To ensure a seamless vaping experience for your customers, it's essential to verify the compatibility between the e-liquids and the specific vaping devices you offer. Factors such as coil resistance, PG/VG ratio, and nicotine strength need to be considered. Consulting the device manufacturer's specifications and guidelines, as well as liaising with e-liquid suppliers, can help you make informed decisions about which e-liquids are compatible with the vaping devices in your inventory.
