12v Control Box

If you're running a dual battery setup, a 12V control box is the simplest way to manage all your power in one spot. Instead of hunting for individual switches, fuses, and connections scattered across your rig, everything's in one place - backlit switches, USB ports, cig sockets, and power inputs all wired and ready to go.

Our control boxes give you clean, organised access to your auxiliary battery. Flip a switch to run your lights, charge your phone through the USB ports, or plug in your fridge. Built-in fuse blocks protect your gear, and digital voltage displays keep you across your battery's state so you're never caught out with a flat.

We've got options whether you're tight on space or need something with more grunt. Compact units fit into smaller setups like canopies and caravans, while our premium models come with integrated DC-DC chargers, battery monitors with shunts, and multiple power outputs. All our control boxes use quality components that handle Aussie heat, dust, and rough roads without missing a beat.

Installation is straightforward. Most units are plug-and-play or near enough - mount the box, connect your battery, and you're sorted. If you're setting up a full system, pair your control box with our wiring and connectors or add a battery monitor for even more visibility over your power. Looking to expand your setup? Our accessory panels and electrical accessories let you customise further as your needs grow.

No more tangled wires or blown fuses you can't find. Just clean, reliable power control that works.
