510 Thread: Universal for All Cartridges
The Uni Pro uses the 510 thread -- the most widespread standard for vape cartridges. It fits virtually every prefilled oil and concentrate cartridge on the market.
The adjustable adapter accepts cartridges of different diameters. A magnetic ring at the cartridge base provides secure hold. The housing partially conceals the cartridge, making the setup more compact and discreet.
For users who want to try different cartridges, this universality is a major plus.
OLED Display and Stepless Voltage Control
The Uni Pro features an OLED display showing the set voltage, battery level, and puff counter. Voltage adjusts steplessly from 2.0 to 4.2 volts in 0.1 V increments.
Low voltage (2.0-2.5 V) delivers mild, flavor-rich vapor. High voltage (3.5-4.2 V) produces denser clouds. The optimal setting depends on the specific cartridge.
A built-in puff counter shows how many draws have been taken. That helps with dosing.
650 mAh Battery and Preheat Function
The 650 mAh battery is adequate for a 510 mod -- cartridges consume much less power than wax coils. Depending on voltage and draw length, one charge lasts many hours.
The preheat function briefly warms the cartridge at low power. Useful for thick oils that become viscous in cold temperatures. Activated by double-pressing the fire button.
Passthrough charging allows use during charging. Heat-up time: just 2 seconds.
Compact Design and Discretion
The Uni Pro is small and inconspicuous. The housing partially encloses the cartridge so it is barely visible from outside. That makes it significantly more discreet than pens where the cartridge sits exposed on top.
The magnetic adapter holds the cartridge securely yet allows quick swaps. The height adjustment accommodates different cartridge lengths.
For everyday use -- pocket, car, or desk -- the Uni Pro is one of the most practical 510 mods.
Price Comparison: 6 Shops from 16 Euros
From around 16 euros across 6 shops, the Uni Pro is one of the cheapest yet most feature-rich 510 mods available.
Compared to the Yocan Ziva Pro (from 11 euros), the Uni Pro offers the OLED display, stepless voltage, and puff counter. The Ziva Pro is even more compact but has fewer settings.
For users wanting full control over their cartridges, the Uni Pro is the better choice. Those who just want to plug in a cartridge and vape can save with the Ziva Pro.
Voltage Adjustment
The Uni Pro gives you voltage control in 0.1V steps from 2.0V up to 4.2V. Lower voltages (2.0–2.5V) preserve terpene flavor and produce thin, smooth vapor. Mid-range settings (2.6–3.2V) balance flavor and cloud size. Higher voltages push bigger clouds but can burn through oil cartridges faster.
The adjustable 510 adapter holds cartridges from 8mm to 15mm in diameter, so almost every standard oil cartridge on the market fits without wobbling.
