Eleaf iJust S-Max-Quality image

The iJust S model is a new product launched by Eleaf aimed at beginner users. This device has replaced the iJust 2, which was in great demand a few years ago.

The iJust S embodies all the advantages of the previous model, and the manufacturer has also introduced a number of innovations. This is manifested primarily in an increase in the capacity of the built-in battery, which is 3000 mAh.

The small tank has also been redesigned, in this case, we are talking about the introduction of top filling, another innovation is the ability to install new glass.

The standard package includes the iJust S mod and the tank, it has an identical name. In terms of the kit, there is a lot in common with iJust 2 – the standard image was saved at the initiative of the manufacturer.

Among the features of the model, one can single out low resistance and high power ratings, thanks to which iJust S has the ability to produce a large amount of vapor.

The mod board, without user participation, selects the power, focusing on the coil that was installed. Also, the power indicators are affected by the battery charge level, with a high charge level, the device produces more power. You cannot change the power yourself.

Another feature is the possibility of a device for pulling various windings with a resistance of 0.15 – 0.2 Ohm. For this reason, power ratings may exceed those declared by the manufacturer.

The model under consideration supports the resistance in the range of 0.15 – 3.5 ohms. If you use a coil with a lower resistance, the protection system will be activated and the device will not turn on.

The iJust S battery has a large capacity and high power ratings, which makes it suitable for use with sub-ohm tanks and RDAs.

The standard diameter is 24.5 mm, for this reason, there are a number of restrictions when choosing tanks and drip tips – it is better not to use models with a diameter of 22 and 23 mm.

Alternatively, devices with a diameter of 24 or 25 mm can be considered, while there will be a “rim” visible when looking closely. For example, the GeekVape Avocado, Tsunami, and Goon RDAs are well suited for the mod, as well as the Griffin 25, OBS Crius Plus, and Tornado Nano tanks.

It is important to note that most RDAs come in black color options.

For operation with iJust S, the best option is steel wires, resistant to corrosion. Their response and heating do not take much time, which was made possible due to the properties of the metal.

Another option worthy of attention is sub-ohm wires, they can also be used with this model with good portability.

The standard package includes a built-in battery with a capacity of 3000 mAh, which is much better than the previous model. The battery is charged by using the USB connector located on the side of the device.

The process of replenishing the charge to 100% takes an average of 4 hours. The pastru function is reflected in the instructions that came with the device, which determines access to the use of the mod without interrupting charging.

The minimum battery voltage is 3.3 V. If this indicator is reached, the protection system is activated, eliminating the possibility of overcharging. You can turn on the device only after charging reaches 3.7 V. Under the “Fire” button there is an LED that displays the current charge level:

  • From 100 to 60% – the LED does not blink;
  • From 59 to 30% – the LED starts blinking slowly;
  • From 29 to 10% – the LED flashes quickly;
  • From 9 to 0% – the LED flashes very quickly.


510 connector made of steel, complemented by a spring-loaded brass pin.

The kit includes iJust S tank, its capacity is 4 ml. A distinctive feature of this tank compared to the previous model is the top filling – you need to unscrew the top cover and fill the tank.
