Review on POWOBEST High-Speed LCD Charger & 3 x 2600mAh Rechargeable 🔌 Battery Bundle for Xbox Series X/S & One Controllers - Accessories Kit by Paul Gravely

First of all, I'm a "self-proclaimed battery technician" with a degree in chemical engineering. The batteries were just a pack of AA shrink wrap. My goal with any new battery is a full 24 hour charge (sometimes 48 hours). The base charger does not behave as if it has a complex charge control protocol. The batteries felt cool from noon until the next morning, but at the end of the 24-hour rated charge, the batteries felt quite warm. I will not buy this charger again. Full disclosure, this was a gift purchase for my 'little gamer' so I have no long term experience with it. However, there is evidence that this is an old-school charger that will fry your batteries instead of charging them properly.
