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.

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.
