Excellent charger Review by Leon
Rating
I really like this charger as it can charge different sizes of battery at the same time. I use mine mainly for 4 x Li-ion batteries. The charger according to Nitecore is built of fireproof material so a good option for use with Li-ions although I hope its never put to the test.
Once plugged in via the micro USB port the charger needs no setting up, it just does its own thing which is good. The 18W limitation assists in maintaining charge current which in turn reduces the risk of over heating as Li-ions can get hot if charged at high current, I have no problem erring on the side of caution.
There is a clear display which shows each slot in turn and can be selected with the left hand button - so for each slot you can see battery charge current, voltage and mA/hr charged. Theres also a Good / Poor / Bad based on internal cell resistance and this has shown up a few elederly Ni-MH batteries.
Its worth a mention the Nitecore UMS4 will also charge the larger C & D type 1.5v rechargeables, but you can only fit two at a time due to size.
Overall an excellent charger from Nitecore and I'd buy it again for sure. (Posted on 01-02-21)
