Top complaints
INIU Pocket Rocket P50 (Carry P50-E1)
- Slow or stop-start charging
Low-star Walmart reviews describe charging that is very slow, charging that keeps starting and stopping even with a new cable, and a unit that didn't work at all. Tom's Guide's con is lower charging power than its other picks.
- Less than a full phone charge for some
A 1-star Walmart reviewer says it doesn't charge a phone even once.
Source: Walmart reviews (lowest rated) - No built-in cable
It comes with a short detachable USB-C cable instead of a built-in one (Wirecutter). A Walmart reviewer needed a different cord to charge their phone.
Anker Nano Power Bank (10K, 30W, Built-In USB-C Cable)
- Inconsistent charging and early failures
Amazon's review summary says some owners see inconsistent charging and premature failure after a few months. A 1-star Walmart reviewer says it kept getting hotter on a flight while the screen went blank, and it had to be handed to a flight attendant.
- 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.
- Mixed value for money
Amazon's summary says some owners find it well worth the money while others say it isn't worth the price.
