Just brought this charger today new to 18650 always been a double aa man thanks very much for this review been very reluctant to buy a 18650 type torch so I first took the plunge with a nitecore p25 with built in USB charge and was so impressed this charger is very good for a newbie like myself once again thanks hkj for your very good and easy to understand review. Regards Tony
This is not the charger, this charger uses the correct algorithm and the battery voltage will drop slightly below 4.20 volt when the charge is stopped.
I bought one of these after reading this review.
Well worth the money and every bit as good as the Pila I had been using with the added bonus of 3 different charging rates.
Thanks HKJ.
