### ⭐⭐⭐⭐⭐ Great E battery charger !!!
*by B***Y on October 2, 2025*

Charges well and quickly. The box doesn’t get hot and the plug and power box store neatly in the packing. I followed the instructions and disconnected it from the battery once the green light appeared. My battery is holding its charge well and I’m very satisfied.
