Awesome gear from NITECORE 5Stars

Has worked very well for most batteries. AAA require a bit fiddling to achieve the very precise placement needed to have them recognised (and charged) by the charger

Excellent upgrade from my previous 10+yr old model. Works very well.

This is a great product and happy to see it with a USB C connector. I have the older versions with micro USB and they are good but Micro USB is a bit flimsy. Great service and support as well from Nite Core as usual.
