not recommended, buy something better
After under 6 months of use, both the USB ports burned out while using them and charging AA batteries at the same time. Luckily my devices weren't damaged. I contacted support, they said I'm using it wrong, which sure enough, there's a little blip on here about how it can't handle charging regular rechargeable batteries and USB devices simultaneously. No mention of that on the warnings on the product itself, or some sort of mechanism to make sure it doesn't overload itself (like maybe a simple FUSE?). Overall seems like a cheap product. 1 Star, not recommended, buy something better.
