Fantastic All-In-One Charging Solution

Based on my observations this is the best all-in-one charging solution for any garage or shop... It has a sleek design, adjustable voltage output, and is very easy to use. The LED display is also a nice touch that shows the current charging status. However, the only downside is that it can be a bit pricey compared to other charging solutions in the market..

Pros
  • Sleek design, adjustable voltage output, LED display
Cons
  • Pricey compared to other alternatives.

😅 ehhh Not impressed

Works but very fiddly. The charging indicator turns on and off and needs to be connected "properly", it works normally for a while and then suddenly stops charging. I'm not sure if it's just a bad module. I will connect it to a different power source and it will suddenly start working again and then eventually stop, it could be a bad connection because it turns on and off when I plug in the USB port, but sometimes it turns on with no indication of Reasons random. . Not very reliable at all, and

Pros
  • Can be used for a multimeter, converted to charge a lithium battery.
Cons
  • Repair
