The Yocan UNI Pro, also known as the Wulf UNI Pro, is an upgrade to the original UNI Since its predecessor was quite popular, Yocan decided to go above and beyond to design the UNI Pro with new, much-needed features to enhance its appearance, functionality, and performance of the device.

The biggest upgrade on the Uni Pro is that it comes with adjustable voltage. It also has more features like 10-second preheating and 15-second shut-off. What’s more, the device has an upgraded design including a new OLED screen, up/down buttons for controlling the settings, and an e-juice window. Just like its predecessor, this device It is safe to say that the Yocan UNI Pro is a worthy successor to the original UNI. 


The Yocan UNI Pro looks strikingly different from its predecessor. The device has the same C-frame, but it is smaller, and the edges are sharper. The device looks sleek and modern. The dimensions of the UNI Pro are 75.5mm by 36.5mm by 25.7mm. It has a rubberized finish which is nice in the hand.

There is an OLED screen on the side of the device. Above the OLED is the firing button, and below it are the up/down buttons as well as the USB charging port. The one thing that makes this device stand out is that it can fit cartridges of varying sizes because you can adjust the height and width of the cartridge compartment. Ingenious, right?

On the back of the Yocan Uni Pro, you will find a wheel that controls the width of the atomizer compartment, and there’s also a switch that controls the height. You can fit any cartridge with a diameter of around 7mm to 14mm in this mod. There’s also a window on the back of the device where you can see the oil or e-juice level of your cartridge.

The UNI Pro is compatible with 510 cartridges. The device comes with a magnetic adapter that you need to fit onto the end of your cartridge and then slide it into the cartridge compartment on the mod.

Battery Capacity

The Yocan UNI Pro has a 650mAh battery, which is not bad for such a portable device. It comes with a micro USB cable for charging it. Unfortunately, the device doesn’t support pass-through so you can’t vape while it is charging.


The performance of the Yocan Uni Pro is worthy of applause. All you need to do is press the firing button five times quickly to turn it on/off. When the device is on, it will automatically detect the resistance of the coil in your cartridge and display it on the screen.
