A recent trend in the industry is converting existing Stlth Loop Batteries and Level X Batteries to a refillable system system where you can save some money by purchasing a salt nic bottle and refilling yourself. This is a cost saving option with a bit of extra work.
Level X Refillable System
With any Level X battery:
purchase the Refillable Dual Coil Pod and you have an instant refillable device available here Level X Refillable Pods. We carry Flavour Beast Salt Nic 30ml Bottles here (Salt Nic Collection). Save even more with the SOS (Save On Salts) 60ml bottles available here.
STLTH LOOP REFILLABLE SYSTEM
Available here the Stlth Loop Refillable Pod works with your Stlth Loop Battery. It holds 3ml of e-liquid and designed for use with any salt nic brand but manufactured with STLTH Salt Nic in mind.
Here is complete list of compatibility between Level X Pods (Beast G2, Beast Ultra, Level X Refillable, Ripper X, Loop 9k, 25k, Switch and Loop Max).
Whatever your style of vaping, these are two interesting options for your consideration.
