Hey Josh,
I wouldnt waste my money on a PT with a battery. Buy extra batteries if you're going to go that route. The PT's with battery are horrible and don't even vape as good as a battery, IMO!
OR
Get a PT w/o battery in it and direct vape from usb.
I wasted money 2 times using these cheap battery inline PT's. They are all in the trash now!
You'd be better off buying 2 extra batteries with your 20.00 or go to Puresmoker and get a real PT. Yes a wait, but worth it, OR you could make your own.
