SMOK RPM Pods Explained: RPM vs RPM 2 vs RPM 3
The SMOK RPM pod series has become one of the most versatile and popular pod systems on the market. With three generations—RPM, RPM 2, and RPM 3—it can be confusing to figure out which pods and coils fit which devices. This guide breaks it down clearly, with practical tips for daily use and replacement so you get the most out of your vape.
Overview of the RPM Series
SMOK’s RPM series was designed to expand beyond the original Nord coils, offering higher wattage, better flavor, and more coil options. Each generation of RPM pods has unique features and vaping performance:
- RPM (Original): Mid-power devices like the RPM40, suitable for MTL (mouth-to-lung), RDL (restricted direct-lung), and DL (direct-lung) vaping.
- RPM 2: Higher wattage, smoother airflow, and optimized for dense vapor. Compatible with devices like Nord X, Nord 4, and Nord C.
- RPM 3: High-power direct-lung pods designed for intense flavor and large vapor production. Works with Nord 5, Nord 6, and RPM 5 kits.
Key Differences Between RPM Generations
Coil Compatibility:
- RPM → Original RPM coils only
- RPM 2 → RPM 2 coils only
- RPM 3 → RPM 3 coils only
Device Fit:
- RPM → Nord 2 RPM Pod, RPM40, and mid-power devices
- RPM 2 → Nord X, Nord 4, Nord C
- RPM 3 → Nord 5, Nord 6, RPM 5
Vaping Style:
- RPM → MTL, RDL, or DL depending on coil
- RPM 2 → MTL or DL, smoother airflow, higher wattage
- RPM 3 → Direct-lung only, large clouds and flavor
Wattage Range:
- RPM → 25–50W
- RPM 2 → 25–50W+ depending on coil
- RPM 3 → 40–80W
Pod Design:
- RPM → Standard press-fit pods
- RPM 2 → Press-fit, higher VG support
- RPM 3 → Press-fit, high-power optimized
Original RPM Pods & Coils (RPM)
- Focus: Built for flexibility, covering MTL (mouth-to-lung) through restricted DTL (direct-to-lung).
- Coil Range: Extensive selection, from 0.3–0.4Ω mesh coils for strong flavor and vapor, 0.6–0.8Ω options for smoother MTL, and 1.0Ω+ coils for higher-resistance vaping.
- Device Support: Compatible with many earlier SMOK favorites such as the Nord 2, Nord 4, and RPM40/80.
RPM 2 Pods & Coils (RPM 2)
- Focus: Designed for higher output and upgraded flavor compared to the original RPM line.
- Coil Options: Commonly available in 0.16Ω mesh and 0.6Ω variants.
- Vaping Style: Best suited for DTL and restricted DTL at higher wattages.
- Device Support: Made for RPM 2 and RPM 2S, and works with several SMOK dual-pod systems.
RPM 3 Pods & Coils (RPM 3)
- Focus: Focuses on maximum flavor, rapid heat-up, and strong DTL performance, especially with high-VG e-liquids.
- Coil Options: Low-resistance 0.15Ω and 0.23Ω mesh coils built for high wattage and thick clouds.
- Device Support: Intended for newer models like the RPM 5, RPM 85, and G-Priv pod kits.
Key Differences & Compatibility Notes
- Coil Design: Each RPM series uses unique coils—RPM, RPM 2, and RPM 3 coils are not cross-compatible.
- Performance Levels: Original RPM excels at low-power and MTL use, RPM 2 offers a middle ground with moderate DTL, while RPM 3 is tailored for high-wattage DTL vaping.
- Refilling Method: Most RPM pods use a side-fill system with a silicone plug to minimize leaks.
- Coil Priming: All RPM coils should be saturated with e-liquid and allowed to sit for at least 15 minutes before use to avoid burning.
Because many SMOK devices (such as the Nord X or Fetch Pro) include multiple pod types, it’s important to confirm which pod and coil series your device supports before choosing replacements.
Daily Use Tips
Maximizing your RPM pod experience isn’t just about picking the right coil—it’s about how you use it every day:
- Prime New Coils: Always soak the coil with e-liquid for 5–10 minutes before first use to avoid dry hits.
- Top Off Before Empty: Refill your pod before it’s fully empty to prevent burning the coil.
- Use the Right Wattage: Follow the coil’s recommended wattage range to extend coil life and maintain flavor.
- Adjust Airflow for Comfort: RPM 2 and RPM 3 pods allow airflow adjustments—tweak it for MTL or DL preference.
- Keep It Clean: Wipe the pod contacts and mouthpiece regularly to maintain performance.
Replacement Tips
Even with careful daily use, coils and pods eventually need replacing. Here’s how to make the process smooth:
- Coil Replacement Frequency: Generally every 1–2 weeks for MTL, 1 week for DL, depending on juice type. High-sugar or high-nicotine liquids may shorten coil life.
- Pod Replacement: Replace your pod if you notice leakage, burnt taste, or persistent low vapor despite a new coil.
- Use Correct Coils: RPM, RPM 2, and RPM 3 coils are not interchangeable. Installing the wrong coil can damage the pod or device.
- Avoid Overfilling: Overfilling can cause leaks; fill just to the max line indicated on the pod.
- Store Pods Properly: If storing unused pods, keep them upright and away from direct sunlight.
Common Mistakes to Avoid
- Using the wrong coil series for your pod
- Overpowering low-resistance coils
- Using the wrong pod type for your device
- Letting your pod run dry before refilling
- Neglecting cleaning, leading to clogs and flavor loss
FAQ: SMOK RPM Pods
Q: Can I use RPM 2 coils in an original RPM pod?
A: No. RPM 2 coils are only compatible with RPM 2 pods.
Q: Which RPM series is best for MTL vaping?
A: The original RPM series is most versatile for MTL. RPM 2 can be used for MTL with higher resistance coils, while RPM 3 is primarily DL.
Q: How do I know which coil to choose?
A: Lower resistance coils (0.16–0.6Ω) are ideal for DL/high-VG juices. Higher resistance coils (0.8–1.2Ω) are better for MTL/nicotine salts.
Q: Why does my RPM coil burn quickly?
A: Common causes:
- Not priming the coil properly
- Chain vaping
- Using too high wattage for the coil type
Always start at the lower end of the recommended wattage range.
