18V to 12V Power Supplies

The 18V to 12V Step Down Power Supply converts a standard 18–20V tool battery into adjustable 5–13V power at up to 10A through an Anderson plug, with a display showing the output voltage. Pick your battery brand above, or use the Battery platform filter, to see only the versions that fit.

This or the PRO?

• 18V to 12V Step Down Power Supply: adjustable 5–13V at up to 10A through an Anderson plug, with a display showing the output voltage. Suits lights, pumps, fans and single loads around the awning and the tent.
• Volt Step Down PRO: 15A through an Anderson plug, plus a 12V socket and 65W USB-C. Suits a 12V fridge, or running several things at once.

What you can run

• LED lights and light strips
• A water pump, or a Sirocco II fan with an Anderson to 12V socket lead
• A 12V fridge (see runtime below)

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.

Works with

• Plug 12V socket gear into the Anderson outlet with a lead from 12V, USB-C & Anderson Leads.
• Recharge on the drive with an In-Vehicle Battery Charger.
