Smok X Priv Kit Review


When I first saw pictures of this mod, I knew that I wanted to try it out. It just looked like a really nice form factor as well as a very small form factor for a dual battery mod. Taking it out of the box, my initial impressions were right on. This is a really nice mod with a great form factor and it’s extremely small for a dual battery mod. It’s not Eleaf Invoke small but it’s definitely a nice compact dual 18650 mod. I also love the fact that almost the whole front of it is all screen. Let’s load some batteries in it, juice up the new Prince tank, and see how it actually performs.

Starting on the top side of the mod, we have a really nice 510 connection. There is a stainless steel plate around the 510 connection and it is milled into the mod so it does sit flush on the top plate. If the screen is facing you, the 510 connection is on the left side of the mod. I really wish Smok would have centered the 510 connection on the X-Priv. The 510 pin is gold-plated and spring-loaded. It has a really stiff spring and a short throw. The threading around the 510 pin is nice and smooth and so far, all of my atomizers have sat flush on it. You can get up to a 28 mm atomizer on here with a very slight overhang. Actually, because of the beveled edges, a 28mm atomizer does not look too bad. 25 mm atomizers will fit with no overhang at all.

With the screen facing you, on the left side of the mod is where you will find the firing bar. The firing bar is something that Smok made famous and they have basically perfected it. You can hit the bar anywhere from the middle of it, all the way up to the top in order to fire the mod. The lower you press on the bar, the harder it is to fire. The firing bar has a very nice, clicky feel to it. It is well done and it is also distinctive from the other side of the mod. I have seen other mods that have this type of firing bar and it’s hard to tell the difference at first sight which side of the mod the firing bar is actually located on. That is not the case with the X-Priv. There are some clear spaces that indicate that the left side of the mod is where the firing bar is located.

On the backside of the mod is where you will find the battery door. The exterior of the battery door has a beautiful honeycomb design on it. Towards the bottom of the battery door, there is also some Smok branding. The branding is subtle and not really obnoxious at all. On the bottom of the battery door, there is a slot that you can get your fingernail into in order to lift the battery door. Once you lift the battery door up, on the interior, you will see for strong magnets in each corner of the battery door. The battery door is also lined with some sort of plastic for safety, just in case one of your battery wraps has a tear.

The battery tray is very nicely done. Not only does it have clear battery indicator markings but Smok decided to do them in white. They contrast beautifully against the black battery tray and they are very easy to see. Well done, Smok! When you load the batteries in the mod, both batteries go in positive side down. Just like you would in a parallel mech mod but because the battery tray is wired for series, you don’t have to worry about all that mech mod stuff. I like the fact that Smok did this and I think, it just makes things easier when people are putting their batteries in the same way. I wish more manufacturers would do this, just for the sake of simplicity.

Of course, in the four corners of the battery tray, there are four magnets that correspond with the four magnets on the battery door. There are also four star screws that hold your battery tray in place. Smok also included a battery strap in order to make it easier for you to get your batteries out of the mod. I have not experienced any battery rattle or battery door rattle. The bottom battery contacts are gold plated and spring loaded. The top battery contacts are gold plated and button style. Overall, it’s a very well done battery compartment.

Back on the front side of the mod, we have the screen and above the screen, there is some Smok branding. The X-Priv has a massive 2-inch HD color screen that is just drop dead gorgeous. I just can’t say enough good things about this screen. It is extremely colorful and well laid out. I love the size of it and I love the way it looks while you are vaping on this mod. It is just fantastic. On the screen, you will be able to see two separate battery meters labeled A and B, wattage, temperature, preheat, resistance, voltage, amount of puffs, and duration of puff. You are also able to change the colors on the screen. It’s just an extremely well laid out screen that is bright and you can see it in every lighting condition. Bravo, Smok!

Below the screen, on the right hand side of the mod, is where the up and down buttons are located. The up and down buttons have a rectangular shape to them but they also have a nice curve to them that goes along with the actual curve of the mod. Of course, the up button is located higher than the down button. The X-Priv does scroll in .1 watt increments. I would like to see more mod makers move to a 1-watt scroll.

To the left of the up and down buttons is where the charge update port is located. I could not find any information as to what rate the batteries charge at internally but I will say that Smok did include a really nice USB cable in this kit. If I do find that information, I will update this review. For me, it’s really not a big deal because I really don’t recommend that you charge dual batteries internally. It is a nice feature to have 2 amp charging for those times you are on the go but I can not confirm that this mod charges at 2 amps.

Focus On For More Vape Start Kit.


In this kit, you get the new Smok Prince tank. I tend to think of this tank as a really nice compromise between the TFV12 Cloud Beast King and the Big Baby Beast. For me, it provides a vape that is right in the middle of those two tanks. It also takes its own family of coils that have been developed for the tank. Neither Baby Beast nor TFV12 Cloud Beast coils will fit in this tank. You get two different coils in this kit but there are four available as of this writing as well as an RBA section. I’m sure, more are on the way but I do wish they would have included the RBA section in the kit. To make the RBA a separate purchase is just ridiculous.

Starting at the top, we do have a beautiful cobra style drip tip that is made to match the color of the tank. Smok is calling it that because it has a pattern on it that looks like a snake skin. In all reality, it’s just a dressed up, proprietary, Smok drip tip but I have to give them credit because it does look very nice and it matches up beautifully with the tank. It is also very comfortable and I have enjoyed using it. Smok also has glow in the dark Cobra DT’s available as a separate purchase.

The Prince tank has that slide-out, top-fill feature that Smok has made famous. This one has a locking mechanism to it that I really like. Instead of pushing down and swinging the top cap out, on this version of Smok’s top fill, there is a button on the side that you press in order to release the top cap. Once the button is pressed, you can swing the top cap out and fill up your tank. It’s a really nice improvement and it works really well.

The top cap opens really wide and it reveals a white gasket. The gasket goes around your chimney and your fill port opening. The fill port opening is the shape of a Tic Tac and it will accommodate most bottles including the bullnose type of juice bottles. You do have to be careful with the bullnose type of juice bottle but it is possible to fill the tank with them. You also get a spare gasket in your spare parts pack.

The bubble glass does come preinstalled and you do get a straight glass spare. I love the bubble glass. With the bubble glass section installed, you get a whopping 8 ml capacity. With the straight glass installed, the capacity drops down to a mind baffling 2 mls. I have no idea why anyone would want to run that glass unless they absolutely have to. I understand it’s the whole TPD compliant thing but I find the spare glass on this tank be absolutely useless, especially since I don’t live in the EU. I think Smok should have included a spare bubble glass, especially for the kits going to non EU countries.

The base of the tank is where the airflow is located. There are two cyclops style airflow slots. They are fully adjustable. The airflow is very smooth and this is quite an airy tank. There is some knurling in between the airflow slots that help you get a grip of the AFC. The AFC does have stoppers on both ends and the action on it is very smooth. Make no mistake about it, this is a DL tank. There is no way to MTL this tank at all. This is for the people that like lots of airflow and plenty of flavor. The base of the tank does measure 25 mm but with the bubble glass installed, the middle section will protrude slightly from the base.

The first coil I tried was the Q4 coil. I like this coil and I did get a really nice vape off of it. I was also surprised at the coil longevity. I had this coil in there for well over two weeks and the flavor was actually really good all the way through. In fact, I probably chucked the coil with some life still left in it because I needed to move on to the second coil for my testing in this review. I really liked vaping this coil right around 75 watts. At that wattage, I get a nice, flavorful vape and the clouds weren’t bad either. At the lower end of the coils rating, the vape was definitely anemic and less flavorful. When I tested this coil out in my Mag kit, it had a hard time keeping up on the higher end of the wattage range. That was not the case with the coil I got in the X-Priv kit. I have been running this coil a little hotter than I did on the Prince tank that was included with my Mag kit. This one seems to do a little better with the higher wattages. I have been running this one a lot closer to 80 watts and I get a much more flavorful vape. I don’t know if they improved the QC on the coils or if I just got a janky one with my Mag kit.

The next coil I tried was the T10. This coil was definitely more my style of vaping. I like to vape right around 85 watts most of the time and this coil is perfect at that wattage. I get a really nice, saturated, flavorful, cloudy vape when I vape it at 85 watts. At 60 watts, the vape is okay but it’s definitely lacking some flavor and clouds. I did push the coil up to the 100-watt limit and while it did keep up beautifully, I just don’t like to vape that high. The vape was just a little too hot for me at 100 watts. I think the sweet spot for this coil is right around 85 watts. That is exactly where you will get the best compromise of clouds and flavor with this T10 coil. Out of the two coils included in the kit, this is definitely my favorite.


I absolutely love the look and feel of this mod. Yes, I know, it really is just a box but it’s the way they did the box that makes it feel so good in your hand. They really beveled this thing out and put some nice smooth curves on it. The screen on it almost looks like a smartphone, the way they beveled out the edges of it. All the curves and all the soft edges are just fantastic on this mod. Plus, let’s not forget about that awesome screen that Smok decided to put on this mod. The screen is absolutely huge, colorful, and extremely vibrant. I would say that this is one of the best screens that I’ve seen on a mod in a while now. Just fantastic. It doesn’t look like it in the pictures but when you hold this mod in your hand, you will understand exactly what I am talking about. If they would have just centered the 510 connection on this mod, it would have been close to perfection from a form factor standpoint.

I am also extremely impressed with the paint on the X-Priv. Smok did a great job matching up the tank color to the color of the mod. The color matching job that they did is almost seamless. Everything in this kit just looks great together. The finish has been extremely durable. I have been using this mod a lot in the last month or so and this finish on it has held up just beautifully. I have had this thing in my bag, in my pocket, and I have tossed it all over the place and I have no scratches on this mod. Even the bottom of the mod where you normally get some wear and tear from putting the mod down on a table or rough surface is scratch free. The finish on it is very glossy and it has an anodized type of look to it. When it comes to the finish on this mod, they did a bang-up job on it. The X-Priv is also available in a ton of colors. Those colors include gold, blue, chrome, gunmetal, rainbow, red, and pink. If I know Smok, in a month or so, there should be even more colors available.


The proprietary board that Smok used in the X-Priv mod is one of their newest boards. When I first saw the screen, I was really excited to try it because it’s a larger version of the Mag screen. I will go over it in more detail in this section but I can tell you right now that this chipset is a very much improved chipset when compared to the older ones used in previous Smok mods.

The X-Priv has a maximum wattage output of 225 watts and a maximum voltage of 9 volts. It has a full temperature control suite that includes Ni, Ti, and SS. It has wattage adjustment capability in TC mode. It has a temperature control range of 200 to 600 degrees Fahrenheit. It can fire as low as .1 ohm in power mode and .05 ohms in TC mode. There is a TCR function available and the mod does have preheat settings that include soft, normal, and hard.


  • Click the fire bar 5 times to turn the mod on and lock the mod.

  • In the main menu system, click the fire bar quickly to advance in the menu system or hold the fire bar to advance in the sub menu system that you are currently in.
  • Once you find the screen that you want to adjust, you can use the up and down buttons to make those adjustments.
  • Quick hold the down and fire button in order to activate the shortcut and access your materials.
  • Quick hold the up and fire button to activate the shortcut and adjust your preheat.

One thing that I have always loved about Smok mods is, all their menu systems are always the same and they are very simple. If you own a Smok mod with this type of screen, this menu system is going to be extremely familiar to you. Even if you don’t own a previous version of this chipset, this is not a hard menu system to learn. It is extremely easy and very user-friendly.


I find the X-Priv mod to be pretty accurate in power mode. I’m pretty sure the X-Priv is doing the full 225 watts. If it’s not, it’s close enough for me to not be able to tell the difference. I vaped it next to my DNA and Yihi mods and I have to say that the X-Priv gave me a very comparable vape next to my DNA and Yihi mods. The X-Priv may have been a tad cooler but I’m willing to bet that most people won’t be able to tell the difference.

TC on most Smok mods has always been pretty suspect. In the past, the best case scenario is it was inconsistent and the worst case scenario was it just did not work. I reviewed quite a few of them in the past and the TC has just been terrible. While the TC on this mod is not quite up to DNA or Yihi standards, it’s definitely much improved over past Smok mods. I think Smok may be starting to take TC a little bit more seriously and you can tell they made an effort with the TC on this chipset. It’s not the greatest or the smoothest TC out there but it definitely does TC and it does have dry burn protection. I still wouldn’t consider this a truly legitimate TC board but Smok is definitely taking steps in the right direction. The TC isn’t really bad, it was just inconsistent but not nearly as inconsistent as it has been in the past. Even when it’s inconsistent, the TC, it’s still better than not being able to do TC at all, which has been my past experience with a lot Smok mods.


  • Center That 510 Connection
  • Spare Bubble Glass
  • Include The RBA SectionI just can’t believe that Smok made such a beautiful mod and they put the 510 connection on the left side. It just baffles me why they did not center that 510 connection. It would have been such an awesome form factor if they just would have centered the 510.Get rid of that spare glass. While I appreciate the fact that they did include a spare glass in the kit, I have no use for one that is only 2 mls. For me, that’s like not including a spare glass. Why not just put another bubble glass in the Box?

    Enough already with the separate purchase on the RBA sections. Smok, you really need to start including your RBA sections in your tank kits as well as your mod kits. It’s just not right that you make them a separate purchase. I don’t know why you don’t do it, you are still going to sell a ton of coils. For the people like me that like to build, we would definitely appreciate getting the RBA section.


In case you haven’t noticed, I really like this mod. I have been carrying it around with me for quite some time now and I have put a lot of juice through this kit. I like the way it looks and I love the way it feels in my hand. It vapes extremely well and I’m a big fan of this new Prince tank. The coils for it are absolutely awesome and the flavor as well as the power that you getting in this kit is just phenomenal. If you’re looking for a small, dual 18650 mod that has a great form factor and an awesome tank, this is the way to go. The X-Priv by Smok is DeucesJack approved. Pick one up, and you’ll know exactly what I am talking about.
