3.7 Volt Lithium Polymer Battery Charger

I couldn't find the 3.7 volt version when buying the charger, batteries and tactical flashlight so I mistakenly assumed (I know, I know...)it would charge the 3.7 volt batteries, too. It doesn't now I must buy the 3.7 volt version and am stuck with 2 ea. of the 3 volt batteries w/charger that I don't want or need. but it does charge quick and stays charged, too.

This little flashlight packs a punch. The secret is in the 3.7 volt/ 2.4Wh 16340 with built in USB micro rechargeable port (on the battery). That battery gives this little flashlight a powerful long lasting bright beam. I'm glad that I purchased two of them. I keep one in my toolbox and the other in my car. Highly recommended.

Eartec Rechargeable 3.7V Lithium-Ion Battery for UltraLITE & HUB Systems

I've this flashlight for almost 4 years now and use it on the job pretty much every day. The 3.7 volt Li-Ion rechargeable battery is just starting to go but still works. It so convenient just to plug into a usb a charger.

With the current restrictions on shipping lithium polymer batteries, AC adapters are sorely needed for studio assignments that have larger numbers of photos that need to be people.

The battery charger that came with my Canon Rebel was 110-Volt only. On a Smoky Mountain vacation, my installed battery went dead and there was simply no place to charge it. This charger allows you to charge the battery by way of the cigarette lighter. No more will a dead battery stop me from my photography and I thank the B&H people for leading me to this alternative battery charger

This lithium battery is very reliable.

This charger not only does 110 but has a 12 volt adapter included.

The Watson NP-BX1 Lithium-Ion Battery Pack and Charger Kit is perfect as a second backup battery. The charger has an easy to see charge indicator light !

worked just like the product I replaced except uses a double A battery instead of a nine volt.
