Compatible with: 510-thread oil cartridges (pre-filled and refillable).

Description

The Wulf Uni 3.0 Universal Variable Voltage Battery is built for cartridge users who want a reliable daily device that travels better than a standard pen battery. The box-style body is the first big advantage because it helps protect your cartridge inside the frame, which makes it more pocket-friendly and less likely to get knocked around.

Inside, the Uni 3.0 runs a 650mAh internal battery that’s strong enough for regular daily use without making the device bulky. Voltage is adjustable from 1.8V to 4.2V, so you can keep things smooth and flavor-forward at lower settings, then dial up the heat for thicker vapor when you want a stronger pull.

Fit is another major reason people choose the Uni style. The adjustable cartridge height helps you dial in how your cart sits inside the device, improving compatibility and keeping everything looking clean and secure. Charging is handled through USB-C, which makes it easy to top up with the same cable you probably already use for other devices.

If you’re tired of exposed carts, inconsistent hits, or pen batteries that feel flimsy in the pocket, the Wulf Uni 3.0 is a solid daily carry option that gives you protection, adjustability, and a clean setup.

The Uni 3.0 is built for real daily carry, protecting your cartridge while giving you full voltage control for smoother, more consistent hits.
