Cartridge resistance affects vapor temperature, draw, liquid consumption and battery life. There is no universally best option — the right choice depends on how you vape.
0.6 Ω — more vapor and a warmer draw. It suits users who prefer a richer taste and a more open draw, but it usually consumes more liquid and battery power.
0.8 Ω — the balanced choice. It offers a comfortable amount of vapor, clear flavor and moderate consumption. For most users this is the easiest starting point.
1.0 Ω — a tighter and calmer draw. It is more economical with liquid and battery, and works well for measured everyday vaping.
If you are unsure, start with 0.8 Ω. Always check that the cartridge is compatible with your device and follow the manufacturer’s recommended power range.
