Review on 50AA2500 EBL Individual Battery Charging System - Rechargeable Batteries by Aaron Sorensen

Get their charging case when not using a computer's USB3 port. This is perfect, I usually need to charge 6 or 7 at a time (mouse and keyboard are 6 and my watch is 1). My energizers were fully charged in about 6 hours! The batteries that come with it seem to be very good. On for over a month and still at 60% for my peripherals (9-10 hours a day with my Kbps). My other batteries would now be around 30m).
