Hamilton Devices is proud to present the Shiv – our first-ever variable voltage battery. With a mechanism that allows users to adjust the battery voltage, it’s designed to offer vapers not only the ultimate hits but also the ultimate control over their vaping.

The Shiv is equipped with a deploy and retract technology with which you can adjust the voltage to a tenth of a volt or as per your requirements for a more precise heat control. How does it work? It’s quite simple really: On each click of the ‘plus’ (or ‘minus’) adjust button, the voltage increases (or decreases) by 0.1 volt.

Besides variable voltage adjustment control, the Shiv also offers discretion. As you push the thumb slide up, the cartridge is instantly deployed, ready for use and as you move it downward, it is immediately retracted back to its concealed position. Its stealth use makes it an instant hit with all types of crowds as does its aesthetic appeal! Its sleek build lends it a contemporary look. Besides, its design makes it hard for onlookers to guess what it’s really used for, unless you tell them! What’s more is that you can even have the color and branding customized to fit your unique needs.

The Shiv’s small size makes it easily portable so you can carry it with ease wherever you go. Simply slide it into your trouser packet or carry it in your purse so you’re not deprived of your next puff, even on the go. But don’t be fooled by the battery’s tiny dimensions – it works with both 0.5 ml and 1.0 ml cartridges. Are you ready for a vaping experience that you can control? Order the Shiv today!

MAINTENANCE TIPS: Any device dealing with oils has the potential to leak and general cleaning maintenance will keep the device at its optimal performance.
RECOMMENDED CLEANING: 1-2x per battery charge or depending on usage with a Q-Tip and rubbing alcohol.

    I really love the battery as i am low on money and normal pens only go down to 3.2 volts and carts are meant to operate between 2 and 3 volts. I started saving sm money and if I gave people hits i would know that i’m chillin so when they blinker it it doesn’t kill my cart. P.S. If you are going to get this be careful to not strip the threads and if u care about the screen staying perfect while being active get a small fabric cover that size for it.

    Finally! A well built type C charging vaporizer that packs a punch and fits in your pocket. Thank you so much for creating such a strong, cool, safe and smooth product!

  5. Cody (verified owner)

    Absolutely amazing device best quality and super fun to play with

    This is one of my favorite units. Not always ideal for travel as it doesn’t like getting dropped in water OR dropped on hard surfaces, this is your home vaping unit. This is the stylish robust vaping mod you use while chilling around the house. Maybe it will be OK for you if you are hiking but I generally leave this one home on Kayaking trips! MY ONLY COMPLAINT is lack of color options. You guy could sell tons more of these offering some cool colors such as flat dark earch, forest green, pink, purple, orange, teal etc. Look at all the colors Yocan has for their stuff, come on people, its finish finish paint, offer us more options, I’ll buy multiple colors!

    Just love this little device.

  11. Geoff (verified owner)

    One of the best 510 thread batteries I’ve used in awhile. Has great air flow, strong battery, usb-c, and the switchblade mechanism never gets dull. It’s got great weight to it, and thanks to that strong 900mah battery I’ve gone through almost 3 1gram carts @2.6v’ss on one single charge.

  12. Alissia Triminio (verified owner)

    The thumb slide “button” was off when it arrived . Spot of super glue fixed it. Would get a 5 if not for this. Love it.

  13. Keith Bachmann (verified owner)

    Great but I’m having a issue w the device

  14. Salvador L. (verified owner)

    Best battery I’ve owned. Exactly what I needed.

  15. Kenshiro (verified owner)

    As advertised, neat little battery.

  16. Rowan (verified owner)

    Hits like a dream. The cart doesn’t like to lock into place all of the time but I just have to push it down farther when the slides down and that fixes it. Worth every penny.

  17. Geno (verified owner)

    Super cool!!!

  18. Matt (verified owner)

    Love this thing sooo much! Just like an OTF knife like an ultratech.

  19. Steven Wise (verified owner)

    I’ve had my Shiv for about a month now, got it as part of that $35 dollars Year Years sale, and WISH I had gotten two!

    I only have one real complaint, that is the lack of colors. I’ve actually seen the inside of one of these and the zinc chassis and the otter slip over cover as just sprayed with a rubberized coating… So, um, why not offer different colors?!!! Such a simple thing sot do, just paint those two parts. I don’t even care if the side button remains black. I’m actually going to order a second one, strip is down and have a Cerakoted hot pink for my girlfriend. She didnt want one due to lack of colors, she got the new pink Yocan Unimod Pro, but I talked her into one of these if I Cerakote it! Also this needs a couple more features. Multilple puff counters for poeple who swap carts would be HUGE! Like a P1, P2, P3 or PC1, PC2 etc. You select the one you need before firing and the counts so on the one selected. I normally smoke on 2 or 3 different carts as a time through out the week.

  20. Keith (verified owner)

    The quality is there

  21. Dakota W. (verified owner)

    It’s a solid device but mine won’t lock the cartridge into place unless I pull up on it to lock it into place. Other than that it’s a really good device.

  22. Andre Peck (verified owner)

    I love the design love how long it lasts with the battery life how many cartridges you can use before you charge it and makes th cart hit 10x better

  23. Anonymous (verified owner)

    Love it. Wish it were a little less expensive.

  24. Robert (verified owner)

    Works great!

  25. Vernon Brechin (verified owner)

    Excellent product

    Love it so far, zero complaints, it makes my cart draw like a pencil

  28. Elizabeth Mason (verified owner)

    Very nice but it burned one of my carts I think I just had it set too high.

  29. Garrett (verified owner)

    I was using a yocan uni pro before this unit and loved it. The shiv has a bigger battery, is made from higher quality materials and just looks better. The cart rapidly retracts and pops all the way up just like a switchblade. The only thing the uni pro has that this doesn’t is multiple height settings for the cart and a preheat function. If you catch this on sale it’s a steal, but not a bad value even at full price

  30. Robert (verified owner)

    The SHIV is awesome it hits so good you can adjust the temperature at a low temp so the hits are so flavorful and you can adjust it to a such a high temp to get a great big hit and The battery life is awesome you don’t have to keep recharging it Great product I would recommend this to all my friends

  31. Patrick D. (verified owner)

    Fantastic piece of equipment, however only at the 50% rebate y’all did for New Year’s weekend. Full price FAIL.

  32. Kevin H. (verified owner)

    Battery works great so far.

  33. Anonymous (verified owner)

    It’s is amazing

  34. atwhite1512 (verified owner)

    Compact, but feels great in hand! The “shiv” feature is a cool trick to use around others. Awesome! 😀

  35. Isaac (verified owner)

    Battery draws and hits smoothly on all temps. It is my new daily battery.

  36. Matthew Durney (verified owner)

    Hello fellow 420 smokers I have 6-7 different types of vap batteries that all fall short of the Shit! I mean the Shive is a top quality oil vaporizer that really has stepped up the oil vap game for sure.. I love the adjustable heat you really can dial in the perfect temperature for a perfect tasting huge vap clouds from this bad boy..Looking forwards to the next versions of the Shive…..

  37. David (verified owner)

    This thing is slick, solid and well built, and hits like Mike Tyson. I took a chance ordering this device knowing very little about it and I am not disappointed. Well done.

  38. Asher Thurer (verified owner)

    Fantastic battery, easily became my everyday carry. It’s got a very nice heft to it, a solid metal build that makes it feel like you could chuck it against a wall and you’d just pick it up and dust it off to keep using it no prob. Variable temp is a must and works great with this guy, letting you really dial in your preferences. Oh, and it charges with USB-C which is pretty sweet too.

  39. A F. (verified owner)

    Hands down the best 510 battery I’ve used. And I’ve used quite a few in the past 10 years. Worth the price if you are a regular 510 user.

  40. Steve (verified owner)

    Top shelf battery. I love the weight of it. Great feature being able to tune in your voltage to taste.

  41. Danny Perez (verified owner)

    Love this battery. It has a bigger battery size than most 900 maH. I love adjustable voltage and the “shiv” mechanism. Has a great weight to it without being huge. Glad I got it over the yocan uni pro.

  42. Jamesjuno (verified owner)

    The best 510 battery I’ve used so far. I only had this a short while but so far every cart I try works perfectly.

  43. Rob (verified owner)

    Have not used it, yet, but cannot wait to do so.

  44. Ryan Russell (verified owner)

    I really enjoy the battery life of this thing. The spring is pretty cool, although I did freak out when it got off its slide. Flipping it over and locking the cart in place fixed it. Occasionally is still gets off track from time to time, but its a great product.

  45. Harry (verified owner)

    Best cart battery PERIOD ! 🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥👌🙏
