USB powered with a charging current of 750mA.
Compatible with lithium batteries with a rated voltage between 3.6V and 3.7V. NiMH batteries.
Charging for dummies. There is no need for matching the polarities, as the charger can automatically recognize them when in use.
All sizes compatible. It works perfectly on cylinder shaped batteries of variable diameters and lengths.
Tangle-free flat cable design. Easy for storing and organizing.

*To prevent a short circuit, DO NOT charge batteries with a positive AND negative polarity on the same side. This includes Olight customized batteries built for magnetic charging.

This is a great product! I use it to charge my 18650's and other various batteries and it does the trick. It is super compact as well.

#1 super compact. It's only slightly more bulk than a USB cable. #2 it charges (as far as I know) any Li-Ion or NiMh battery I use. I'm sure there's SOMETHING it doesn't charge, but it charges even the less common battery sizes I'm aware of. #3 Pretty inexpensive. No frills at all. 0. Not even one. But, it works. It's a charger you can take pretty much everywhere, it will charge pretty much whatever you have, it doesn't cost much. Even if you don't use this for 'the' charger you use, it would still be a good option for a go bag/camping kit/traveling. The only faults I see: It's basically just a cable, so it's susceptible to all the things a cable would be. The ends don't really hang on the battery super great. That's really not a concern if you have something to set it on that won't be disturbed. If you have a rambunctious dog or kid that will bump the table, you might have to re-seat the cable on the battery. Those are pretty minor issues though. I've got a couple of decent chargers, but the one that uses only a USB plug for power can't charge NiMh batteries. This one can.
