SMOK H-Priv Review

SMOK H-Priv Intro

SMOK has come a long way since the fiasco of fake temperature control on the SMOK XPRO M80 Plus a year ago. Smok’s temperature control chips are now up to speed with other manufacturers in their price niche (Joyetech, Sigelei, etc.), and their mods continue to improve in design and innovation. The H-Priv 220W TC is their most powerful box mod to date, and arguably their most interesting.

Notable Remarks


The SMOK H-Priv 220W TC box mod is currently available either as a Mod Kit (containing only the box mod) or a Full Kit (bundled with a SMOK TFV4 Micro Sub-Ohm Tank). Online prices for the two kits are typically in the range of $45–55 for just the mod, and $60–75 for the bundled Full Kit with the TFV4 Micro Tank.

Design of the H-Priv

SMOK H-Priv Screen

The first thing that leaps out to the eye about the H-Priv box mod is the aesthetic of the case design. While slightly smaller than some of its dual-18650 powered counterparts, the zinc alloy rectangular case (available in silver, white, or black) has nicely rounded edges and a striking color contrast. Rather than a typical firing button, the H-Priv uses what SMOK call a plastic “red triangle design” firing bar that runs almost the length of the mod. The addition of a pull-out battery cover at the bottom made of the same red plastic gives the mod the look of a piece of industrial art rather than a typical box mod. Not everyone may like that, but I find the appearance stunning. I liked the side-firing rounded plate of the iStick 120W TC, and I approve equally of the “red triangle” firing bar. No one will ever have to fumble for a small firing button on this mod. For a rectangular design, the H-Priv feels very good in the hand.

In addition, the display screen and up/down adjustment buttons are located on the mod’s top plate between the 510 connector on one end and the red firing bar that runs down the other side. Relatively few mods are designed with a top-mounted display, and especially not one of such generous size as the H-Priv. Beyond that, the H-Priv offers menu options for changing how long the screen is illuminated before shutting off (to save battery power) and for lowering the contrast of the OLED screen for a stealthier vape experience. Screen brightness is adequate for indoor vaping, but in bright sunlight? Probably not.

SMOK H-Priv Front

The location of the OLED display on top seems iffy to me. Will it short from leaking tanks or RDAs? I don’t know, but I’d think it possible. Also, the tank I used for testing (a Council of Vapor RST) happened to align when screwed on so that one of the air intake slots was directly next to the screen. The small release of vapor from the air intake slot was enough to fog up the screen, and I found it a little aggravating to have wipe the screen with my thumb fairly often. The display screen itself is fine, although I wished it were brighter. Numeral size of the power in wattage mode or the temperature in TC mode is large and easy to read. Even the smaller numbers — for resistance, puff count, voltage, and intensity of ramp-up — are large enough that even my old eyes could read them without difficulty.

Functions, Interface and Performance


Temp Control works with all the usual suspects: Nickel, Titanium, and Stainless Steel wire, in either single or dual coil builds, and TCR values for each wire type are user-adjustable. Both Wattage and Temp modes offer different “outputs” — Max, Min, Hard, Norm, and Soft.

In addition to Wattage Mode and Temp Mode, the H-Priv also offers “Power Mode.” The chip will remember 16 different power settings (M1 through M16). I can see how this might be useful for someone who changes tanks and builds often, but it seems almost OCD geeky to me. How does one remember 16 different settings? I still haven’t figured out how to set any power other than M1, but that’s OK, since I tend to use the mod in Wattage Mode.

Perhaps I will warm over time to the slide-off battery cover, but so far I’m not a fan. The red plastic cover fits into slots on both sides of the bottom plate, and while taking it off is easy enough, putting it back in place after swapping out the batteries requires fairly precise alignment and the application of considerable pressure, which I found slightly annoying.

SMOK H-Priv Side

Also, the H-Priv has a noticeable firing delay. SMOK’s engineers may have their reasons for that, but I guarantee that vapers won’t like putting up with a firing delay.

I don’t have electrical testing equipment. For all the power graphs, I’d refer readers to Phil Busardo or Daniel from DJLsb on YouTube. I don’t know if the H-Priv can actually crank out 220 watts, nor do I care. I judge performance of a new box mod in the old-fashioned way, by comparing how it feels to other mods I own, using the same tanks. That’s hardly scientific, of course, but close enough for horseshoes. Performance of the H-Priv passed my comparison test with flying colors, but keep in mind that I never asked it for more than 70 watts.


  • Innovative Design
  • Striking Aesthetic
  • “Red Triangle” firing plate
  • Good performance
  • Modest price for so many features


  • Top-mounted display seems vulnerable and fogs up
  • Menu navigation is non-intuitive and causes errors
  • Sliding battery cover didn’t thrill me
  • Noticeable firing delay


SMOK may not challenge Evolv or Yihi for high-end chip complexity, but the H-Priv 220W TC box mod is crammed with features and options, and at a moderate price point. Performance in either Wattage or TC mode is what we’ve come to expect these days, which is to say, good. The menu navigation and firing delay are both frustrating and make me wonder what SMOK was thinking to release a mod with those flaws.

I’ll give the H-Priv Mod a passing grade and a recommendation, but with reservations.

Maybe I’m just stupid but how do you turn it off?


is this regulated on unregulated ??


I love the H-Priv 220w. I have a velocity RDA and with the right build this is a cloud chucking machine. 22guage Kanthal A1. Around .25ohm. I now have a mech mod and it blows this (on cloud proportion) out of the water. I have had no problems with the H-Priv. I love it.


I find that taking off and replacing the battery cover on the H Priv is very easy once you figure out the right way to do it.


a couple of question for people who have used it the Smok HPRIV for more than a month:
1- how is the mod ? heating issue ? does the firing button get stuck ??
2- how is the tank in the kit ? does it leak ? good flavor ?
will be nice to know , before i buy it 🙂


1# i brought mine this year oct 9, the atomizer leaked onced,probably bad gasket,
i been using the x cube for 8 weeks, i still have it and it works better

2# i sent the tank with atomizer because it was stuck and since i twist it too much, someone become lose or broken inside, im no expert in fixing tanks so i sent my tank to epuffstore in ca, they refused and sent back to me, soo in less than 1 month, i lost money because they wouldn’t refund me, it is worthless, i contacted Smok, they said “use rubber gloves and screw it”, and if i did that, the whole tank and atomizer would broke.

3#i use a hexagonal tool and open the tank, to my surprise, it is stuck in the

3# epuffstore sent back my h priv because they can’t fix

4# Smok, can you fix this problem? i should receive medal of honor for opening this


here is the comment that would’ve broken my tank smh,,!!!!! Smok, your products are awesome but sometimes you need someone who can really help,if this was ur products, you wouldn’t be pleased. thank you for listening. Deweyy


Ive had the mod for a few months now and the mod never gets more than slightly warm and I vape around 100 watts regularly. The trigger never sticks and the mod never misfires. I dont have the tank so I cannot comment on it.


1 – the mod is great. No problems with it. The tank can get very hot, but not like it can burn your skin. The firing button hasn’t got stuck once, so no problems with that either.
2 – the tank has leaked a couple of times unfortunatly. The flavor could be better.

Overall, I’m very happy with it. Only the tank I got with it is really small, but then again you can just buy a bigger one and replace it.


What do you guys like now for smaller box mods in the 100w and over range? Not DNA due to cost. Looks like they all have their issues, from seeing the reviews. Something nice to handle, not as wide as my IPV 3 Li. Also, TC performance is not important…. I rarely use it.



I just bought the smok Hpriv and its very good.
However i have the uwell crown with 0.5 ohm coil running in VW mode and i noticed that the resistance is climbing up to 0.6 as i vape.
I know this happens in TC mode but is it normal for resistance to climb in watt mode?



am not a super expert, however my friend 213 does the same thing, i guess it varies when the coil heats


Finally mi H-PRIV came. It’s beautiful and a bit heavy. The trigger is not so clicky and I don’t mind the delay. What bothers me is the menu system and long press fire button to confirm action. And the door. The gold plated contacts are nasty and you have to watchout they scratch easily batteries (stronger pressure needed to close). Maybe they could be more flat. TC works fine I used 316L no problemo, no cotton burn. Only issue I had was with genitank. If fully screwed it couldn’t recognize tank and asked “new tank” several times. Crius sat down good didn’t cover my display and no issues. Guess genitank has cheap 510 I don’t know.

How tf do i get the thing out of stealth mode?!?


Have to lock it 5 clicks wit fire bare than hold fire bare and ur + button


I got an email this morning informing me about SMOK offering an firmware update to remove the firing delay on the H-Priv. SMOK defends their reasons for programming the brief delay as a way for the mod to distinguish between a single press to fire and three presses to unlock, but they’ve responded to the requests of some customers to make the H-Priv fire instantly.

Vaping360 was told by a SMOK representative that the upgrade and instruction guide would be available on the SMOK site as of today (Monday, May 31st), but that’s been delayed. At least we know it’s in the works, though.


Have you tried the update? How is it? I planing to buy one~


Yeah.. firmware update is work for firing delay.. its great..


I bought one today and did the upgrade as soon as I set it up at home. I can say it fires instantly without any delay. I have numerous mods, regulated and unregulated and I can for sure say I love this mod and the whole setup. I got the kit wit the micro tfv4 tank

Great review Bill.. I have the X cube II 160w and it seems like they are very similar in the menu don’t know if the same chip just in 220w version, I really like my Xcube and I think this one is a great mod also, the design is a win and I think I would like this mod as I like the other one. It’s not a con to me with the screen on top actually I think it’s great, I had one tank leak on the mod and it went over the screen but it keept tight and no juice went indside not even where the buttoms is, I’m of cause talking about my Xcupe II don’t have the H-priv
