**Important** When using socket multipliers to increase the number of 12 volt accessory outlets be careful not to overload. You must make sure that the fuse and wiring used in the vehicle to supply power to the original socket can handle everything you intend to plug in.

For example: The fuse is 10A and the wires leading to the socket are 16 gauge.
You intend to plug in a socket multiplier that offers three sockets and one item into each new socket. Unless all three items total draw is less than 10 amps you will "blow" the fuse.
