⚡ AOLIKES 2A Fast Charging Board with USB Charging Protection, 5V 2000mA Lithium Battery Management Module by AOLIKES Review

After trying this Step Down Large Capacity Efficiency product, I can confidently say it is a game changer for any automotive shop. The 2A connectors are powerful and work seamlessly with my equipment. The compact design allows for easy storage in my garage while still providing enough power for all my tools. The only downside is the price point, but the quality and efficiency make it worth the investment.

Charger worked fine. It had connections to many common battery terminals (2-pin, 3-pin, larger 2-pin, and JST universal adapters) and was small enough to incorporate into your own project. In my particular case, I was trying to charge my spare 3 pin headset batteries. The charger plugged into a regular micro USB port and worked without any issues. A small caveat is that I couldn't be 100% sure how the charge level indicator works. It would be nice to have some more guides.

This device is only suitable for charging batteries. Three connectors are for different types of battery connectors. I was hoping for a regulating output to keep the board on battery power and use a USB cable for charging while in use. It doesn't seem to support this scenario. Overall it performs as expected and has great power delivery for large batteries. The indicator glows blue while charging and turns red when complete. I would have expected it to be the other way around, but it works.
