3.7 Volt Rechargeable Solar Battery Aa Size

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.

I bought this because I purchased a flashlight that will operate on either a AA battery (1.5 volts) or a 14500 battery (3.7 volts) and this battery works very well in this application. It fit in the flashlight just fine and it holds a good charge for a long time. I have only charged it up 2 times since I got it but I am very pleased and I will by again.

Great light does what I want is bright for size of you use 3.7v rechargeable it is pretty bright,. Only complaints is it is not as bright as the hp1 that this flashlight replaced on there market and the red ring on the tail cap so I use a old hp1 cap also doesn't have the anti roll thing so it will roll off a uneven surface

If you’re looking for a replacement for your Ring Solar Pathway Light button type, 18650 3.7V battery, this it.

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.

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.

Much better than the old wireless keyboards. Good feel. Also like that it is rechargeable instead of AA batteries. Overall size is smaller than I thought it would be and hence easier to fit on the desk, even with the numeric keypad

I appreciate that this battery pack came with two ways to use it. To put in AA batteries or to use the rechargeable batteries. Love the thought process in the details as well. Having a shutter button on the battery pack makes up for adding bulk to the camera. Yes this is my first battery pack I have gotten.

-Superb battery life (At 100mw, I get over 8 hours with a pair of rechargeable 2400mh NiMh AA. It will go 14 hours if using lithium AA!) -Excellent sound quality. -Unrivaled reliability. -Smartphone App lets you change settings via dweedle tone. I love the newer, darker finish on them.
