Gemz
Gemz RTAs for dialled-in vape setups
At Dampfi, Gemz is available in our rebuildable tank atomizer (RTA) range. These tank atomizers are made for vapers who’d rather set up their own coil, cotton, airflow and power than rely on stock coil heads.
What an RTA does
An RTA combines a refillable tank with a build deck. You build the coil yourself, choose the resistance through your wire and number of wraps, and fine-tune the cotton to control how reliably e-liquid feeds the coil.
Who these atomizers are for
RTAs are a solid choice if you can judge resistance values, understand battery safety and set your mod’s wattage with intent. In return, you get more flexibility than with stock-coil tanks, but you’ll need to build and wick cleanly.
What to watch for when setting up
Flavour, vapour production and draw resistance all come from how the coil, cotton, e-liquid flow and airflow work together. Cotton that’s packed too tightly can choke the wicking, while cotton that’s too loose can encourage leaking; your wattage should match the coil, too.
- Product focus: RTA tank atomizers for self-built coils.
- Best suited to: experienced vapers who want to control resistance, airflow and wicking themselves.
- Essential accessories: coil wire, cotton, tools and a mod that suits your preferred power range.
For a well-balanced setup, treat the atomizer, wire, cotton and e-liquid as one system. That way, you can reduce common issues like dry hits, spitback or excessive e-liquid flow.
