Select one of the following

The Smok RPM 4 is a versatile 60W pod device compatible with a choice of pods and coils to support both Mouth-to-Lung & Direct-Lung vaping styles.

  • FREE E-LIQUID (Choose when you add to basket)
  • 60W pod device
  • 1650mAh built-in battery
  • Choice of pods and coils - supports MTL & DL vaping
  • Stepless airflow control slider
  • 0.96" TFT colour screen

The Smok RPM 4 is a compact pod device that offers users versatility by supporting both Mouth-to-Lung and Direct-Lung vaping. With an adjustable output of 5 - 60W, the RPM 4 comes with a choice of pod and coil options to suit both vaping styles.

The 2ml RPM 4 pods are designed with a transparent viewing window that allows you to keep tabs on their e-liquid levels. This prevents you from running out of vape juice and also protects the coils from burning out. The pod's magnetic connection base keeps it securely connected to the device but also means it is easily removed and replaced for filling and coil changes.

The RPM 4 benefits from step-less airflow control via an easy-to-use slider. Simply dragging the slider allows you to tailor your vape between an airier or more restricted vape as well as more or less intense flavour depending on what you prefer.

The RPM 4 is powered by a built-in 1650mAh battery that should last up to a full day of use between charges. When the battery does run flat, the USB-C charging design means the device will be quickly recharged and ready to use again.

A 0.96 TFT colour screen on the body of the RPM 4 displays important data including battery life, wattage and coil resistance to help you keep tabs on your vaping. There are also a choice of screen themes that allow you to adjust your display to your preferred colour.

To suit your personal style, the Smok RPM 4 is available in 10 colour options - with a choice of regular metallic or luxury leather finishes.


The Smok RPM 4 can be used with both high VG & 50:50 e-liquids depending on the pods and coils used.

The RPM 4 works with Smok RPM 4 LP2 pods which use LP2 coils and Smok RPM 4 RPM pods which use RPM coils.

High VG E-liquid:

  • Use RPM 4 LP2 pods with LP2 0.23ohm coil (included)
  • Or RPM 4 RPM pods with RPM 0.4ohm (included) or 0.6ohm coil (not included)


50:50 E-liquid:

  • Use RPM 4 LP2 pods with LP2 0.6ohm coil (not included)
  • Use RPM 4 pods with RPM 0.3ohm, 1.0ohm or 1.2ohm coils (not included)



  • LP2 Mesh 0.23ohm DL Coil: 20 - 45W
  • RPM Mesh 0.4ohm Coil: 25W



The RPM 4 is a great device for those looking for versatility and a device that can facilitate different vaping styles.


What e-liquid can you use with the Smok RPM 4 kit?

When used with the included pods and coils, the Smok RPM 4 is best used with high VG e-liquids with a VG:PG ratio of around 70:30.

What is the difference between Mouth-to-Lung (MTL) and Direct-Lung (DL) vaping?

In Mouth-to-Lung vaping you inhale vapour and hold it in your mouth for a moment before inhaling again for the vapour to reach your lungs. In Direct-Lung vaping you inhale in one continuous breath into your lungs. See MTL v DL for more information.

Can you wash a Smok RPM 4 pod?

Yes. Remove the pod from the device, and empty out any e-liquid. Wash the pod out with warm (not boiling) water. Ensure that the pod is fully dry before using it again.

You can also clean the connections out with cotton to remove dust.

Can I charge my Smok RPM 4 overnight?

Lithium batteries should not be left unattended when charging. It is also important to use an appropriate charger, such as the Veho Plug Adaptor. For more information see our battery safety infographic.

How long does the coil last?

Coil life depends on many factors, including how long you puff for, the e-liquid you use and the wattage you use your coil at. Low resistance coils, which are used at higher wattages, will not last as long as high resistance coils.

You can extend coil life by:

  • Priming the coil before usage
  • Using e-liquid with the right VG:PG ratios
  • Not going above the recommended wattage
  • Topping up your tank so that the coil never dries out


With care, the included 0.23ohm coil should last several days while the 0.4ohm coil should last up to a week.

Product Care

Follow these simple steps to get the most out of your vape kit.

  • For refillable devices, allow e-liquid to soak into the coil for at least five minutes before using the device.
  • Always keep some e‑liquid in the pod or tank to ensure the coil is saturated.
  • If using replaceable coils, push/screw them in firmly but don't over tighten.
  • For adjustable power devices, use recommended power settings for the coil or pod you are using (see box, coil or manual).
  • When device is switched on, only press fire button when inhaling. This prevents condensation build up in the pod or tank.
  • If using a refillable kit, use the correct e-liquid for the coil or pod you are using. See the product description for each kit for recommended e-liquid types
  • Avoid filling refillable pods or tanks above the fill line or to the very top.

  • Leave charging batteries unattended.
  • Allow contact between your batteries and water.
  • Carry batteries in a pocket/bag with coins or keys.
