SKYsmoke PRO-G MOD houses the brain and the battery of the SKYsmoke PRO G MOD System. The product uses an innovative operating system that saves, monitors and manages your smoking history. PRO-G is a part of the MOD (modifications) product groups and its 2200 mAh or 3400 mAh lithium-ion battery (purchased separately) enables e-cigarettes to be used nearly 5 times longer than the more popular eGo products. Equipped with a new generation, 510/eGo threaded glassomizer (purchased separately), the Pro-G is a ground-breaking product that introduces us to a new trend in electronic cigarette production. NB! In order to use the product, an e-liquid, glassomizer, battery, USB cables and an adapter must be purchased, i.e. this is an add-on/replacement product! The product is aimed at advanced users or demanding vapers!
