How it works
Safe for your gear and your batteries.
The Volt Booster puts out clean pure sine wave power with four-way protection built in - the safeguards the cheap modified-sine inverters skip.
Throttles or shuts down before heat can damage the unit or your battery.
Trips if you exceed 180W - protects the inverter and whatever's plugged in.
Stops your tool battery being drained or stressed beyond a safe level.
Instantly shuts down on a wiring fault - no sparks, safe to reconnect.
Yes. Pure sine wave output is clean, mains-quality power - safe for laptops, CPAP machines, cameras and other sensitive gear, unlike the cheap modified-sine units.
Perfect for
Run small appliances, charge devices and light up camp using the batteries you already own.
Compact backup power for remote trips - no heavy battery boxes or generators.
Charge tools, phones and tablets and run small devices wherever work takes you.
Blackouts, roadside breakdowns and storm prep - power when you need it most.
Why this one's different
Clean, mains-quality 240V - safe for laptops, CPAP, cameras and sensitive electronics.
No bulky separate power station - just clip on the 18V tool battery you already have.
Family-run and independent. Questions answered by people who actually use this gear, and a 2-year warranty honoured wherever you are.
