12V Multi Function Power Extension Box efficiently distributes up to 50Amp power from an auxiliary source to multiple devices, ideal for powering gadgets like phones, tablets, and 12V fridges.

This powerful device can manage 50Amp of electricity, so you can be sure that all of your gadgets including phones, tablets, stoves, and 12-volt refrigerators get the power they require at the same time.

There are several charging options available on the box:

2 x Anderson Style 50A Input/Outputs for high-power needs.
3 x 18 Watt USB Ports and 3 x 18 Watt QC3.0 ports for fast charging of smaller devices.
4 x 30 Amp Fused Accessory Sockets, each with a spare 30A fuse, providing multiple connections for different devices.

It has an auto-reset breaker that guards against overloads and short circuits, safeguarding both your battery and the Power Box. You can power your gadgets without worrying due to this.

With the integrated LED voltmeter, you can always be aware of the condition of your battery. You'll never be caught off guard with this multicoloured, easy-to-read gauge that tells you exactly what voltage your battery is at.

A 3-stage LED light is another feature of the Power Box that guarantees you'll never be left in the dark. This LED light is quite helpful, whether you're camping or handling a roadside issue at night.

This device has both power and versatility. It may be mounted in your caravan, 4WD canopy, or camper. It can also be used as a portable, freestanding gadget. Installation is made simple by the hidden mounting holes and movable source power wire.

Its dimensions are L: 240 x W: 110 x H: 60 mm, making it suitable for a variety of places as well as simple to move and store.

The Power Box is not waterproof and is not a power source in and of itself. Its purpose is to disperse energy from an external power source or battery.
