## Customer Reviews

### ⭐⭐⭐⭐⭐ Battery works as intended for Raspberry Pi
*by M***R on August 24, 2024*

Works for a Raspberry Pi 5 great. Last a few hours running multiple websites and constant running. Would recommend.

### ⭐⭐⭐⭐⭐ The battery arived as promised.
*by W***K on January 22, 2024*

This battery was a replacement for a solar charging unit that I use i a car. The old one 'expired' and grew fatter. Time will tell how well the new one will take and hold charge.

### ⭐⭐⭐⭐ Specs exactly as described, don't forget safety though
*by K***W on June 22, 2025*

Bought these to power 700 LEDs in a pair of pants. Lasts about 35 minutes running a light show (which is what we calculated so that's fine). Main thing to be mindful of is that this has no type of covering at all, so we had an issue where we didn't build an enclosure for it and it got scratched and started smoking, so we had to safely dispose of it. Safety first! Make sure you have a suitable enclosure!
