Volt Step Down PRO

The Volt Step Down PRO is the one to choose if you want to run a 12V fridge away from the vehicle, or several things at once. It earns its place when the car is parked up for a few days: the fridge in the shade, a fan in the rooftop tent overnight, the lights under the awning, all without drawing on the auxiliary battery. Pick your battery brand above, or use the Battery platform filter, to see only the versions that fit.

Outputs

• Anderson (SB50) plug, up to 15A, for a 12V fridge or other high-draw gear
• 12V socket for lights, a pump or a Sirocco II fan
• USB-C PD up to 65W for laptops, phones and a Starlink Mini

How long will it run a fridge?

At temperature, most 12V fridges average about 1 amp, so a 12Ah tool battery gives roughly 12 hours. Pre-cool the fridge on the drive in; hot days make it cycle more and shorten that. Swap in a second battery to keep going.
