Biggest power bank allowed on a plane
Updated 2026-11-06
Short answer. The best biggest power bank allowed on a plane is the AOHi Future Starship 240W ($119; buy: https://dealectric.com/go/aohi-future-starship-240w-27600mah, code 20AUTUMN saves $23.80): 27,600 mAh, 99.36 Wh, 140 W from either USB-C port, and it refills at 140 W. Will it get through security? Yes: it sits under the 100 Wh limit airlines apply to power banks carried without approval, and the Wh rating is printed on the body, which is what screeners look for. It must ride in your carry-on; power banks are never allowed in checked bags. It is also the cheapest of the 99 Wh, 140 W banks: the EcoFlow RAPID Pro has the same capacity and a faster one-hour refill but lists for $175.99 on ecoflow.com (2026-11-06), and the Anker Prime 27,650 mAh is the heavier, app-controlled choice at a higher list price.
If you only charge a phone, tablet or a laptop that tops out at 100 W, you do not need the full 99 Wh. The Baseus EnerFill FC41 ($79.99; buy: https://dealectric.com/go/baseus-enerfill-fc41-25000mah-145w, code FC41 saves $33, pre-applied by the link) gives 25,000 mAh with two built-in cables and about 1.1 lb, and the AOHi Black Warrior ($79.99; buy: https://dealectric.com/go/aohi-black-warrior-25200mah-170w, code 20AUTUMN saves $15.99) gives 25,200 mAh (90.72 Wh) with two 100 W ports and a 100 W refill in about 1.5 hours, both for the same money.
Need more than 100 Wh? The AOHi Starship 40,000 mAh ($179; buy: https://dealectric.com/go/aohi-starship-40000mah-140w, code 20AUTUMN saves $35.80) is 146 Wh, which the rules allow only with airline approval in advance and a limit of two. Ask your carrier in writing before you buy; several refuse power banks over 100 Wh outright.

Rows marked with a code and buy link are products Dealectric lists: the price was verified on the brand's own US store on 2026-11-07 and the code is tested daily in that brand's cart; the date shown is its last pass (last check 2026-11-13). The other rows (Anker, EcoFlow) are included so the comparison is complete; their figures and prices were read from the makers' own US pages on 2026-11-06 and are not re-checked daily. The buy links are affiliate links: they open the brand's official US store at no cost to the shopper, and the commission pays for the testing; see the disclosure.
What owners complain about
Every 99 Wh bank weighs 1.4 to 1.6 lb, and weight is the most common complaint across the AOHi, Anker and EcoFlow reviews we read. Heat is next: ChargerLAB's bench test of the Future Starship 240W held 133 W into a MacBook Pro but tripped temperature protection after 10 minutes at a steady 140 W resistive load, and the front reached 125 °F. EcoFlow's RAPID Pro throttles to 100 W once its cells hit 104 °F. Laptops taper their draw, so neither cuts out in normal use, but do not expect 140 W for an hour straight. Reviewers also note the AOHi display is hard to read in sunlight, and that 99 Wh fills a 16-inch MacBook Pro only about once. On the store side, AOHi's Trustpilot page has just 7 reviews, 5 of them one star, about warranty handling and slow shipping; battery orders are quoted at 10 to 15 business days.
Which one by need
Most battery you can carry on, 140 W laptop: the AOHi Future Starship 240W, for the lowest price in the 99 Wh, 140 W class. Fastest refill between flights: the EcoFlow RAPID Pro, which refills in about an hour on a 140 W charger and in under 30 minutes on its own 320 W charger. Phone and tablet, or a 100 W laptop: the Baseus EnerFill FC41 for built-in cables and the lightest weight, or the AOHi Black Warrior when you want a 100 W refill instead of 65 W. More than one laptop charge per day: the AOHi Starship 40,000 mAh, but only after your airline approves a 146 Wh power bank in writing.
Not recommended
Anything over 160 Wh cannot fly at all. Banks that print only mAh with no Wh rating risk confiscation, because screeners cannot check them against the limit. Buying a 101 to 160 Wh bank without asking the airline first is a gamble: approval is not assured, and several carriers refuse power banks in that band. Finally, skip 90 Wh banks that cost more than the AOHi but refill at 65 W, such as the UGREEN Nexode 25,000 mAh 200W at $129.99 (us.ugreen.com, 2026-11-06), unless you need its particular port mix.
