    Easy to use 8 level variable voltage function

    J-Easy 9 battery is designed as a variable voltage type which is most suited for JUSTFOG coil cylinders.

    The wattage is adjusted automatically as the voltage is increased or decreased, finding the perfect voltage output

    for your device. The voltage can be adjusted easily between 3.4V ~ 4.8V by simply pressing ‘+’ ‘-’ buttons.

    Accurate constant voltage output throughout all voltage ranges

    For many variable voltage battery products, the voltage outputs are often inconsistent depending on the remaining

    battery charges, or if there are sudden decreases of the battery voltages.

    But JUSTFOG J-Easy 9 battery shows consistent voltage outputs regardless of the remaining battery life

    due to the constant voltage circuit.

    This constant voltage function is one of the most important functions for consistent flavor of electronic cigarettes.

    Strong and long lasting grade A powered battery cell

    The battery cell inside of J-Easy 9 battery is a grade A powered cell.

    J-Easy 9 yields accurate voltages even at high voltages (4.8V) and it lasts long due to the high yield value.


    Five intelligent protection circuit functions

    To improve the user safety and battery life durations, J-Easy 9 battery is equipped with 5 types of protection circuits.

    These protection circuits get activated automatically on special conditions, giving its users high safety.

    Short protection

    If a short occurs with the clearomizer and battery connections or for any other reasons,

    all LED lights at the front side of the battery will blink 4 times before the protection circuit automatically

    shuts down the power.

    Overheat protection

    If the battery power button is pressed for more than 10 seconds,

    all LED lights will blink 10 times before the protection circuit automatically turns off the power.

    Over-discharge protection

    Before the battery is over-discharged, the LED light will blink 10 times before the circuit automatically

    shuts off the power, preventing battery malfunction from over-discharge.

    Overcharge protection

    When the battery charging is completed, the charging stops automatically,

    preventing decreased battery cell life resulting from overcharging.

    Over voltage protection

    When the battery is charged by too high voltages,

    the protection circuit automatically shuts down the charging preventing accidents.

    Battery life display in 5 levels

    Remaining battery life can be checked conveniently by the LED display at the front side of the battery.

    During the course of the battery usage, the LED display will be turned off one level at a time as the remaining battery life drops.

    For a longer battery life, completely chage the battery before using the device when using it for the first time.

    Also charge the battery before it is completely discharged.


    Charging: The LED battery bar moves by one gauge at a time until 100% charged. Charging complete: All five LED battery bars are displayed on.

    Easy Power ON/OFF function

    For the time when you are not using the device, turn off the power for a longer battery life. Battery can be turned on and off easily by pressing the power button quickly 5 times in 2 seconds.

    Small, portable and lightly designed battery

    J-Easy 9 battery manages to have a charging capacity of 900mAh and variable voltage function,while keeping the battery length as short as 650mAh batteries. Also the battery is quite light compared to other typical MOD batteries, making it very easy to carry.

    CE and RoHS certified safe electronic cigarette

    The product is certified by, and meets the all standards of European Conformity CE, Restriction of Hazardous Substances RoHS.  Further more, both ends of the battery is made with insulated materials, making the device safer.
