Common questions
The honest answers, no fluff.
Need something product-specific? Contact us — same-day reply during business hours.
Does it come with a coil?
Every kit ships with at least one starter coil pre-installed plus one spare in the box. Replacement coils are sold separately under the Accessories category.
Which e-liquid works best in this device?
Pod kits run best on salt nicotine (10–20 mg/mL). Sub-ohm tanks want freebase at 0–6 mg/mL. The nicotine strength guide explains how to pick.
Is the battery replaceable?
Most modern pod kits use a sealed internal battery. Tank mods generally take 18650 or 21700 cells, sold separately — never use damaged or unwrapped batteries.
How do I prime a new coil?
Drip three to five drops of e-liquid onto the cotton through the coil's wicking holes, fill the tank, then wait five minutes before the first pull. Skipping the wait is the #1 reason coils burn early.
Are replacement parts available?
Coils, pods, and glass are stocked under Accessories. The compatibility list on this page links directly to confirmed-fitting parts.
