Twist voltage control — stepless
A dial at the bottom sets voltage continuously. Low voltage for flavor, high for clouds. More precise than 3-step systems and adaptable to different cartridge types.
650 mAh — more endurance than mini mods
650 mAh delivers 200 to 400 draws per charge. USB charging. Height-adjustable cartridge holder fits various cartridge lengths.
Who is it for?
510 cartridge users who want stepless voltage control and more battery than mini mods. Not for dry herb. Universal cartridge holder with height adjustment.
Twist Dial Voltage Control
The defining feature of the Yocan Uni Twist is its bottom-mounted twist dial for voltage adjustment. Rather than fixed presets, the dial moves continuously from 2.0 to 4.0 volts. Thin oils with high terpene content work best around 2.4 V, while thicker distillates perform better at 3.2 to 3.6 V. The analog control gives tactile feedback — you can feel the position without looking at a screen. This makes quick adjustments between sessions straightforward and reduces the risk of burning delicate oils.
Cartridge Compatibility
The Uni Twist uses a height-adjustable magnetic adapter that fits 510-thread cartridges from 11 to 16 mm in diameter. This covers slim distillate carts as well as wider ceramic-core options. The magnetic connection protects the 510 threading from wear over time. Swapping cartridges takes seconds without any tools. The 650 mAh battery lasts two to three days with moderate use, and a full charge through Micro-USB takes roughly 45 minutes.
Twist Dial Precision and Cartridge Tips
The twist dial at the bottom of the Yocan Uni Twist controls voltage continuously between 2.0 and 4.2 volts. This precise adjustment makes the device more versatile than models with fixed levels. For thin distillate cartridges, 2.0 to 2.5 volts is enough — higher voltage would burn the flavor. Thicker oil cartridges need 3.0 to 3.5 volts for adequate vapor. Ceramic coils work best at 2.5 to 3.0 volts since they heat more evenly than cotton-wound coils. The adjustable top section accepts cartridges from 10 to 14 millimeters in diameter and centers them in the housing. A quick twist of the voltage dial before the first draw with a new cartridge helps find the right setting without wasting material.
