Flex DC Control Box, 12/24V Power Distribution Box

Short Product Summary

The Flex DC Control Box is a plug-and-play 12/24V distribution box for your auxiliary battery. Its Anderson, USB, USB-C, cigarette-socket and barrel outlets let you run or charge up to 13 things at once, and the slide-on bracket in the box makes it simple to mount in a 4x4 or camper trailer.

Why This Product

Once a 4x4 or camper trailer has an auxiliary battery, the next job is getting power out of it neatly. A fridge, phones, a DC-DC charger and more all need a connection. A distribution box gives each one its own port and puts the battery status on a display, in place of a tangle of loose leads. Because the box slides off its bracket, it can travel with the battery when the battery leaves the vehicle.

Key Features

• Up to 13 appliances – run or charge plenty of gear from one auxiliary battery
• Four 50A Anderson-style outlets – one connects to the battery and three can work as outputs or charging inputs
• Charge the battery through it – connect a DC-DC charger or a solar panel with regulator to an Anderson port
• Wide port mix – USB-A, QC3.0 USB, USB-C, cigarette sockets and DC barrel ports for phones and other devices
• Fire-resistant ABS body – UL 94V-0 compliant plastic, with ports recessed to reduce damage from knocks
• Built-in voltmeter – a large digital display shows the battery status
• Slide-on mounting bracket – included, so the box can come off and go with the battery

Ideal For

• 4x4 owners with an auxiliary battery who want tidy power distribution in the vehicle.
• Camper trailer owners who want one central point to power fridges and charge devices.
• Overlanders with lots of gear running phones, tablets and a fridge from the same battery.
• Anyone with a DC-DC charger or solar setup who needs an easy charging input to the battery.
