12V camp power from your Bosch 18V battery

The Volt Step Down PRO clips onto a Bosch Professional (blue) 18V battery and turns it into a portable 12V supply for camp: 15A through an Anderson plug for the fridge, a 12V socket for lights, a pump or a Sirocco II fan, and 65W USB-C for a laptop, phone or Starlink Mini.

It earns its place when the car is parked up for a few days. Run the fridge at camp, keep a fan going in the rooftop tent overnight, or power the lights under the awning without draining the vehicle battery.

Outputs

  • 12V Anderson plug, 15A continuous (about 20A peak for roughly 8 minutes)
  • 12V cigarette socket, 10A
  • USB-C PD3.0, up to 65W
  • USB-A, 5V 2.4A

Fridge runtime

At temperature, a 12V fridge draws about 1 amp on average, so a 12Ah battery gives roughly 12 hours. Pre-cool the fridge first; hot weather shortens runtime.

Before you buy

  • Fits Bosch Professional (blue) 18V slide-on batteries. Battery not included.
  • Low-voltage, over-current and short-circuit protection built in.
  • Don't use dual-battery adaptors, and never combine two batteries at different charge levels. Both can damage the batteries.
  • For lights, fans and smaller loads, the 18V to 12V Power Supply is a lighter-duty option.

Questions

Does it come with a battery?
No. It fits the Bosch Professional (blue) 18V batteries you already own. A bigger battery (higher Ah) runs your gear for longer.

How long will it run a 12V fridge?
At temperature, a 12V fridge draws about 1 amp on average, so a 12Ah battery gives roughly 12 hours, and a 5Ah battery about 5 hours. Pre-cool the fridge first; hot weather shortens runtime.

Can I run more than one thing at once?
Yes. The Anderson plug, 12V socket and both USB ports work together, up to 15A in total (about 20A for short peaks of roughly 8 minutes).

Bosch is a trade mark of its owner. This is an aftermarket product, compatible with Bosch Professional (blue) 18V batteries but not made, approved or endorsed by Bosch.
