The integrated 1100mAh battery uses direct output, meaning there are no settings to adjust. The Eleaf iJust ONE will detect the resistance of your atomizer head and output the correct wattage based on the charge of the battery. The LED light within the battery will also indicate when you need to recharge by flashing at different rates.
The 2ml e-liquid tank can be conveniently refilled through the top of the e-cig, this is great for on the go refills as you do not need to remove your atomizer to top up your e-liquid. The tank will also accommodate two types of atomizer head, the EC or the GS. The EC sleeve will allow the iJust ONE to accommodate a GS atomizer head adding great versatility to this kit.
This small tube mod also packs some protection, with dual circuit protection to help prevent over charging and discharging. The side USB port is ideal for convenient recharging, while the whole tank comes apart for easy cleaning and maintenance.
