Like it says on the lid, "Power Socket 12V 120W". It looks like an after-market Accessory Socket, similar to the one in the dashboard. As it is mounted in plastic, don't use it for a hot cigarette lighter! Phones and other low current 12V Accessories should be ok.
My Aveo/Barina didn't have an eBrake either, your car must have some custom fittings.
