12 Volt Accessories

These 12 volt accessories are perfect for use in just about any vehicle or 12 volt off-grid home. If you're looking to increase your number of 12 volt accessory outlets or come out of one with 5v USB power you're in the right spot. We also carry 12 volt extension cords that handle up to 15amps!

These 12 volt accessories are for use with other 12 volt products. 12 Volt Accessories simply make it easier and safer to use your 12 volt appliances or other 12 volt items.

12 Volt Accessories

  • Accessories for Car
  • Accessories for Truck
  • Accessories for Motorhome
  • Accessories for Camper
  • Accessories for RV


**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.
