Eleaf iJust 21700 E-cig Kit

Availability: In stock


The Eleaf iJust 21700 is the first iJust kit with a removable battery. It also features new HW fitting coils which produce the biggest volume and density of vapour so far seen in an Eleaf product. The iJust 21700s’ finish and styling is eye-catching and in keeping with other recent and popular iJust models: A simple but highly effective cloud producer with battery capacity to match.


Who is it for?

“Cloud chasers” and those looking for relatively high power – certainly not for the average new user.


Why should they buy?

Vibrant colours and high quality finish make the iJust 21700 a great looking product. The new and innovative HW-M2 and HW-N2 atomizer heads have been designed to couple great flavour with exceptional leak resistance, and provide the ultimate choice for vapers who want larger clouds of vapour. The sliding refill mechanism means the ELLO Duro tank is easy to keep topped up, and with a removable battery, the massive 4000mAh 21700 can be swapped for a freshly charged one quickly and easily.

Product Features

Removable Battery

Removable Battery

The iJust 21700 has classic iJust styling, but can utilise a removable 21700 or 18650 battery. It can output up to 80W of power and has integrated safety features such as short circuit and reverse polarity protection, to keep you vaping safe.

Leak Resistant Atomizer Heads

Leak Resistant Coils

The new style HW-N2 and HW-M2 coils incorporate a new airflow system. Through the centre of the coil is a cylinder which evenly directs air to the coil and cotton, which also reduces the possibility of leaking.

ELLO Duro Tank

With a sliding top fill, bottom airflow and HW coils, the ELLO Duro tank is the ideal match for the iJust 21700.
