HexOhm V3.0 Review:

An American made, limited edition, and powerful box mod is going to rock the vaping world with its simple and screenless design. So without further ado, we will take a closer look at the HexOhm V3.0 by Craving Vapor ($199.99 from VaporDNA).

HexOhm V3.0 Design and Interface

The HexOhm V3.0 is a well-built, simple, fantastic looking box mod that is powered by two 18650 batteries. It’s a big improvement from its predecessor the HexOhm V2 with its maximum output of 180W, a master on and off switch for safety and improved battery bay with a strong magnetized door. The body is made from high-quality aluminum painted in powder coated finish. It has a dimension of 103mm by 51mm by 27mm and weighs around 225g, this device is quite heavy yet robust. It has a big HexOhm logo on the front side, the battery cover has a limited edition anarchist logo on it, and a big solid firing button on the front, which is very responsive and comfortable. Below its firing button, there’s a small potentiometer that lets you adjust the output power from 0 to 100W by 10 increments. There is also a unique serial number on each HexOhm V3.0 for warranty purposes in case you encounter any problem with your device. Keep in mind that this device comes with lifetime warranty, so this should come in handy in case of any flaws.


The 510 connection in this device comes with a spring loaded center pin which is compatible with any tanks we used, from 22mm to 25mm sub-ohm tanks, all are perfectly flush onto the device; no issue at all. Having to look at the mod, the battery bay is molded from ULTEM with spring loaded brass contact which can withstand higher temperature making it durable and safer to use. Its battery cover has a very strong and tighter grip making it rattle free and spill proof from your e-Juice. Another astonishing feature about the HexOhm V3.0 is its master switch that lets you turn on and off the firing button which is perfect for traveling or tossing it in your pocket without any worry of accidental firing.

HexOhm V3.0 Performance and Vapor Quality

Keep in mind that this is a mechanical mod  – recommended for medium to advanced vapers only. You need to know the ohms and amps of your atomizer first before using this device because this might stress or wear out the proprietary chipset. Although this mod comes with reverse battery protection that will protect the chip, it is something you really need to take seriously or else it will be a big trouble. The proprietary chipset has a 30Amp max output and can be vape as low as 0.1 ohms at 45W or less, which is more than enough for most users.

Another fact about the HexOhm V3.0 is that there is no screen display to check the voltage or wattage, so you have to check it by taste using the potentiometer that can be gradually adjust using your fingernails or screwdriver. It’s fairly simple and straight forward, but at the same time, you don’t know what you are vaping at.

When it comes to overall performance, the HexOhm V3.0 really stands out above the rest. Vapor production is awesome and the battery life is great. Although, we have some issues when trying to open the battery cover, because of its powerful magnets. The performance and the size of the mod are remarkably impressive.

      I’m a user living in S.Korea. I got one of these from a Korean supplier, and just so you know, I’m pretty sure the product supplied here is the same one sold in US. RDTA, RDA, RTA are all usable, no question asked. Only one thing to remember, ALWAYS know what you vape out from ; what ohms are you using. I’m sure you’ll be satisfied as I did. Hope you get your hands on these. Good Vapes 🙂

    I was a little surprised to see this at the top of the list… I’ve been vaping for almost 7 years and I’ll admit that I’m a bit prejudiced against mechanical mods. I’m sure they are great if you’re an OCD electrical engineer, for the rest of us they seem like a disaster waiting to happen. I could understand if these were priced at $10, but I fail to see how a $200 price tag is justified. Just from reading this review, I’m not sure why this would cost 4x as much as a Wismec RX200. Can someone clue me in to why I’d want this over one of the others?

      hey MAX the only reason mods like these carry this price tag is because they have a lifetime warranty. i could break enough parts in a lifetime for sure and it would be more than 200 bucks…

    Bit unfair to state that all you’re paying for is a warranty. What you’re really paying for is quality engineering specific to the US. This hasn’t been designed there, farmed out to some sweat shop in China then had some YouTubers name slapped on it.

    If anything, the warranty is them saying ‘hey, we’re so confident in this products quality and durability that we’re willing to give away a life time guarantee!’

    How the heck is 45w at 0.1ohms enough for most users? You would barely get any vapor at all at that wattage with such low build.

    I think you are wrong, its able to fire much higher than 45w at 0.1ohm
