The SMOK RPM40 was one of the first true pod mod devices to blend compact design with adjustable power and airflow. If you’re looking to keep yours performing at its best, choosing the right RPM40 pod and coil combination makes all the difference.
In this guide, we’ll break down:
- The difference between RPM40 pod versions
- Which coils are compatible
- MTL vs DTL options
- Which coil suits your vaping style
- Important compatibility notes
SMOK RPM40 Replacement Pods Explained
The SMOK RPM40 replacement pods are designed exclusively for the RPM40 device.
Features:
- 2ml e-liquid capacity (TPD compliant)
- Wide mouthpiece for increased vapour production
- Adjustable airflow
- Magnetic pod connection
- Side-fill silicone plug for quick refills
You can quickly check your remaining e-liquid by removing the magnetic pod and inspecting the chamber.
Two Pod Versions Available
There are two RPM40 pod types:
- RPM Coil Compatible Pod (Red silicone plug)
- Nord Coil Compatible Pod (Black silicone plug)
This allows you to choose between the full RPM coil range or Nord coil compatibility, depending on your vaping preference.
Important: RPM40 replacement pods are not compatible with other devices and are specifically designed for the RPM40.

Which Coil Should You Choose?
For tight MTL vaping with nicotine salts:
Choose the 1.0Ω SC or 1.2Ω Quartz coils with a 50/50 or high-PG e-liquid.
For slightly airier MTL with balanced vapour:
Choose the 0.8Ω DC or 0.3Ω Mesh coils with 50/50 e-liquid.
For restricted direct-lung vaping and bigger vapour production:
Choose the 0.4Ω Mesh or 0.6Ω Triple coils with 60%–70% VG e-liquid and lower nicotine strengths.
Using the correct VG/PG ratio improves flavour, reduces leaking, prevents dry hits, and extends coil lifespan.
Frequently Asked Questions (FAQs)
1. How long do SMOK RPM40 coils last?
On average, RPM coils last 1–2 weeks, depending on wattage, e-liquid type, usage frequency, and whether the coil was properly primed. Sweeter e-liquids may reduce coil lifespan.
2. Can I use RPM coils in other SMOK devices?
RPM coils are compatible with SMOK devices that use RPM pods (where “RPM” is printed on the e-liquid flap). Always check your device compatibility before purchasing.
3. What’s the difference between the red and black RPM40 pods?
Red plug= RPM coil compatible
Black plug= Nord coil compatible
The colour of the silicone plug indicates which coil series fits the pod.
4. Can I use 70VG e-liquid in the RPM40?
Yes — but only with lower resistance coils such as the 0.4Ω Mesh or 0.6Ω Triple. Higher resistance coils like the 1.0Ω and 1.2Ω perform best with 50/50 e-liquids.
5. Why does my RPM40 coil taste burnt?
Common causes include:
Not priming the coil before first use
Vaping above recommended wattage
Letting the pod run too low on e-liquid
Using high-VG liquid in high-resistance coils
Always let a new coil soak for 5–10 minutes after filling before vaping.
6. Is the RPM40 good for beginners?
Yes. The RPM40 is beginner-friendly thanks to adjustable wattage, simple coil replacement, clear e-liquid visibility, and a wide range of compatible coils. It suits both new vapers and experienced users.
Final Thoughts
The SMOK RPM40 pod and coil system remains one of the most versatile pod mod platforms available. With both RPM and Nord compatibility, plus multiple coil resistances, you can tailor your vape to suit your exact preference.
Whether you prefer a smooth, cigarette-style MTL draw or a more vapour-focused RDL setup, the RPM40 delivers consistent flavour, reliable performance, and everyday convenience.
