Wanted a 2nd battery as backup just in case for my Fitorch P25 which is small and super bright.

It may have other uses, but I use my 26350 in my P25 Little Fatty flashlight.
It provides lots of power to the BRIGHT pocket light, and it's a protected battery to avoid overcharging. Best of all, it recharges using a typical cell-phone charging cord, which plugs in to the battery. It's orange/red when it's charging, and green when it's charged. I wish all my flashlights and batteries were this easy to use.

Perfect little high power battery that has an usb-c port on the battery for charging. Works great with my 3000 lumen little stubby.

Very interesting little battery however I own 3 of these now and since I have no use for them I have to find a use for them so that issue got solved really quick, I being a flashaholic decide I just have to buy another flashlight that I can use these batteries for. Having the Fitorch P25 I instead use it with a ext.tube I bought with it and I only use the 26650, so now I have to buy the new flashlight coming out which is the Acebeam E10 and im sure that these 3 batteries will do just fine with it. These batteries do have good runtime and the voltage is right where it should be when being read on my volt meter and they do charge rather quickly.

Long lasting and easy to recharge due to USB input. Can't go wrong!
