Description

The Rokin Pillar is a 400mAh digital 510 battery built for oil cartridges, with a screen that shows voltage, battery life and a draw timer — information most pen batteries leave you guessing at. Voltage is adjustable from 2.0V to 4.2V in 0.1V steps, so you can dial in a cart rather than cycling through three preset colors.

Why it stands out

• Digital screen with voltage, battery life and draw timer
• Variable voltage 2.0V–4.2V in 0.1V increments
• 15-second preheat at 1.8V for thick or cold oil
• USB-C charging and Rokin’s Powerwave output
• Backed by a 1-year battery warranty
