A clever redesign from SMOK’s R&D team has produced another eye-catching, hot performing advanced device that has clearly been built to last, and to impress.

Its striking features are reminiscent of its predecessor the X Cube ll but with that added touch of class, and improved performance.
Their new H-PRIV power range starts at 6watts and boasts a maximum output of 220W.

Firing in Wattage mode down to 0.1Ω and up to 3.0Ω whilst in Temperature mode from 0.6Ω up to 3.0Ω with a temperature range set between 200°F and 600°F (100°C-315°C) the H-PRIV should be able to satisfy the demands of most of today’s hardcore vapers.

SMOK’s engineers have also been able to reduce the overall size and weight compared with the X Cube ll. So, not only is it a more appealing design but more compact and lightweight too.

So, let’s see what’s in the kit and take a view on its full functionality and overall performance.

The H-PRIV Kit has been sent directly to me for review from SMOK TECH for this review.


The device arrived in a shrink-wrapped box that includes a picture of H-PRIV Kit on the front side of the outer sleeve with the SMOK logo situated above. Below the caption “Creativity Is Beyond Imagination” and underneath the picture the product name H-PRIV Kit.

On the right-hand side of the sleeve, you will find two bar codes. One for the Apple Store and the other for Google Play. Situated directly below this is a sticker that includes an additional barcode plus the product code, Serial no, Colour and resistance Value Ohm 0.3Ω. To check the products authenticity just scratch to reveal.

Removing the outer sleeve, you find a black box with the silver SMOK logo printed on the top. Just lift off the cover to access the contents of the H-PRIV Kit inside.



The SMOK H-PRIV contents include the following:
1x Micro TFV4 tank
1 x SMOK H-PRIV TC box mod
1 x 0.3Ω Micro Fused Clapton Core Pre-Installed
1 x 0.25Ω Micro stainless steel dual core
1 x Replacement XL Glass Tube
1 x Tank extension adapter
1 x USB Upgrade Cable
1 x SMOK Vape Band
1x Battery Safety Card
1 x User manual

Please verify the six-month warranty period should this be included with the H-PRIV Kit before purchase. This may differ depending on your location, but I believe it to be six months from the date of purchase.

Tools Of The Trade & Safety Information

People can suffer from allergies to chemicals that may be present in the makeup of certain types of E-liquids or produced in their vapour. People can become sensitive to, or even allergic to Nickel or Titanium used in Temperature Controlled designed coils. Seek professional medical advice before using any of the products used in my reviews.

These calculators are currently under development, and the information that they contain may change at any time without notice. Please read the How It Works section for a more in-depth understanding. And never leave your device charging unattended, make sure you are using the recommended battery for your device, and always remember, SAFETY FIRST.

The H-PRIV has been thoroughly tested in Temperature mode as well as Variable Wattage mode, for its performance, features, and any dry burning issues.

The model sent is a pre-production version (Sample not for sale), so please take this into account when evaluating my comments in the conclusion.


So, here’s a quick introduction to the features and how to use this latest H-PRIV 220W from SMOK.

Attach your tank or dripper as you prefer, primed and filled with your choice of E-Liquid and press the New Fire Key five times in quick succession. You will be met with a welcome message followed by the H-PRIV 220 and current firmware version that is installed on this device followed by the word Welcome. A message on the OLED will appear asking you if this is a new coil that has been attached. Select Yes if it is, or No if you have not changed it from the last time you used it.

Use the +/- buttons to select either YES or No and press the Fire Key to confirm. The OLED will now display the main user screen and settings including the battery life, Wattage or Temperature depending on which option you have chosen to use based on the attached coil. The resistance of the attached coil, voltage and the ramp up time is also displayed.

Use the two silver buttons situated below the OLED screen to increase or decrease the power or temperature values.

Wattage Mode

With an extremely impressive range of 6 watts, all the way up to a massive 220 watts firing down to 0.1Ω’s and up to 3Ω’s the dedicated sub-ohm vaper has plenty of power settings to choose from!

Temperature Mode

Temperature Control mode operates between 200°F (100°C) and 600°F (315°C) You have a choice of three sub menus when Temperature Mode has been selected.

  1. Strength: Soft-Min-Normal-Hard-Max
  2. Coil TC-Ni Single Coil (SC) Dual Coil (DC)
  3. Adjustment of the pre-set Coefficient Value can be changed here too.


I have also included a breakdown of the four top tier menus and the functionality of each one, plus the sub menus structures where applicable.

To access the menus, press the new Fire Key three times in quick succession and then once more to circle through each of these four available options to you.

Once you have found the option you wish to adjust, wait for a few seconds to enter that particular menu, or wait a further few seconds if you are wishing to access a sub menu below it. You can also toggle through the four options by using the two silver buttons situated just below the OLED screen as well.

A more detailed description of the menu functions can be found in the included user manual.

Options Menu

To access the options menu as I said just press the fire button three times in quick succession.

Option1 (Mode)

You can select to operate the device in either Wattage Mode, Temp mode, or Memory mode.

Wattage mode allows you to set the ramp up time between Min, Soft, Norm, Hard, or Max.

Temp Mode: allows you to set the ramp up time between Min, Soft, Norm, Hard, or Max also. There are two additional sub-menus which will allow you to set the type of coil you are using.

Coil: Ni-Ti-SS and the adjustment of the Coefficient value. After selecting Temp Mode pause for three seconds for each one of the additional menus to appear on the OLED screen.

Memory Mode: will also allow you to set the ramp up time between Min, Soft, Norm, Hard, or Max.

You can also set the Memory between 1 and 16 each having a pre-set value attached to it. These range from 10W all the way up to 220W. For more detailed description on this consult the user manual.

Option 2 (Puffs)

Here you have the ability to set a number of puffs. It is set to never by default but you can adjust this using the silver keys below the OLED screen to increase or decrease the amount you require that best suits you.

Option 3 Settings

Settings contain three menu options.

The First: is for Screen Time, followed by Screen Lock, then the Contrast ratio, the Screen Direction/orientation, Set the local Time, Adjust the initial Ohm, and finally the Download. A detailed description can be found in the user manual for each one.

The second: Stealth Mode. You can Stealth Mode on or off from here.

The third: Screen Time. You can increase or decrease the time the OLED display remains illuminated.

Option 4 Power

You can turn the device off from here You are presented with two options On or Off.

Useful Shortcuts 

By holding down the fire button and the up button you can take a shortcut to access the wattage and Temp mode display and switch between your preferred ways of operation.

Once you have set your desired Wattage or Temperature, hold down the up & down buttons simultaneously and the pre-set value you have set will be locked. To unlock for further adjustments to be applied simply hold down the up and down buttons once again.

The H-PRIV also has a built in overall locking feature that can be turned on or off by pressing the fire button x5 in quick succession to prevent you from accidentally firing the device.


So, to wrap up this review of the H-PRIV 220W box mod kit let’s start with the tank and work our way down.

SMOK’s Micro TFV4 atomizer fits in nicely with its 2.5ml size This can be increased to 3.5ml by using the replacement and larger glass tube that is included in the kit.

SMOK also offers various types of heating cores. A purposely constructed Sub-ohm edition which includes 0.3Ω Micro CLP2 Core, plus a 0.25Ω Micro STC2 Core. A flavour edition which includes a 1.8Ω Micro MTL Core, a 1.2Ω Micro MTL Core, plus a 0.6Ω Micro CLP2 Core.

There are also two dedicated temperature control editions as well that include a 0.1 Ω Micro Ni200 Core, plus an RBA edition that includes a Micro R2 and Micro RCA. For more details on these visit the Micro TFV4 Family.


More akin to the X Cube Mini than the X Cube ll, but producing an output of 220W instead of 75W the H-PRIV device itself is a visually impressive looking box mod that incorporates a futuristic looking Red Triangle firing mechanism that adds to its visually striking appearance.

The top plate houses a flush mounting 510 connector plus the Clear bright OLED screen with two silver input buttons (+/-) situated just below. This makes viewing and adjusting the settings very easy to achieve. And with the ability to adjust the contrast and screen orientation SMOK have made the user interface as friendly and accessible as possible.

The body of the device is solid and most importantly comfortable to hold. The clever re-design of the triangular shaped firing mechanism is not only aesthetically pleasing but functions very well for this type of design and feels more solid than its predecessor.

Improvement has been made to the battery compartments door offering better connectivity through the inclusion of 24 caret gold plated Positive & Negative terminals which should help in increasing the electrical conductivity.

The cover is now made from plastic which will make it not only lighter than earlier versions but provides better insulation. And with no fewer than eight venting holes placed in the battery door, heat dissipation can be handled far more effectively as well.

SMOK have also included a visual reference to the battery installation with plus and minus symbols added to avoid any confusion.

Overall this has been a very pleasant vaping experience for me personally. Depending on whether you happen to be cloud enthusiast or a flavour chaser or indeed both SMOK’s endless choice of coils should be able to meet your demands very comfortably.

And with the built-in technology, accurate temperature sensing capabilities, and huge output this could very well be the choice for you.

Check with your local B&M for a price or a reputable online store.
