Our verdict
Where it wins
- Anker rates a single USB-C port at up to 65W, enough to charge most USB-C laptops
- Built-in USB-C cable plus two more ports lets it charge three devices at once
- 20,000 mAh is about 74 Wh, so it still clears the 100 Wh carry-on limit most airlines apply
Where it loses
- Heavy for a pocket at a listed 431 g, closer to a bag item
- A single device tops out at 65W, the 87W figure is the combined total across ports
- USB-A port peaks at 22.5W per Anker's published spec, well below the USB-C outputs
This is the travel pick: enough capacity for several phone charges or a laptop top-up, and the 65W single-port rating covers most USB-C laptops. At a listed 431 g it lives in a bag, not a pocket. Skip it if you only ever charge a phone, a 10K bank is half the weight and much cheaper.

Common questions
Can it charge a laptop?
Anker rates the USB-C outputs at up to 65W for a single device, which matches the charging spec of most USB-C laptops. The 87W number is the combined maximum when several devices are plugged in.
Is it allowed in carry-on luggage?
Yes. 20,000 mAh works out to roughly 74 Wh at the nominal 3.7 V cell voltage, under the 100 Wh limit most airlines apply. It must travel in carry-on, not checked bags.
How many ports does it have?
Three outputs: the built-in USB-C cable, one USB-C port, and one USB-A port. The built-in cable also recharges the bank itself.
