An electric vehicle charger 10 includes a reel or drum 18 for coiling a cable 14 inside a casing 12 when the cable 14 is not in use, the casing defines a void around the drum, and apertures in the casing 26 and 28 together with a fan 32 draw air from outside, through the void, and back out of the charger, the fan thus reduces the temperature at the cables. A baffle 30 may be used to direct air around the extent of the drum. A controller may be included which controls the fan dependent on the state of the charger, i.e. whether it is in use, how long it has been since it was used or its temperature. Slip ring electrical connections may be included inside the drum.
