iJust 21700 Starter Kit | Featuring Ello Duro 5.5ml Tank



Eleaf iJust 21700 with Ello Duro Tank

The Eleaf iJust 21700 is the “next generation” sibling of the wildly popular iJust 3. What makes this kit a useful upgrade from the iJust 3 is it’s user-replaceable battery feature!  You can install a high capacity 21700 battery, or use a standard 18650 high-drain battery with the included adapter.  Rock Bottom Vapes offers this kit both with and without a 4000 mAh – 21700 battery direct from the factory.  So, if you already have a 21700 cell or want to use your existing 18650 cells you can save a few bucks and order the kit without a battery.

Like its sibling, this simple to use tube style device can support up to 80W of output.  This device is not just any run of the mill tube-style mod though, as it boasts a beautiful laser-etched design in five vibrant finishes.  Included with the iJust 21700 is the equally gorgeous and powerful ELLO Duro tank. The Duro tank which ships with this kit has a gorgeous color-matched acrylic tank.  This tank uses the latest Mesh (HW-N2) and Multihole (HW-M2) coil systems which provide more uniform heating of the wick.  What does this mean for you?  In a word – FLAVOR. The ELLO Duro has a 5.5mL maximum e-liquid capacity (depending on the tube installed), and features a retractable top-fill design and rotatable dual bottom airflow ports.
