The Uwell Caliburn G5 is highly versatile and can use both Nicotine Salts and Freebase E-Liquids.
Because it operates at up to 35W and uses the Uwell GPP / GPP Alpha pod series across multiple resistance levels, the best e-liquid for you depends entirely on which pod/coil resistance you insert:
1. Nicotine Salt E-Liquids (Nic Salts)
- Best Pods: 0.9Ω or 1.2Ω GPP pods
- PG/VG Ratio: 50/50 VG/PG or 60/40 VG/PG
- Nicotine Strength: High nicotine (e.g., 10mg, 20mg)
- Vape Style: Mouth-to-Lung (MTL) — gives a cigarette-like throat hit with a tighter draw and lower wattage output.
2. Freebase Nicotine E-Liquids
- Best Pods: 0.4Ω or 0.6Ω GPP / GPP Alpha pods
- PG/VG Ratio: 60/40 VG/PG or 70/30 VG/PG (70VG runs well in the lower-ohm 0.4Ω/0.6Ω pods)
- Nicotine Strength: Low nicotine (e.g., 3mg, 6mg, or 12mg)
- Vape Style: Restricted Direct-to-Lung (RDL) or loose MTL — generates warmer vapor, larger clouds, and smooth flavor production.
Key Takeaway Summary
| Pod Resistance | Ideal E-Liquid Type | Best VG/PG Blend | Typical Wattage Range |
| 0.4Ω Pod | Freebase Nicotine (3mg – 6mg) | 70/30 VG/PG | ~25W – 35W |
| 0.6Ω Pod (Included) | Freebase or Low Nic Salts (6mg – 20mg) | 50/50 or 60/40 VG/PG | ~15W – 25W |
| 0.9Ω / 1.2Ω Pods | Nicotine Salts (20mg – 50mg) | 50/50 VG/PG | ~10W – 15W |
Tip: Avoid ultra-thick Max-VG e-liquids (e.g., 80VG/20PG or higher), as pod coils struggle to wick thick oil quickly enough, which can burn out your coils prematurely.
