The Smok RPM 4 pod kit offers a compact and simpler approach to sub ohm vaping. Powered by a larger 1650mAh built-in battery, it’s still a small kit that will fit comfortably in your pocket. Capable of a 5 - 60W output range, it can be used for DTL (Direct To Lung) vaping with the coils included, there are also MTL coils available separately. You can expect up to a day’s worth of vaping when fully charged, plus the kit comes with two refillable pods and both a Smok RPM coil and an LP2 coil to get you started.
A simplified user interface makes first-time set-up and any future adjustments very simple, while the 0.96 inch screen clearly displays important information about battery life, power level and coil resistance. Although this kit can be used for sub ohm vaping straight out of the box, by installing one of the compatible MTL coils from the RPM coil range or LP2 coil range, you’ll experience a vape that feels closer to a cigarette.
Both versions of the RPM 4 pod are very easy to fill, featuring a side filling port and can be filled with up to 2ml of e-liquid. Thanks to the wide range of coils on offer, you’ll be able to pair these pods with High PG, 50/50 and high VG e-liquid. The included coils will work best with high VG e-liquid. Featuring mesh builds, the LP2 0.23 Ohm coil and classic RPM 0.4 Ohm coil can heat more e-liquid faster to deliver better flavour and more vapour.

Battery dies really quickly, pod is a nightmare to refill, gives a really weak feeling and wet vape that coats your mouth in liquid when using certain juices, and the leaking is ridiculous. The way the coils are made leaves a huge gap in the bottom around the ill-fitting rubber o-ring, and as liquid soaks in to the cotton it just drips through the bottom of the coil into the socket. Fair enough it doesn't leak all over your hands or pocket, but when you take the pod out to check how much juice you have left it's often just filled with liquid. The TPD 2ml pods are way too small for how much juice this can consume, too.
In short, constant refilling, constant recharging, constantly washing liquid out of your mouth with water, constantly cleaning out the socket.

I was a massive fan of the first Smok RPM, this forth iteration looks nice, but unfortunately the airflow kinda ruins the experience of it...using the RPM coils seemed waaay better on the original device that had a fixed airflow slot! A shame, don't really use this anymore, the IPX80 is a better device by far!
This is my first cap mod and I can’t be more pleased. I’ve had this for several months and it’s great. Feels good in the hand and good size. It has a reasonable amount of weight to it and feel like good quality - I should know I’ve dropped it couple times.
The only downside is the lack of instructions but there’s endless amounts of videos on YouTube. I registered is right away with the guarantee but I doubt it will ever need to be used.
Good for beginners. Battery life seems ok so far, good build quality - doesn’t feel cheap and small enough to fit in your pocket.
Easy to fill with juice
By Anonymous from Stoke
By no means is this the perfect vape kit, however it is really good for beginners/intermediate users and will allow for different vaping methods depending on whether you MTL or DL vape.
Allows for different types of coils and different vaping styles, you can use pretty much any juice with this kit!
THE BATTERY, I can literally charge this once every two days and the battery has never fully depleted on me, even with me being quite a heavy vaper.
The build quality and design is also very nice, it doesn't feel cheap and it can easily fit in your pocket.
The button is VERY responsive and you can easily press the button whilst carrying it around, however if you press the button three times it will lock the power meaning this won't be an issue; however I always forget to press the button.
Whilst the pod is very easy to fill, it can be difficult to see how full the pod is, leading to putting too much juice in.
Had a rpm40 which sadly gave up the right to vape, looked about to find a similar vape and up poped the rpm4, pretty much the same as the 40, but just refined a bit more

I've had the RPM4 for over 6 months now and it is the only vape that has not only lasted but also allowed me to try a range of coils and their corresponding e-juice. It's versatility is really great, where you have an RPM pod and an LP2 pod giving you many options in terms of MTL and PG/VG ratios. The battery is great and rather simple to use. The fact that it goes to 60 watts, at least for me isn't a selling point since most coils I use require a maximum of 25 watts. But this helps in the sense that the battery accommodates mt low wattage use. Just be sure to follow the instructions when charcging and don't use laptop USB-C chargers as that effects the battery in the long term.
I was previously using the SMOK rmp40 I thought it was time to get a upgrade. I was instantly drawn to this model as it similar but with some new features. I like that this model has adjustable airflow and the new lp2 coils give great flavour and bigger clouds. Overall I think that this is a great little device at a very reasonable price.

An update from my previous review, having reduced to 6mg 50/50 Nic Salts this turned into a problem. Whatever I did with it after a few puffs the coil flooded and started spitting and gurgling. I think I was sucking on it too much due to what seems like reduced cloud volume.
I tried several new coils and pods with no success. I also changed to 70VG and this seemed a bit better but would do the same thing after half a dozen or so puffs. I gave up with it and went back to the Caliburn G which was fine with the lower nicotine at both 50/50 and 70VG. Even when I was more used to the reduced nicotine in the Caliburn I couldn't seem to master the Smok.
I have since upgraded to Innokin Z80 with Zenith II tank which is great and I now wish I hadn't bothered with the Smok. Might just be me but if you are planning on reducing nicotine levels you might find you experience the same problem.

Ive got quite a collection of vape kits this one is so easy to use i think being square makes it so much better to hold. The mouth piece is deffinately much better than the little round ones which are on most pod vape kits. Filling is easy enough too do i wish we had the 5 mil tanks will look around to see if i can find some. No leaks good solid connection for the pod, i like that you can change screen colour, great taste not sure yet how long coils last? Only bad thing for me is you have to charge it laying down so always remove pod just incase it leaks other wise its perfect for me.

I've been vaping a few months having started out on a Caliburn G and thought I'd try something a bit more powerful to aid reducing nicotine. I've already dropped from 20mg to 10mg and although I haven't tried going to 6mg yet I do think this will make it easier than with the Caliburn.
Have a look at online video reviews, the ones I watched accurately describe. They do however seem to focus on DTL rather than MTL use, perhaps because it doesn't come packaged with a specific MTL coil.
VC recommended the Nord but I chose this one as it has clear pods and you can reset the puff count which is handy to check usage (a review said you can't on the Nord but I can't be certain about that). Note the time displays the length of the last draw only and not accumulative.
I tended to use the Caliburn on auto draw without pressing the button press but I had instant success pressing the button on the RPM, not like when I first tried vaping and gave up with a button device a few years ago. For me auto draw was a good feature when I first swapped to vaping but not something I now miss.
I got the black leather one and build quality seems good and its comfortable to hold and not too big, its similar to 2x Caliburn Gs stuck together but is a bit shorter and doesn't seem overly large in the hand or pocket. The drip tip is bigger but I didn't really notice a difference.
I'm using the optional RPM 0.8 MTL coils at 16W with 50/50 10mg Nic Salts.
I wasn't sure what to expect in comparison to the Caliburn, it doesn't blow you away as being miles better but its definitely a thicker inhale and has a fuller flavour and is more enjoyable.
I've found the draw feels just a tad too restrictive with the air vent fully closed so I have it open about a quarter. That's my personal preference and it could be easily vaped with this coil with the airflow in any position. Throat hit and smoothness of the couple of my regular ADV flavours I've tried so far seems very similar to the Caliburn, perhaps a little harsher which I like but can be made smoother if I open up the air further.
Turning the wattage down to say 12W seems to produce similar flavour but it takes a fraction longer to get going and produces less vapour although draws better at this wattage with the air wide open. I'm not sure if slightly reduced wattage will significantly extend coil life much or use less juice but neither is a concern for me. I'm perhaps using a fraction more juice than with the Caliburn but likely because the new vape novelty hasn't worn off yet and its not a difference to write home about.
The pods come with silicone bung to make them the regulation 2ml. I tried getting it out of the LP2 pod but ended up scratching the inside where the top of the coil seals so have ordered some 5ml bung free ones from Hong Kong. Certainly not as easy to remove as it looks in videos of the Nord pod, you might have success with removing it but I wouldn't bank on it.
Zero leaks and easy to fill although the stupid bung makes it harder to see liquid level. After 3 days of vaping theres a tiny bit of condensation under the coil but a quick wipe with a tissue gets rid of that.
There is a good choice of coils and there should be something to suit all MTL preferences. I may try 70/30 ratio with the RPM 0.3 MTL mesh coil at some stage but other than using short fills I don't really see the advantage as I don't want increased cloud. Depending how I go I might also think about trying the LP2 0.6 MTL coil with reduced nicotine. I won't bother with the higher above zero ohm ones.
Battery life is very good and lasts well over a day for me, I haven't run it down to flat but in a day with 350 puffs averaging around 2.5 to 3 seconds and its used 50%. (reportedly theres around 300 puffs on 20 smokes?)
It takes about 30 mins to recharge from 50% and has a handy time estimate on screen when you plug it in which seems accurate to a few minutes. Higher wattage and longer draw would obviously affect that though. Only slight thing which could be improved is that the USB-C port is on the bottom rather than the side so its best to remove the pod for charging.
This is now my ADV but I like to vary flavours through the day and trying new ones so I will still use my Caliburn pods for lesser vaped and strong flavours such as cherry or artic roll. I used to buy an occasional disposable to supplement the Caliburn if out and about for long periods, I will now use the Caliburn to supplement the RPM. What I'm trying to say is with an upgrade the starter kit still has a use.
I don't have a lot to compare against but I think its very good and am pleased. Certainly I can recommend as a next step if you are looking to progress from a starter kit.
