It comes with a cable with a 12V outlet to the cigar lighter socket or in the trunk. The cable is long enough to put the charger in the front seat or the rear seats but I've tested it in a camper where recharge devices is the cross and the banner because electricity is not easily accessible. Well, I could load without problems two smartphones.
The charger lights using a small button and a small blue light indicates when it is operating, be careful to press the button otherwise your devices will not be charged.
This is a handy little box that will complement my one USB outlet on flow was a bit feeble, to charge my phone in the car, and of course that will be of great use to me camper!
This charger is not however comes with USB-cable> USB microphone so remember to have charging car otherwise you will not be able to charge your devices.
