FAQs

Are the pods cross‑compatible across G4 Pro and G4 Pro KoKo?

Yes — both use the same GPP series pods (supplied 0.4Ω & 0.6Ω).

What e‑liquid should I use?

For 0.6Ω pods, use 50/50 nic salts or freebase for classic MTL. For 0.4Ω, a slightly thicker 60/40 or 70/30 gives a warmer vape.

How do I prevent dry hits?

Prime the pod for 5 minutes after filling, keep the pod above the minimum line, and reduce wattage or airflow if wicking can't keep up.

How long does each battery last?

The G4 Pro (1800mAh) typically lasts a full day of moderate use; the G4 Pro KoKo (2000mAh) adds extra headroom for heavier users or higher wattage vaping.
