Anker Power Bank

- 20,000mAh, 87W total, 65W single
- Built-in USB-C cable
- Three-device charging
Our take
A strong all-rounder with a built-in cable and three-device sharing.
Why it made the shortlist
The Anker 20,000mAh bank shares 87W across three devices, with a single device receiving up to 65W, and it has a built-in USB-C cable rated for over 10,000 bends. The cable charges an iPhone 15 Pro to 58 percent or a MacBook Air to 52 percent in 30 minutes.
It suits campers who run a laptop and a phone from the same bank. The 87W total keeps both reasonably fast.
What works
- 65W to one device, 87W shared
- Built-in cable rated for 10,000 bends
- Fills a MacBook Air to 52 percent in 30 minutes
- 20,000mAh covers a weekend
Watch out for
- Single built-in cable
- The catch
- The 65W peak applies to one device, so shared use drops each port's speed.
