Review: Nice little charger with good info display. - This charger does a good job with status displays for each battery. Simple to use, just insert battery and it does the rest. Button switches display info if desired. Though I bought this for18650 and 21700 lithium batteries, it does a lot of other sizes too (see listing) . It comes with a USB to USB-C cable and has plug inputs for those sizes as well as micro-USB also. A handy little charger for sure.

### ⭐⭐⭐⭐⭐ Good quality with an informative display
*by J***Z on November 30, 2025*

Works as intended. The screen is really cool and informative Highly recommend this charger. The metal tabs that hold the battery in place are solid too, it doesn’t look like it will break. Charge speed is as fast as the charger brick and wire you use. I use a 65w brick and a 160w wire. So it charges pretty fast.
