Right out the box the pulsar battery was perfect it has 4 different temp settings making it very easy to use and it packs a punch when you hit it only thing I would say change is go to a usb c charger and make it a lil longer if you don’t mind and it would be the best battery on the market for less than 20 bones

Does what it needs to do and looks cool doing it very small and convenient does everything the other ones do just have the price

very nice saves energy and lasts super long would recommend

Pulsar Mobi 510 Battery | 650mAh

I have had many 5/10 Batteries. We charged this one from the box, never did anything. I put a cartage on it, press the button, preheat light comes on for a flash and that's it. I threw mine out in the recycling and didn't bother with it anymore. P.O.S.
