Top complaints
Anker Prime Power Bank (26K, 300W)
- Very expensive
Wirecutter calls it one of the most expensive models it tested. Engadget's only con is the price, especially with the optional $110 charging base (over $300 combined). Amazon's review summary says opinions on value are mixed, and some owners find it expensive.
- Charging base problems
Amazon's summary says battery-life feedback is mixed, and some owners report the charging base dying within months. Wirecutter tried the separately sold base and recommends a USB-C wall adapter instead, because the power bank stands upright on the base and can easily topple over.
- No wall charger in the box
Wirecutter notes you have to supply your own USB-C adapter, ideally one that supports 140 W, to get the full recharge speed.

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.
