Vape Battery

Excellent battery
Last quiet a long time

My desk drawer was full of 510 batteries that would no longer charge (I must have thought they’d recover). I am so pleased with the Jinx Fatboy. It works great and delivers far more than any of my old batteries. I probably shouldn’t use it on the max setting all the time but I like the big hits.

I recieved the more rounded short one. I prefer the slender longer one. I thought that is what I ordered.

My favorite battery ever!

While charging, the green light on the USB adapter comes on, but the light on the end of the battery blinks red and doesn't quit. When I unplug the battery and fit the cartridge into it, it works but very weak.
Is there a right and wrong battery??
