The Yocan Uni 3.0 from Yocan is a compact 510 battery mod for cartridges. Weighing just 69 g with a 650 mAh battery, it fits in any pocket. Variable voltage covers the range for common 510 cartridges, with max temperature at 230 °C.
In the price comparison, the Uni 3.0 is available across 5 shops -- an affordable, universal cartridge mod.
Universal 510 Mod for All Cartridges
True to its name, the Uni 3.0 is universally compatible with 510 cartridges of all common sizes. An adjustable holder accommodates narrow and wide carts without adapters.
Variable voltage is adjustable steplessly. Lower voltage for thin distillates, higher for thick oils. An OLED display shows the current setting.
Compared to the older Uni Pro, the 3.0 version offers a slimmer design with improved holder. The core function stays the same.
Compact and Light: 69 Grams
At 69 g, the Uni 3.0 is among the lightest 510 mods available. The compact housing disappears in a pocket or bag.
Despite its small size, build quality is solid. The zinc alloy body has a matte finish that resists fingerprints.
The adjustable cartridge holder protects the cart from breakage -- an advantage over open 510 batteries where the cartridge is exposed.
Battery and Charging
The 650 mAh battery lasts one to several days depending on usage. 510 cartridges draw little power, so the battery outlasts dry herb vaporizers by a wide margin.
Charging is via USB-C. Passthrough charging is supported. The battery is built in -- given the long runtime per charge, this is not an issue for most users.
OLED Display and Controls
A small OLED display shows voltage, battery level, and mode. Operation is via a single button: five clicks to toggle power, three for voltage change, hold to fire.
A preheat mode warms the cartridge at low voltage to thin out thick oils, preventing dry hits at the start of a new cart.
Price Comparison and Alternatives
The Uni 3.0 is available across 5 shops and ranks among the most affordable 510 mods. Versus the Uni Pro, it offers a more modern design with similar function.
For even more compact, the Yocan Ziva Pro is slimmer still. The Uni 3.0 wins with its OLED display and adjustable holder.
Preheat and Puff Counter
The Uni 3.0 offers a preheat function: double-click to warm the cartridge for 10 seconds at low voltage. This loosens thick oils for a smoother first draw.
A built-in puff counter tracks your draws -- handy for monitoring consumption and knowing when a cartridge is running low.
510 Thread Adjustability
The Yocan Uni 3.0 stands out among 510 battery mods because of its adjustable width and height mechanism. A sliding plate on top accommodates cartridges from 8mm to 15mm in diameter, while a magnetic ring adapter lets you fine-tune how far the cart sits above the housing. This matters because 510 cartridges vary wildly in size across brands — some are short and stubby, others tall and slim. The Uni 3.0 keeps any of them flush and protected inside the body rather than sticking out the top. Voltage adjusts from 2.0V to 4.0V in 0.1V steps via a dial on the bottom, giving precise control over vapor density and throat hit.
