    Picked one of these up awhile back from the site and it’s still kicking well months later with good usage, great cart vape, don’t think there’s a better one for myself out there yet!

  2. Tricomber (verified owner)

    Picked one of these up during a past accessories sale and glad I did. The unit is built well and works like a charm. These is my first adjustable voltage cart vape and really wished I would have gotten one sooner. The preheat function is also a really nice to have when carts are cold and plugged up.

  3. zenmindstate (verified owner)

    What can I say that hasn’t been already said. Truth is the Yocan Uni Pro has been the best device I’ve used for carts and I’ve tried many similar devices and many box mods too. But I’m terms of consistency/value and convenience this unit has been the best investment I’ve made for using my carts. It also requires very little maintenance and holds a charge well. I only wish the temp/voltage could go down just a little bit but the pre-heat function works well enough for that. Anyways as someone who uses carts daily take it from me I’ve tried many others but this product is the best out there for the price. So happy I bought one! I’m sure you will be too!

  4. bileeckh (verified owner)

    Extremally easy to use out of the box. Mine was almost fully charged. The variable heat setting and auto preheat are both nice.

  5. hbk1908 (verified owner)

    I love this battery so far, in the past I’ve only had the disposable vape carts before, and I always felt like those would get clogged / are very hard to puff on. This device makes the experience of smoking carts way better, i like that you can bring up and down the volts, as well as the preheat function (been using that quite a lot since its getting colder out here)

  6. denis (verified owner)

    Awesome battery so far, love it.

  7. mario (verified owner)

    I already have a similar Yocan, I’m buying another for my friend, it’s really great, especially since you can have 2.0 volts

  8. mzt (verified owner)

    I have used the Uni Pro extensively over the last few years. Overall I have been pretty pleased with a number of the features including the low voltage and preheating options. But over time I am becoming increasingly disappointed with this battery. The big problem I am consistently having is the “no atomizer” malfunction. I have bought four of these so far and each of them has broken down in this way over a relatively short period of time. And yes, I handle the battery gently, clean the parts frequently using isopropyl alcohol and q-tips, reboot the machine, ensure all parts are properly attached etc. But I am just not getting consistent performance and frankly I am starting to get fed up with this battery. Not because it’s not a great design, but because they do not seem well made and break down too easily.

      Hi mzt!

      Thanks for bringing this to our attention! The “No Atomizer” issue comes about from not connecting to the ring inside the vape cartridge. My guess is it’s likely your cartridge connector being too recessed so that it does not connect with your battery correctly. Using one of those tiny screwdriver (for fixing glasses) or paperclip, see if you can pry the metal ring out and try your battery again. Here’s a video to demonstrate how it’s done: https://www.youtube.com/watch?v=MeVzVvDGnOI

      Hope that helps.

    Very killer battery don’t think I will buy another for very long time. Awesome!

  10. louis (verified owner)

    This is amazing !! Pre heat mode with little light inside its super cute loll prevent clogging with pre heat it’s super

  11. Tannis (verified owner)

    This is my favourite battery out there. I love the size and that it holds a charge for days and days. I got brown, and it is beautiful too. I highly suggest this one over the cheaper ones.

  12. purplehaze1117 (verified owner)

    This is the BEST battery on the market!!! I can’t believe the difference!! It’s so good, I’m going to order more for back up. This battery has turned my vaping experience into a new high 😉

  13. losolostsoul (verified owner)

    The yocan uni pro works so well for 510 carts, I urge anyone who uses a standard pen battery to switch to the yocan uni pro! Adjustable voltage so you don’t cook your carts!

  14. hgaallday (verified owner)

    This is the one and only battery you need for carts. Battery is long lasting. Just a great design and a fantastic product highly recommended

  15. Diabo (verified owner)

    My go to battery.

  16. mwgrun (verified owner)

    Easier to order from here then anywhere else. Fast and always giving samples. This YoCan really brought out my Enigma carts

  17. mike (verified owner)

    Highly recommend this battery! Good quality, easy to use and great price!

  18. gsammtl (verified owner)

    Best battery out there …..I recommend it !!!

  19. sl19 (verified owner)

    Best battery on the market. Works great with the enigma cartridges.

  20. smith (verified owner)

    My go to device for carts

  21. Frenchie (verified owner)

    This by far had lasted the longest for me and lasts for more than a week on one charge. Great buy for anyone looking to get a new battery or upgrade from a pen.

  22. taylor (verified owner)

    I never leave the house without this , proper carts work great . Make sure your magnet isn’t to tight no issues 🙂 I love it

  23. Maddy (verified owner)

    One of the best batteries I’ve ever used. Lasts a long time in between charges. Makes every cart taste and feel so good. The price is amazing for this battery and I would recommend this to anyone. very portable, you can take quick hits anywhere on the go. This is my first and favourite battery. Nothing will ever compare to this. I bought it back in May and it still works great.

  24. Direweed (verified owner)

    this thing is amazing, had 2 pens and this one is now my favourite. temp control, fits in pocket, it hides the cart inside the yocan mostly so it won’t get bent. smooth hits

  25. Frenchie (verified owner)

    One of the better vape batteries I’ve owned and the option to fit any sized cartridge is amazing for the price. Easy to use, but mine becomes a little loose on its own (battery says no-atomizer), did that out of the box but still works good.

  26. timothy (verified owner)

    Literally the best vape battery ive ever used, made me frequently use cartridges which i havent ever enjoyed before. This thing plus enigma carts is bomb

  27. vegvinny (verified owner)

    Wanted to try an oil vape so i got this Yocan machine. Fits in the palm of your hand, efficient and quick hits. Love it!

  28. robotstone55 (verified owner)

    I needed a new vape and had taken a chance by purchasing this one. Though the price is steeper (discount code helped a LOT) and the build does not feel metal, BUT still feels solid in the hand. Besides that, the rest of the product is so much better than any vape I’ve had. Temp control from 2.0 is a huge game changer as no pen I’ve used has this, and the amount of thought that went into the vape features such as the cartridge tightening clamp is becoming a better fit to any cart. So far this is a huge success with me I really hope this vape lasts. Scooped up a BC Vape and HVE cart and this thing rips. 9/10

  29. brokengamezone (verified owner)

    Just purchased this battery was very surprised how well this works compared to the other batteries I’ve tried. With this battery I’m not getting the scratchy burnt throat feeling which allows me to smoke even more I’ve never gotten so high from vapes before got so high that it felt as if i were smoking actual bud started falling asleep in my computer chair I smoke 3.3v – 3.8v no burnt coils nothing! smoke is smooth and good tasting will never switch back to those cheap pens. If your a cartridge smoker don’t think twice just buy this instead of any others.

  30. jroca87 (verified owner)

    Don’t bother spending your money on any other battery if your into cartridges! I was using one that only went as low as 3.3, got the uni pro and now I’m not tasting burnt coils, and it just feels so much better in the hand.

    Buy this!

  31. MC1976 (verified owner)

    Ok, this thing is fking AWESOME!! Its just so easy to use out of the box and incredibly effective in produces vapor quickly with that preheat function. Ive been waiting to get one of these for a while as Ive been following the progression of what’s going into carts these days and I gotta say, with a full spectrum cart you really cant go wrong. Ultra discreet (you could use this virtually anywhere, anytime) super strong now with the new carts around, and cool af. I absolutely LOVE my new toy. I got a couple HVE carts and a BC vapes honey oil if you want to check those for further review. Cheers guys!

  32. G W (verified owner)

    Yocan has the best devices!! I have tried multiple 550 thread vapes and this one is truly the bomb! Last for 4 days moderate use. Awesome device!! Scoop er up, will not be disappointed

  33. marmencollins (verified owner)

    You well not be disappointed. Great quality battery lasts forever. highly recommended. Cheers…

  34. finallytall (verified owner)

    This is a powerful little guy and worth the $.
    There are so many options with this one and being able to get such a specific temperature is a game changer for sure .

    If you’re on the fence – go for it , you won’t be disappointed.
