Outstanding piece of gear
September 14, 2014
I have several 18650 Li-Ion batteries that were given to me by a flashlight manufacturer along with four chargers also given to me by the same manufacturer. Over a period of time, none of the chargers would charge to batteries, so I didn't know if it was a case of bad batteries, bad chargers, or both. After reading all of the reviews, I chose the Fenix. It was a great choice, as I was able to bring all of my 18650's back from the dead (except for one, plus all of my NiMh EverReady and Duracell AAA's that also stopped accepting charging from the (store bought) chargers that came with the batteries.
Bottom line, the chargers that are usually supplied as part of a blister pack with 4 AA's or 4AAA's or even 2 18650's ARE ALL JUNK. Buy this charger and throw the others away. Beats trying to replace all of your batteries!
Pros:Individual monitoring / charging for each of the 4 bays. You can put in any combination of AAA, AA, or 18650 and this charger will monitor each battery's capacity and give you a visual bar graph of each battery's progress.
Cons:Haven't found any yet.
