Anker Prime Power Bank, 27,650mAh 250W
The power bank that charges your laptop and still flies carry-on
Anker's Prime Power Bank (A1340) holds 27,650mAh, or 99.54Wh, and puts out up to 250W across three ports, with up to 140W to a single laptop. It recharges in about 37 minutes with 170W dual input and weighs about 1.5 lb.
Our take
Most big power banks are a trap at the airport. Go over 100Wh and you need airline approval, or it gets taken off you at security. This one sits at 99.54Wh, just under the line, and it still pushes up to 140W into a laptop.
That matters if you work on the road. A dead laptop on a long-haul flight, in a train station or on a layover is a lost work day. This charges a laptop and your phone at the same time from three ports. It also refills in about 37 minutes if you have two chargers, so a short hotel stop is enough. The catch is weight. At about 1.5 lb it's a real chunk of your carry-on.
If you carry a laptop and need it working, this is the one we'd buy. Phone-only travelers should get something smaller. Check the price before you book.
Who it’s for
Business travelers and remote workers who need to charge a laptop on long flights, layovers and train days.
Skip it if
Skip it if you only charge a phone and earbuds. A small 10,000mAh bank is lighter and does the job.
