Review on 🔌 Efficient Charging Solution: Grinder PWRCore Lithium Battery Charger by Loren Jacobson

The first to arrive cost nothing. Found that the charger is defective. Revain's help tried to be helpful, but I had to repeatedly explain what the problem was. They confirmed it was defective and promptly sent replacements. The replacement works fine. A bit heavy and clunky, but actually it works very well. Insert a grinding wheel and expect it to run continuously for about 7 minutes before the battery dies. It seemed like full power was about 30 seconds before stopping. Might wait a few seconds and reboot a bit, tried a few times before it reloaded. He ran again, this time with a metal cutting disk. Worked with frequent start-stops within 30 minutes working time. However, it's hard to tell how much of that time was actually "on." Certainly more than 7 minutes, although I believe 15 minutes. Overall, the performance is good and the battery life is decent for the low price. I like the screw in the handle that has 3 possible positions and holds the wrench. The shield has a handy cam lever for easy adjustment. To be honest, the rating should be 4.5 stars, but the first flaw is a serious concern.
