It’s easy. Your portable charger case will charge your multiCIG battery up to eight times before it needs to be charged itself. You charge your portable charger case using the USB or mains adaptor provided with your starter kit.
Remember that unlike many other leading brands, you don’t have to charge your portable charger case before you charge a battery. You can do it at the same time.
Once your portable charger case is charged, screw one of the batteries into the charging slot (the slot on the far right). Press the right hand side of the silver button to activate the display and hold this down until the LED turns red. When the LED is red, your battery is charging. When the LED turns blue, your battery is fully charged. You can then screw your chosen multiCIG cartridge into your battery.
