Technical Specifications

Why Choose the Yocan UNI Pro?

Different cartridges perform best at different outputs, and a battery with only three or four presets means settling for whichever is closest. The UNI Pro removes that compromise, which matters most if you use more than one type of cartridge or are still working out what suits you. Its adjustable frame also means you're not tied to one cartridge size or shape. If you don't need the adjustable frame and would prefer something much smaller, the Yocan Kodo Pro offers the same fine voltage control in a pocket-sized body.

This device is sold strictly for use with prescribed medication only.

Caring for Your 510 Battery

These are general, basic care tips suitable for most 510 batteries. Your device manufacturer's own care instructions may differ, always refer to the instructions supplied with your device where the two don't match.

• Periodically unscrew the cartridge, even if you're not swapping it, cartridges can occasionally seize in the thread over time if left in place for long periods.
• Wipe the connection threads and centre pin with an IPA wipe every so often, oil residue and dust here can cause weak vapour production or a battery that won't fire properly.
• If your device has a preheat function, use it before each session, this helps the oil flow more smoothly and reduces strain on the battery and connection.
• Storing the device upright where possible helps prevent oil pooling into the mouthpiece, though there's no need to worry if this isn't always practical.
• Avoid extreme temperature and pressure changes (for example, a hot car or a flight), these can affect oil viscosity and lead to leaks.
• Don't overtighten the cartridge when attaching it, this can damage the seal and make it harder to remove later.
• Handle with care, avoid dropping or excessive shaking, which can disrupt internal seals.
