Yocan Uni 3.0 vs Vane 2: Big Magnetic Cart Chamber
A reviewer who put the Yocan Uni 3.0 through a couple days of lunch-break rips calls it one of the most versatile 510 box mods on the market, thanks to a magnetic drop-in adapter and a big shutter-style chamber that fits carts up to 42 mm tall and 16 mm wide.
What's in the box
Uni 3.0 battery, USB-C charger, magnetic 510 adapter, a small silicone cart sleeve, and the user manual. The adapter screws onto the bottom of your cart and then just drops magnetically into the chamber.
Controls and voltage
Five clicks to power on, three clicks to pull up the on-screen menu. Voltage runs from 1.8 V to 4.2 V in 0.1 V steps. There's a preheat function and a session timer he leaves set to about 15 seconds.
The on-screen UI cycles through a few display themes including a planet and a cat animation.
Chamber and magnetic adapter
This is the part he keeps coming back to. The chamber has a shutter-style ring that tightens around the cart, so skinny 1 g carts don't rattle around and thick carts still drop in clean. He says it'll take any cart up to 42 mm tall and 16 mm wide
— bigger than most box mods in this price range. The magnetic adapter means no screwing and unscrewing every time you swap carts.
Battery and charging
He was hitting it 10-15 times a day across two days and it was still sitting at 50%. USB-C charging pulls it from ~30% to 100% in about 30 minutes.
Concealment sleeve
One feature he liked: a three-position silicone sleeve that slides over the cart window. Fully closed it looks like a standard nicotine vape cart; half open and fully open settings show different amounts of the cart through the window.
Size and feel
He notes it's noticeably thicker than the Yocan Vane 2 — roughly 25% chunkier — so tight pants pockets will feel it. It has a small loop on the side if you want to run a lanyard through it.
Verdict
He calls it one of the most versatile 510 box mods out there for cart compatibility, with quick USB-C charging, adjustable voltage, and the magnetic drop-in making cart swaps fast.
