The Quad 510 Thread Square Pen Battery by Ooze is a simple battery like you’re used to: a single on/off button doubles as a temp toggle to cycle through four heat settings, improving the expression of a cart.

Though temp control is pretty common these days, the Quad is different in its square shape, keeping your cartridge out of harm’s way. It’s a small difference, but if you’ve ever lost a brand new cart to a roll-and-fall, the Quad might be looking pretty good right about now.

Additionally, the smart charger extends battery life, solving a common issue with cheap pens that burn out after a few weeks due to overcharging.
