Review on Power Up with Panasonic K-KJ75KHC4BA Advanced Battery Charger: Includes USB Charging Port & 4AA Eneloop Pro High Capacity Rechargeable Batteries by Karen Montanez

Better capacity than the old NiCad batteries I grew up with but they were only like that on my Xbox controller. Sometimes they worked fine but other times the Xbox said they had a charge but the controller died mid-game. I ended up buying an Xbox Elite controller, so I don't use it for gaming anymore. Good for other electronics (torches, etc.). It's good to have some batteries charged and ready to go in case of power outages like we just had in Texas.
