the coolest battery EVER

look at this battery i just bought!!!!! its a pen and a vape pen! and it actually writes too… im obsessed. i love having whimsical accessories and my regular 510 battery has felt sooo boring and default so im super glad to have this!

it says it has multiple voltage settings (between 1.8 and 3.8) but ive never own a battery with those options before. does anyone have any recommendations of what voltage is best? i tend to use carts semi-lightly, like ill hit it a few times and then be done, rather than hitting it all day if that matters. it also says i can do an 8-second preheat cycle, is that a good thing to do?

yayyy the pen pen 🖊️
