⚠️ Important Safety and Purchase Clarity
This device features a removable 3000mAh rechargeable battery that arrives included in the kit and charges via a Type-C fast-charging cable. You must ensure you use compatible Eleaf GTL-D coils or standard GTL series coils for replacements. This intermediate-level kit is designed for simple operation, but you should always understand proper wattage settings for your specific coil resistance to prevent dry hits.

iStick X40 Kit with GTL X Tank
