Smok RPM 4 Style and also Construct Quality

I got the Smok RPM 4 in the most effective colour there is – Cyan Pink!

If I can select any type of in the line-up this would certainly have been the one – so I more than the moon!

rpm 4 v rpm lite
Left = RPM Lite. Right = RPM 4

The product packaging is excellent and also whatever showed up in sparkly problem.

Also the direction brochure is fantastic – all these web pages (both sides published) remain in English language just – so you can see just how detailed the guidelines are!

In some sets a brochure this dimension provides for all the languages ever before recognized to man with just 3 sentences for each and every language – Bravo Smok!

rpm 4 instructions

On small drawback is fairly a brief USB Kind C cord at 50cm long – yet I have actually seen a great deal much shorter so this is still ok-ish.

Smok RPM 4 Mod

Simply WOW! I can rarely share just how stunning this tool is!

The text has a metal feeling with tiny indents as a pattern to provide appearance.

rpm 4 texture

The colour at the base begins at a Cyan blue metal and also carefully discolors right into an actually appealing metal pink – Definitely magnificent.

Also much better than the text coating are the trim panels!

rpm 4 crop views

These are an extremely refined stunning rainbow steel coating and also are discovered on the base of the mod, the front control board, around the 2 side air movement inlets and also a panel on the back of the mod.

The colour modification is excellent and also simply makes this mod beam with charm.

rpm 4 rear view

All the installations and also adapters really feel outright top-notch – not a rickety or unsteady little bit visible.

A Tiny “Smok” logo design gets on the front of the mod and also on the back rainbow panel is the RPM 4 logo design and also CE markings etc.

rpm 4 front view

The base houses the USB Kind C port and also it functions flawlessly together with some message claiming “Designed By Smok” simply in instance you had actually neglected that made your package.

Plus there seems 3 tiny battery airing vent openings.

rpm 4 base

The capsule will just glide in in 2 methods – 2 lugs on the side of the capsule line up with 2 eliminate in the mod body. The capsule will certainly likewise fit if you turn it 180°.

rpm 4 pod locator

A magnetic link safeguards the capsule in securely – you can also evaluate this by just mounting the capsule half means and also view the magnet draw it in like magic right into the mod.

rpm 4 slider

An air flow slide button lies on the back of the mod, it is a little bit tough to relocate as it is a little tight and also a little bit recessed so it will certainly require a finger nail or comparable execute to relocate.

Nonetheless, the bright side is when it has actually been adapted to your choice it is not likely to call for relocating once again.

Show Panel & Controls

The front of the mod includes the display screen panel and also primary tool controls.

On top is the square fire switch, which has actually been placed well and also is receptive with a plain click audio.

rpm 4 display panel

Listed Below that is the beautiful TFT 0.96in colour display which is clear and also fairly intense.

On top of the display screen is the battery information – a symbol shows pictorially the cost staying plus a percent is presented in message alongside it – I such as having both of these.

rpm 4 display

Listed Below that is your power level setup – from 5-60W with the W icon alongside it.

Over the power level icon is the “lock” icon – a lock which will certainly be presented in red if the fire or modification switches are secured.

Beneath that is the coil resistance with a weird coil design icon and also to the right of that is the voltage and also a little trigger icon.

The voltage will just show when the fire switch is pushed and also is not flexible.

RPM 4 Purple and also Environment-friendly display styles

The last 2 lines on the display are committed to the smoke counter and also vape time.

The timer resets whenever you push the fire switch. I am not exactly sure truly if this feature is of any type of usage as the only occurrence where vape time is a problem is if you hold the fire switch down for over 8 secs and also the tool will certainly eliminate to stop getting too hot.

Following are the backwards and forwards modification switches these behave and also clicky and also although tiny are simple to utilize.

rpm 4 button side view

I like the reality you can secure the fire switch and also power level switches individually – some gadgets just secure one or the various other. You can do simply one or both on this.

Smok RPM 4 Sheath

The very best function of the skins are the clear home windows on top to provide a great indicator of fluid degree.

Several of the capsule is still hidden within the mod yet if you tip the mod you can go by this tiny home window just how high the fluid degree is.

rpm 4 liquid level

You obtain 2 skins in the package – the LP2 suitable capsule and also the RPM suitable capsule.

The fill port cover has the name of the capsule marked on.

The cover is fairly simple to raise and also you can turn it off the beaten track to make loading simpler.

Yet like the RPM Lite I do locate it tough to shut the capsule as it has fairly a limited plug suit the fill port opening.

rpm 4 fill port

Dimension sensible the fill port is rather conventional I have actually come across no concerns utilizing spout containers yet a dropper applicator may be tough to utilize.

Complying With on from the earlier RPM sets this has the “Duck Bill” design mouth piece which is truly comfy in the mouth and also I discovered it fantastic on the initial Nord package.

This is simply a little bigger than the mouth piece you would certainly locate on the Nord yet still fantastic to utilize.

The capsule base houses the take out coil and also the magnets to protect the capsule securely in the mod.

rpm 4 pod bases

One concern I did locate was that the RPM capsule was a little bit tough to press right into the mod completely.

I don’t recognize why yet it kind of quit with a void in between the capsule and also the mod.

You can press it in additional yet took even more initiative than the LP2 capsule. Likewise it is a great deal tighter to eliminate than the LP2 capsule.

Smok RPM 4 Coil Options

The package includes 2 various skins suitable with various coil varieties…

rpm 4 pod types

  • RPM4 LP2 capsule – this makes use of the brand-new variety of LP2 coils
  • RPM4 RPM capsule – this makes use of the existing variety of RPM coils suitable with various other RPM gadgets consisting of the RPM array and also some later Nord gadgets.

There are 2 various LP2 coils readily available a 0.23ohm fit together coil which is consisted of in the package and also a 0.6ohm twin cable coil which is readily available independently.

rpm4 lp2 coils

When it pertains to the RPM coils there are great deals to select from – you obtain the 0.4ohm RPM Mesh coil with the package.

Smok RPM 4 Flying Start Overview

The package shows up with the LP2 capsule set up.

Nonetheless there are a couple of even more actions to take in the past you can rise and also running – I will certainly order you by the hand and also overview you with them carefully I guarantee!


First of all the coil is secured by a protecting sticker label – this is to stop the tool shooting mistakenly in the product packaging.

Likewise ensure to load the capsule with e-liquid and also entrust to represent 10 mins prior to eliminating this sticker label to stop melting the coil out and also knackering it up absolutely.

Eliminate the sticker label – mount the capsule right into the tool and also comply with the remainder of the guidelines listed below to start!

  • Modification style colour = press Fire and also the UP modification switch to cycle with the style colours. Quit when you have actually gotten to the colour you desire.
  • Air movement modification = action the gliding button to open up or shut the air movement as needed.airflow


  • Reduced battery – Show will certainly reveal “Battery Low” and also you will certainly require to reenergize the battery.
  • Brief circuit – Show will certainly reveal “Atomiser Short” – change coil and also look for any type of leakages or damages
  • No Atomiser – Show will certainly reveal “No Atomiser” and also you can still make changes etc yet the tool will certainly not discharge up until the capsule and also coil have actually been set up properly. If this shows up and also the capsule is set up inspect the link to the coil and also capsule or change the coil.
  • Resistance limitations – if a coil over the 2.5ohm resistance restriction is set up the display screen will certainly reveal “Ohms too High”. If a coil listed below the 0.2ohm restriction is set up the display screen will certainly reveal “Ohms too Low”. In both instances change the coil which has a resistance which is within these limitations.
  • In time – there is an 8 2nd fire cut-out and also “Time Over” will certainly be presented and also the fire procedure will certainly quit. This is to stop getting too hot and also unintended switch pushing.
  • Heat – Show will certainly reveal “PCBA Too Hot” and also the heat security begins to stop procedure up until the tool has actually cooled off.
  • Power Secured – unlock the fire switch by pushing it 3 times.
  • Power level Locked – open the power level modification by pushing the backwards and forwards modification switches at the very same time.

Exactly How To Bill The Battery

  • Making use of the consisted of USB C cord link the tiny end right into the USB port on the mod. charging port
  • Attach the big end of the cord right into an appropriate USB electrical outlet.
  • The display will certainly show the progression and also approximate time staying up until complete cost.charging screen
  • The display screen will certainly head out when completely billed.

Utilizing a 2.4A charging plug it required to around 1 hr and also 2 mins to bill. Originally the display screen informed me it would certainly be 59 minutes to completely bill – so this is rather well thought!

Although my billing outcome was 2.4A – limit input for the mod is 1.5A. I believe I am right in claiming the tool will just attract the existing it can anyhow?

Exactly How To Load

  • Eliminate the capsule by drawing it out of the mod. There is some resistance as a result of the magnetic keeping system.
  • Transform the capsule on its side with the fill port cover dealing with up.
  • open fill portMaking use of a finger nail or comparable prise up the fill port cover and also turn it off the beaten track.
  • Include e-liquid to the fill port whilst observing the fluid degree with the side of the capsule.filling
  • Change the port cover securely and also clean away any type of splilling.
  • If this is the initial fill or when utilizing a brand-new coil leave the capsule to represent 10 mins to ensure the e-liquid has actually completely saturated right into the wicking in the coil.
  • Breathe in on the mouth piece 2 or 3 times prior to pushing the fire switch to simply ensure the coil is filled with fluid.

Exactly How To Change the Coil

Exactly How Does the Smok RPM 4 Perform?

As this is a DTL (Straight To Lung) / RDL (Limited Straight Lung) package I will certainly be utilizing reduced pure nicotine and also greater VG e-liquid.

I am utilizing my old favorite Stika Bombz Fruit Salad. This has freebase pure nicotine and also is an 80/20 PG/VG e-liquid.

It is likewise rather kind to coils I have actually discovered throughout the years.

If any one of these terms more than your head – have a read of our helpful overviews listed below!

LP2 Harmonized 0.23ohm DL Coil

This has a preferred power score of 20-45W.

I began at 25W with the air movement in the extra limited location and also currently simply wow!

From the initial vape the flavour blew me away!

The vape is fairly cozy also at the reduced end of the power limitations yet a little much less vapour than I would certainly anticipate from this e-liquid..

As Much As 30W and also this has actually heated up a lot more and also I am needing to take much shorter vapes currently!

At 35W this is warmer still yet the cloud outcome has actually raised. I am depressing that being a MTL vaper nowadays I can’t take the substantial inhales I utilized to!

I obtained endure and also rose to 40W and also even more of the very same. The flavour outcome has actually ended up being extra extreme with various subtleties of flavours coming with. Likewise the vapour outcome has actually raised widely.

At 40W I likewise opened the air movement completely and also the experience came to be a lot more extreme.

I will certainly claim this is fairly a loud vape – not unstable yet you can listen to the air movement and also also without vaping with the fire switch pushed you can listen to the coil shooting.

This really feels means extra effective than 40W! It resembles utilizing a big mesh below ohm storage tank at 70W

Fairly unbelievable – I like it!

I discovered myself knocking the power to 30W and also establishing the air movement simply a little listed below completely open for a tiny constraint. In completely limited the flavour is excellent yet the clouds experience and also it does come to be a little bit also cozy to vape. Nonetheless with the air movement folded the heat makes it seem like you are vaping at 50W as opposed to merely 25W!

Having actually vaped 5ml currently and also on my 2nd fill out – the flavour is still stunning and also navigated 150 smokes from 5ml.

RPM Mesh 0.4ohm Coil

This has a preferred power score of 25W.

I utilized the very same e-liquid as utilized on the LP2 capsule and also began at 25W – which is the only referral on the Smok site.

Once again which ever before air movement setup you utilize the flavour is punching!

The vapour is a great deal thicker than the LP2 coil I believe with the air movement completely open.

At 25W I discovered the vape was a little cooler than it was with the LP2 coil and also I had the ability to take longer breathes in – they were extra comfy.

It is a much drier vape than the LP2 coil – yet the flavour is solid and also the throat hit is certainly there. Yet I do like the wet (urgh awful word!) vapour from the various other coil / capsule combination.

Likewise the outcome really feels a great deal reduced yet smoother – I did a straight contrast switching in between both skins at 25W – the LP2 had even more of a kick and also a snap, whereas the RPM was a great deal smoother and also calmer.

Both coils truly have a great deal of flavour taking place – however, for my choice the LP2 coil matched me much better.

The RPM coil is a great deal even more polished, smooth, amazing and also gent like whereas the LP2 was a little bit extra intense.

Air Flow

With the LP2 coil in the completely shut (even more constraint) setup there is certainly a great deal of constraint.

I wouldn’t claim fairly MTL though! Likewise completely shut this does impact the vapour outcome yet the flavour is still rather legendary!

In the completely open setup this is extremely ventilated with 1 being completely shut and also 10 resembling breathing this has to do with 8-9. So the extremely smallest of constraint. The bright side is that in this establishing the flavour and also clouds are truly at their optimum.

With the RPM coil and also capsule the completely open air movement was a little extra limited – around regarding an 8 and also the completely shut was a limited DTL vape – still not shut sufficient for MTL.

Smok RPM 4 Mod Efficiency

I have actually had no concerns in all with the efficiency and also also been truly stunned at just how well the battery lasted.

Likewise the construct top quality was unexpected!

The rate of shooting was immediate without delays and also the power outcome appeared to be consistent right to 3% battery cost staying.

Something that did truly amaze me was just how affordable this was with e-liquid – I did obtain the 5ml variation – yet however I overcame 150 smokes from one storage tank complete.

I have actually had no concerns in all, no leakages or breakdowns, there was a mild quantity of e-liquid in the mod link location from the fill port cover.

I did battle to obtain the cover to enter completely – as it has an actually limited “Plug” seal and also I believe some fluid might have leaked out as I was fannying regarding attempting to shut the cover.

Smok RPM 4 Battery Life

Normally I time the length of time the battery lasts with normal vaping – yet this is so variable with various vaping designs and also your very own choice.

So when a tool has a smoke counter I will certainly utilize the smoke matter rather. This is likewise fairly variable as some individuals do take longer breathes in than others and also this will certainly certainly impact the battery life.

Anyhow as an overview I obtained 275 smokes with the LP2 coil at 30W. This has the 5ml capsule which was primarily 1.5 capsule fulls (approx 7.5ml) of e-liquid to one cost.

I didn’t discover any type of decrease in power or efficiency up until the battery display screen revealed 3% battery staying, after that I obtained the “Battery Low” message if I vaped longer than a 2nd.


  • The most beautiful capsule package I have actually ever before seen – stunning outlining on the panels also!
  • Construct top quality is rather unbelievable – specifically for a Smok tool in the reduced cost brace also!
  • Suitable with RPM and also brand-new LP2 coil varieties – plenty to select from.
  • LP2 coil provides the outcome at 40W of a big below ohm storage tank at 70W! Fairly unexpected. This coil also executes at the reduced power of 25W!
  • RPM provides a smoother, quieter vape
  • Easy to see e-liquid degree with clear home window location in capsule.
  • Cost-effective e-liquid use
  • No leakages or breakdowns


  • Load port can be a little bit fiddly
  • Tough to inform the skins apart if you had view concerns – the writing is not extremely clear on the fill port covers, a colour code or comparable could enhance this.
  • Can be a little bit tough to hold the coil base for coil elimination – if you haven’t any type of finger nails you will certainly require something to prise it out with – not suitable if you are out and also around.
  • Vaping is fairly loud on the LP2 coil – from the air movement to the real sound of the coil being discharged.
  • RPM capsule was fairly a limited fit and also took even more initiative to eliminate and also mount.

Last Evaluation Decision

I dropped definitely head over heels with this package the 2nd I opened it – truly truly perfectly created and also ended up.

It is that excellent that I will certainly be buying a few of the LP2 coils as I truly appreciate this reduced power DTL experience and also just how little e-liquid this makes use of in contrast with a big below ohm storage tank.

I believe any type of DTL vaper would certainly appreciate this experience, yet if you are somebody that requires high pure nicotine and also throat hit – this is not truly a package for you.

For those individuals you are much better off looking extra in the direction of the RPM Lite or the Nord / Novo array. And even chucking the 0.8ohm DC RPM coil in this package.

This is not a big cloud chucking power beast whatsoever – yet any type of vaper that suches as greater VG e-liquid flavour can gladly take this out with them for a couple of hrs and also take pleasure in the flavour and also heat you obtain.

A Number Of Niggly Issues…

I have a couple of small niggles regarding points like the fill port cover being fiddly and also informing the skins apart. Yet these are extra niggly issues than real bargain breakers.

Likewise as this is a DTL tool I have actually not utilized this far from house – I am an MTL vaper that requires some much heavier pure nicotine when I am out and also around.

So for this testimonial the package has actually just been utilized rested at a workdesk or lounging in your home – it hasn’t had the “handbag” or “rolling around the car” experience my gadgets normally need to deal with!

I constantly rank the item I have in front of me and also in regards to vaping satisfaction this is a charm.

I know just how much the top quality can differ with Smok gadgets – I have my very own experiences of this unfortunately.

Yet in my hands the RPM 4 package I am utilizing is an outright charm which discards way extra flavour than I anticipated.

I like it – do you?
