12 Volt Accessories

12 Volt Accessories

Our 12 volt accessories are perfect for use in just about any vehicle or 12V off-grid home. Use one of our socket multipliers to increase the number of accessory outlets in your car, truck or RV. Create a 5v USB power outlet using a 12V to USB adapter. We also carry 12 volt extension cords that handle up to 15amps!

See our tips for using 12 volt accessories safely

[div]

**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.
