How to use the retractable USB cord?
You can extend the USB cord at any length you want. When the cord reaches the maximum length, try to pull it again and then it will retract back automatically.

Note: The center pin in the battery is adjustable. If it can not work with any cartomizer/ atomizer, it may because of the poor contact of them, so you can try to use tweezers to pull up the center pin.This passthrough can be used with our universal and flat mini AC-USB adapters on wall socket or car usb adapter.
