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.

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.
