Anker 10,000mAh 30W USB-C Power Bank
Our verdict
The attached USB-C cable is the entire point here, rated for ten thousand bends and short enough to stay out of the way, so the battery is never useless because you left a cord at home. Thirty watts in both directions refills a large phone to about half in under half an hour and tops the bank itself up overnight.
- 10,000mAh capacity
- 30W bidirectional charging
- Built-in USB-C cable
- Three charging ports
Why we picked it
Ten thousand milliamp hours in a body roughly the size of a deck of cards is the format most people should buy: about two full phone charges, light enough to forget in a jacket, and comfortably within airline rules. Two further ports sit alongside the attached cable, so earbuds or a watch can share the same trip.
Compared with INIU's detachable-cable approach, Anker's cord is fixed, which is neater day to day but a single point of failure over the years. What you get in return is an eighteen month warranty and Anker's long track record on charging safety, which counts for a lot in a category full of anonymous brands.
Best for
- People who forget their cables
- Day trips and commutes
- Topping up phones and earbuds
Keep in mind
- The built-in cable cannot be replaced, so the life of the bank is tied to it.
- Some owners report noticeable capacity loss after a year or so of daily use.
- Older iPhones with Lightning ports need their own cable plugged into a spare port.
