Smok RPM 3 Replacement Coils – High-Wattage Mesh
SMOK RPM 3 coils are designed for more powerful devices and higher wattage output, using advanced mesh technology for improved flavour and vapour production.
RPM 3 Coil Option
0.15Ω Meshed Coil
- 0.23Ω Meshed Coil
Compatible Devices
SMOK RPM 5
SMOK RPM 5 Pro

RPM 3 coils are not compatible with RPM or RPM 2 devices.
0.15Ω RPM 3 Mesh
Best Range:40–80W
Ideal for DTL vaping
Produces warm, dense vapour
Best paired with 0–10mg nicotine
Designed for high-performance devices
This coil is perfect if you enjoy big clouds and a warmer vape.
0.23Ω RPM 3 Mesh
Best Range:20–45W
Suitable for restricted DTL or loose MTL
Works with 0–20mg nicotine
Power can be reduced (around 20W) to soften throat hit and extend coil life
This option provides more flexibility for users who want strong flavour without extremely high wattage.
Which RPM Coil Should You Choose?
Choose RPM (Original) if:
- You want the widest variety of resistance options
- You prefer lower wattage vaping
- You like MTL-style draws
Choose RPM 2 if:
- You want more airflow and higher power capability
- You use devices like Nord 4, Scar P5 or IPX80
- You switch between MTL and DTL
Choose RPM 3 if:
- You prefer high wattage (up to 80W)
- You enjoy dense vapour and strong flavour
- You use more advanced, powerful pod mods
Frequently Asked Questions – SMOK RPM, RPM 2 & RPM 3 Coils
- What’s the difference between RPM, RPM 2 and RPM 3 coils?
Smok RPM Replacement Coils (Original RPM)– Wide range of resistance options for both MTL and DTL vaping. Generally lower wattage and highly versatile.
Smok RPM 2 Replacement Coils– Designed for more airflow and slightly higher wattage output, offering stronger vapour production.
Smok RPM 3 Replacement Coils– Built for higher wattage devices (up to 80W), using advanced mesh for dense vapour and bold flavour.
In short: RPM = versatile, RPM 2 = more power, RPM 3 = high-performance mesh.
2. How do I know which RPM coil fits my device?
Check your pod or device:
If it says RPM, use RPM coils.
If it says RPM 2, use RPM 2 coils.
If it says RPM 3, use RPM 3 coils.
Coils are not cross-compatible between different RPM pod types.
3. Which RPM coil is best for MTL (Mouth-to-Lung) vaping?
For a tighter, cigarette-style inhale:
RPM 1.0Ω SC
RPM 1.2Ω Quartz
RPM 2 DC 0.6Ω
RPM 3 0.23Ω (at lower wattage)
Higher resistance coils (above 0.6Ω) generally work best for MTL vaping and higher nicotine strengths.
4. Which RPM coil is best for DTL (Direct-to-Lung) vaping?
For bigger clouds and a looser draw:
RPM 0.4Ω Mesh
RPM 2 0.16Ω Mesh
RPM 2 0.25Ω DC
RPM 3 0.15Ω Mesh
Lower resistance coils (below 0.4Ω) are ideal for DTL vaping and lower nicotine e-liquids.
5. What nicotine strength should I use with each coil?
High wattage / low resistance (0.15Ω–0.3Ω):
Best with 0–6mg nicotine (up to 10mg max).
Mid-range (0.4Ω–0.6Ω):
Works well with 3–12mg.
Higher resistance (0.8Ω–1.2Ω):
Suitable for 10–20mg nicotine salts.
Using high nicotine with very low resistance coils may cause a harsh throat hit.
6. How long do RPM coils last?
On average, RPM coils last 1–2 weeks, depending on:
Wattage used
E-liquid type (sweet liquids shorten lifespan)
Frequency of vaping
If you notice burnt taste, reduced flavour, or gurgling, it’s time to replace the coil.
7. Can I use regular freebase e-liquid with RPM coils?
Yes — but it depends on the coil:
Low resistance coils (DTL)→ Best with high VG freebase e-liquid (70VG).
Higher resistance coils (MTL)→ Better with 50/50 VG/PG or nicotine salts.
Matching the correct e-liquid ratio helps prevent leaking and extends coil life.
8. How do I make my RPM coil last longer
Prime the coil before first use (let it soak for 5–10 minutes).
Stay within recommended wattage ranges.
Avoid chain vaping.
Use appropriate VG/PG ratio for your coil type.
Final Thoughts
The SMOK RPM coil family is built around flexibility. From tight MTL inhales to powerful DTL cloud production, there’s a coil for every style of vaper.
The key is matching:
- Resistance (Ω)
- Wattage range
- Nicotine strength
- Device compatibility
Choosing the correct combination ensures better flavour, longer coil life and a more satisfying vape overall.
