberry Pi 5 vs N150 comparison, and they rise fast under load.
Say you run a GL.iNet Tailscale setup on a Beryl 7 through a long travel day. INIU publishes no Wh figure, but 20,000 mAh at a typical 3.6 to 3.7 V cell voltage is about 72 to 74 Wh, and at 80 to 85 percent delivery that’s roughly five hours at full draw. Treat that as our estimate.
Power a Raspberry Pi 5 or mini PC over USB-C
A Raspberry Pi 5 boots from any power bank that gives 5 V at 3 A, but it won’t get its full USB power budget. The Raspberry Pi documentation recommends 5 V at 5 A (25 W). On a supply that can’t offer 5 A, the Pi limits its USB ports to 600 mA in total, against 1.6 A on a 5 A supply.
Laptop power banks reach their higher watts by raising the voltage, not by offering 5 A at 5 V. None of the banks here lists the 5.1 V 5 A profile the Pi 5 needs for its full budget. The official 27 W Pi supply does it with a 5.1 V at 5 A profile.
That 600 mA limit is fine for a headless Pi with an SD card. It bites when you hang a USB SSD off it. The docs describe usb_max_current_enable=1 in config.txt and the Pi 5 EEPROM setting PSU_MAX_CURRENT, which lift the limit. They are meant for supplies that can really deliver the current, so do not use them to push a 3 A bank past its rating. If your Pi needs USB storage on battery, power the drive separately. Our Raspberry Pi 5 kits guide covers the official supply.
Mini PCs are harder, because most still use a barrel jack. ASUS lists a 19 V DC input on the NUC 15 Pro, for example. Minisforum’s UM790 Pro page lists a 19 V adapter and says its USB4 ports support PD power delivery. Before you buy a bank for a mini PC, check these:
- Your mini PC’s spec page says a USB-C port accepts power input, not only that it outputs power.
- The bank’s single-port rating is at least what the mini PC’s own adapter supplies, usually 65 W or more.
- You’ve read the barrel input voltage if you plan to use a USB-C trigger cable, because common PD steps are 5, 9, 12, 15 and 20 V with no 19 V step.
- You’ve confirmed with the maker that a 20 V feed is inside the input range of a 19 V box before you plug one in.
The trigger cable route works on paper, but no maker we checked documents a 19 V mini PC on a 20 V feed. Treat it as your own risk. A USB-C powered mini PC on a 140 W bank is the cleaner setup, and our homelab mini PC guide covers the boxes worth running.
Read PD wattage and PPS on the spec sheet
USB Power Delivery tops out at 100 W (20 V at 5 A) in its standard range. PD 3.1 added 28 V for 140 W, 36 V for 180 W and 48 V for 240 W, according to the USB-IF charger page. Every 140 W port in this guide uses the 28 V step. It only works when the laptop asks for it and the cable can carry it. A spec sheet worth trusting answers these lines:
- You can find the single-port maximum, written as volts and amps (28 V 5 A), not only the total across ports.
- You can see what each port drops to when two devices share the bank.
- You know whether PPS is listed and over what voltage range, if your phone uses it.
- You know the recharge input wattage, which decides how fast the bank refills between flights.
- You can read a Wh rating, not only mAh.
The cable is the part that trips people up. Anything over 3 A needs an e-marked 5 A cable, and 140 W needs one rated for the extended range, sold as 240 W. Plug a 60 W cable into a 140 W bank and your laptop quietly charges at 60 W.
PPS, the programmable mode, lets a phone ask for voltage in small steps instead of fixed ones. Anker lists it as 3.3 to 21 V at 5 A on its Prime 27,650mAh 250W model. It matters for phones, not laptops, so do not pay extra for it unless your phone’s fast mode depends on it.
Learn the 2026 airline rules for power banks
Every regulator agrees on the basics. Power banks travel in the cabin, never in checked bags, and under 100 Wh needs no approval. The FAA PackSafe page still allows two spares of 101 to 160 Wh with airline approval, but IATA’s 2026 guidance puts power banks in their own class. Most of what changed since 2025 is about using the bank on board:
| Rule maker | In force | What it means for you |
|---|---|---|
| ICAO / IATA | 27 March 2026 | Two power banks per person, cabin only, no recharging them on board; using one to charge a device is discouraged. 100 to 160 Wh power banks lose the approval route in the IATA DGR from 1 January 2027. |
| FAA / TSA (US) | Current | Carry-on only, 100 Wh limit, two spares of 101 to 160 Wh with airline approval. |
| Southwest Airlines | 20 April 2026 (visible-use rule since 2025) | One power bank, 100 Wh max, not in the overhead bin, no recharging from seat power, visible while in use. |
| Emirates | 1 October 2025 | No use on board at all; one bank under 100 Wh; not in the overhead bin. |
| Qantas and Jetstar | 15 December 2025 | No use or charging, including from seat power; two banks of up to 160 Wh each. |
| Virgin Australia | 1 December 2025 | No use and no recharging from aircraft power; two banks. |
| Singapore Airlines and Scoot | In force by October 2026 | No use and no charging on board. |
| China CAAC (domestic flights) | 28 June 2025 | Banks without a valid 3C mark, with an unclear label, or under recall are refused at security. |
For your buying decision, a 99 Wh bank is the biggest you should buy. The 100 to 160 Wh tier is shrinking, and Emirates already allows only one bank under 100 Wh. On many long-haul carriers you can no longer charge a laptop from a bank mid-flight, so seat power does that job and the bank covers the layover and the hotel.
The IATA guidance PDF has the full table. Your airline’s own page wins over all of this.
Check these before you board
Most airport trouble with a power bank comes down to a label nobody can read or a rule you didn’t know your airline had. Run through this list the night before you fly:
- You can read the Wh rating printed on the bank itself, and it’s under 100 Wh.
- You’re carrying no more than two power banks, or one on Emirates and Southwest.
- Your bank is in your carry-on and your checked bag holds none.
- You’ve checked your airline’s page for an in-flight use ban and an overhead bin rule.
- Your bank shows a 3C mark if you’re flying within China.
- You’ve packed a 240 W rated USB-C cable if your laptop charges at 140 W.
- You’ve charged the bank at home, since recharging it on board isn’t allowed under the 2026 rules.
If your model is not one of the six above, the same list still tells you whether it can fly. The Wh line matters most, because a bank with a worn or missing label can be refused even when it is well under the limit. Clear tape over the label keeps it readable after a year in a bag. For the home end of the kit, the Brume 2 WireGuard gateway is a 2.6 W box your travel router dials back into.
