Review: Great value - Works surprisingly well for a cheap little power supply. Cool display, simple, not a lot of features but worth the price
Review: Works as expected. - I only needed it to fix my Ryobi 40v batteries. I got an simpler one that broke almost instantly when tried to use. This was was robust. It has safety mechanism to shit off in case of problems. Current supply is stead and sharp, I measured with a multimeter. Very intuitive to use. My house is 110V and worked well. Volt adjustment was simple to use, one knobs for fast move and one for fine tuning. It was a good value. I may start buying all broken Ryobi batteries to fix them and resell 😂

### ⭐⭐⭐⭐⭐ Made My Life Easier
*by A***R on May 24, 2025*

This Power supply works great! I use it to simulate 12v power to manually retract electric parking brakes makes my brake jobs 100x easier only used it 4 times but it’s becoming one of my favorite tools! the quality of the buttons and dials are also very nice and sturdy. I love the voltage adjustability because some cars require 14-15v to activate park brakes. 10/10
