Top complaints
- Inconsistent charging and early failures

- Less capacity for its size than rivals
Wirecutter dismissed the A1259 because comparable power banks offer more capacity for the size or price. Anker lists it at 7.58 oz. A Walmart reviewer says it charged their phone only once.

Amazon's summary says some owners find it well worth the money while others say it isn't worth the price.
