Yocan UNI 3.0 Review: Is It Worth The Hype?

I’ve been loyal to my Yocan UNI Pro Plus for years. It’s survived drops on pavement, a little water damage, and the inevitable disappearance into my car’s black hole of a center console—yet somehow, it still fires up like a champ.

But after years of using the same vape battery, I started wondering… at what point do I consider an upgrade?

With new vape batteries and flashy gadgets constantly hitting the market, it’s easy to get caught up in the hype. If I upgraded every time a new version dropped, my wallet would’ve tapped out long ago. But after years of loyalty to the same setup, I figured I’d earned my badge in vape sustainability.

Yocan recently launched the newest addition to their family of UNI vaporizers: the Yocan UNI 3.0. It’s been a while since they released a new version, so as a longtime vaper (and previous Yocan vape battery buyer), I had to see if this one was actually worth the switch.

Here’s my honest take. 

Ripping open the box, my first thought was: Damn, this thing is slick.

Taking the Yocan UNI 3.0 out of its box reminded me of unboxing a Blackberry back in its heyday. Everything from the big screen to its ergonomic palm size gave me some serious nostalgia, but unlike my old BlackBerry, this vape won’t require a thousand battery pulls to stay alive.

This is one of the first handheld cartridge batteries and the wide 1.93-inch HD animated screen was a huge flex. Most cartridge batteries are pretty basic—slap a button on there, maybe toss in an LED light, and call it a day. But this thing looks like it could run diagnostics on a spaceship. 

Yocan UNI 3.0: Visuals

While the screen displays the basics—like real-time updates on battery life, voltage, and puff count—it also features three UI modes to choose from, depending on how much personality you want your vape to have:

• Classic Mode – Straight to the point. Voltage, battery life, puff count. 
• Planet Mode – A sleek, futuristic aesthetic with some extra motion.
• Shiny Cat Mode – A floating space cat appears every time you take a hit. No explanation, no real reason, just vibes. 

I seriously love Shiny Cat Mode. Because why shouldn’t I be greeted by a spaced-out kitty every time I go for a rip? Also available in colors black, white, light blue, rosy, green, rose gold, or violet—I snagged rose gold for an elevated look.

Visually, the Yocan UNI 3.0 is a step up from the usual vape batteries out there. But the real test? Seeing if it actually hits as good as it looks.

I’m extremely picky. I only use live resin cartridges, never distillate—because if I wanted flavorless vapor, I’d hit a USB drive.

So when testing a new vape battery, my standards are high. I need something that won’t burn my oil, has variable voltage settings, and actually lasts longer than a night out.

To put the Yocan UNI 3.0 through its paces, I grabbed my favorite Neon Sunshine cartridge and got to work.

Like other Yocan UNI vaporizers, this vape can hold various cart sizes. The Diameter Adjustment Dial accommodates anything from 11mm to 16mm—which, let’s be real, is huge. I’ve personally never seen a 16mm cart in the wild, but if you have ’em, the UNI 3.0 can take ’em.

It also has an adjustable height switch on the back, meaning you can line up your cartridge just right so there aren’t any awkward gaps or janky fits. Once everything was screwed in place, it was time to power her up.

Turning on the Yocan UNI 3.0 is easy. Just whisper in her ear. In all seriousness—click the main button five times to activate the device. It uses a powerful 650mAh battery and fast USB-C charging along with a 1.8V 10-sec preheat function. This is a big plus for me because I refuse to keep track of micro-USB cords like it’s 2015.

I’ve never been a fan of preheating cartridges unless they’re cold or clogged because I swear it eats a little extra concentrate. But, for the sake of the full experience, I gave it a shot.

Like many of their other devices, the Yocan UNI 3.0 ranges in voltage from 1.8-4.2V. I’ve always been happy at 2.8V for maximum flavor and clouds without hunching over in a coughing fit (unless that’s your vibe).

For the sake of testing, I cranked it up to 3.5V. This gave me way bigger clouds and a stronger hit, but I could definitely feel the heat creeping in. It’s solid if you like stronger hits, but for me, 2.8V to 3.2V was the sweet spot.

If you like the feeling of your soul leaving your body while exhaling a massive cloud, then the 4.2V setting is for you. My cart could handle it, but I wouldn’t recommend this voltage unless you really want to rip through your oil fast.

Another feature I appreciated? The 15-second cut-off. I’ve lost more oil than I’d like to admit to accidental button presses, and this stops that from happening. No more discovering a half-empty cart because my vape decided to auto-sesh in my pocket.

Damn, did the UNI 3.0 deliver. Smooth, flavorful draws (shoutout to live resin) with respectable clouds, even at those lower voltages. The real win was how well it preserved the terps. Some cheap pen batteries absolutely mute flavor into oblivion, but this one kept my live resin cart tasting exactly how it should.

This is a big one for me, especially since live resin cartridges can get gunky over time. The 1.8V 10-second preheat function actually works, but without that annoying burnt oil taste some preheat settings leave behind.

I let a half-used cart sit for a couple of days (which usually means a clogged airway), and the preheat melted through it smoothly. It didn’t completely clear a really clogged cart on the first try, but a second cycle did the trick. Definitely a plus for cold weather vapers or anyone who has carts that clog easily.

The Yocan Uni 3.0 is a solid vape. It’s not some gimmicky vape that looks cool but flops in performance—this thing actually delivers. The adjustable cartridge fit, customizable voltage, and UI modes make it one of the better cartridge batteries I’ve used.

If you don’t care about fancy screens or adjustable settings, you might not need all the extra features in this vape. But if you want full control over your hits, a battery that doesn’t feel flimsy, and a little personality (shoutout to Shiny Cat Mode), it’s worth the upgrade.
