Samsung 18650 Charger

I have multiples (5) of these which I have purchased over the past 4 or so years. They charge 123/16340 and 18650 Li (I have not used them for LiFePo cells such as the SureFire 123 batteries however) and IMR 123 batteries nicely. I have used these chargers with Fenix (16340), Olight (IMR 16340) and Surfire (18650) batteries and they have worked well. The display is very helpful for getting a sense of where the batteries are in the charging cycle. This charger does not, to my knowledge recondition batteries. Also, there may be calibration differences among charger or even in one charger itself -- individual charger may read cells' voltages differently including reading them differently in the charger's own left and right channels. This has not been any sort of a problem, as far as I can tell, with the cells I have been charging. Another small niggle is that the input cable fits a bit loosely into the charger.

I use this to charge my 18650 batteries. I love the price, how lightweight the charger is, the clear digital readout, and USB capability. Works wonderfully! So glad I ended up purchasing this particular charger after much research.

Package arrived quickly, came with everything needed to get started 18650 battery, 2 bay charger, video cord and all. A little slow on start up, and wish it had auto focus. Other than that, this thing is great. Easy to sight in and operate. multple color pallettes.

I bought the Nitecore charger and 2 Nitecore 18650 batteries for a bug zapper. It had a battery, but I figured it would be good to have spares. Well, surprise, not all 18650 batteries are the same size and Nitecore's 18650 don't fit. So now I'm stuck with 2 useless batteries. Charger works great with the no-name battery.

Excellent charger. So far I have used it for 18650 batteries in protected and unprotected versions, 18350, 16650, and 14500. I have also used it with NiMH chemistries. It can pretty much charge anything I throw at it.

I'm very happy with these 18650 batteries.

Great so far... A little weird behaviour with AAA and AA batteries but perfect with 18650 batteries.

Using it to charge some Nitecore 18650 batteries, so far so good, no problems, and happy with the performance.

One of the best flashlights I've ever owned. Be sure to use with a high-capacity 18650 (3600?) NItecore battery.

The 18650 charged quickly and went into service deep in a cave. Thanks for the quick delivery.
