So, this is the only charger I will buy. I tried one of the newer (Nitecore NEW i4) and would assume that the (Nitecore NEW i2 would be the same) chargers but they did not charge the battery completely, this was also mentioned by other people on the net so I sent the i4 back. These Nitecore UM20 USB Chargers are quality chargers and I do highly recommend them.. Not mentioned in descriptions anywhere is the fact that these chargers also can accomadate and charge the dual 20700 batteries which are larger than the 18650.. These are what I use.. Last for years with no issues.

I bought this thinking it would be good but it wasn't. Unfortunately within 10 mins of use the screen on one half blacked out and then eventually came back to normal but one charging bank stopped working. I have the same branded charger but the i4 which is much better. Just spend a little more and get that as I've had it for years without any issue.

This is probably the best charger I have had since I started vaping. It keeps the batteries evenly charged and you can also plug your phone in whilst charging 2 batteries. I would highly recommend this charger for to anyone
