1. The Powerhouse: iStick XC100 Mod
At the core of this kit is the impressively designed XC100 mod, which is packed with features that cater to both beginners and seasoned enthusiasts.
-
Single 21700 / 18650 external battery: This is the kit’s headline feature. It provides enough power to last a full day, or even multiple days, for moderate vapers, supporting up to 100W of output.
-
Full-Featured E-Cigarette Chipset: The advanced chipset ensures a responsive, consistent, and safe vaping experience. It offers a full suite of output modes:
-
SMART Mode: Automatically recommends the optimal wattage for your installed coil.
-
Variable Wattage (VW) Mode: For manual power control from 1W to 100W.
-
Bypass Mode: Delivers a direct output voltage for a mechanical mod-like experience.
-
-
Rapid USB-C Charging: While the battery is large, you won’t be waiting forever to recharge. The USB-C port supports fast charging, getting you back to vaping in no time.
-
Intuitive 1.05-inch TFT Screen: A bright, colorful display provides all crucial information at a glance, including wattage, resistance, battery level, puff counter, and mode setting.
-
Sturdy and Ergonomic Construction: The zinc-alloy frame provides durability, while its rounded edges and comfortable grip make it a pleasure to hold and use.

2. The Flavor Machine: Melo X Sub-Ohm Tank
Paired perfectly with the powerful mod is the Melo X Tank, a top-fill sub-ohm atomizer known for its excellent flavor production and sleek design.
-
Top-Fill Design: Refilling is a breeze. Simply slide open the top cap to reveal two large fill ports, allowing you to add e-liquid quickly and cleanly without removing the tank.
-
Versatile Coil Compatibility: The Melo X is compatible with the extensive range of Eleaf EC and P Series coils, giving you immense flexibility to tailor your vape. Popular options include:
-
EC-M 0.15Ω Coil (60-75W): Ideal for direct-to-lung (DTL) vaping, producing massive clouds and intense flavor.
-
EC 0.3Ω Coil (30-60W): A great balance of warm vapor and rich flavor at a moderate wattage, helping to conserve battery life.
-
-
Adjustable Bottom Airflow: The precisely controlled airflow ring allows you to fine-tune your draw from a tight, restricted lung hit to an ultra-airy, wide-open experience.
-
5mL E-Liquid Capacity: The generous glass tube minimizes the frequency of refills, making it ideal for pairing with the long-lasting XC100 mod.
Who Is The Eleaf iStick XC100 Kit For?
-
Intermediate to Advanced Vapers: Users looking to upgrade from a beginner pod system or a lower-wattage mod will appreciate the power and customization.
-
Cloud Chasers & Flavor Enthusiasts: The combination of 100W power and the Melo X tank delivers dense vapor and exceptional flavor.
-
Vapers on the Go: The Single 21700 / 18650 external battery is a godsend for commuters, travelers, and anyone who doesn’t want to worry about carrying extra batteries.

Those Who Value Simplicity: The internal battery means no fussing with external chargers or battery safety rules, offering a “plug-and-play” high-wattage experience.
