Up and running in seconds

How it works

Clip in a battery - slide on your 18V tool battery.

Press power - the Booster is ready in a second.

Plug in & go - 240V socket, USB, USB-C and LED work light.

Built-in protection

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.

Overheat protection

Throttles or shuts down before heat can damage the unit or your battery.

Overload protection

Trips if you exceed 180W - protects the inverter and whatever's plugged in.

Overcharge protection

Stops your tool battery being drained or stressed beyond a safe level.

Short-circuit protection

Instantly shuts down on a wiring fault - no sparks, safe to reconnect.

Is it safe for my electronics?

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.

Where it shines

Perfect for

Camping & off-grid

Run small appliances, charge devices and light up camp using the batteries you already own.

4WD touring

Compact backup power for remote trips - no heavy battery boxes or generators.

Tradies on site

Charge tools, phones and tablets and run small devices wherever work takes you.

Emergency backup

Blackouts, roadside breakdowns and storm prep - power when you need it most.

Seen the cheap inverters?

Why this one's different

No bulky separate power station - just clip on the 18V tool battery you already have.

Try it risk-free

30-day returns, no fuss. If it doesn't suit your setup, send it back.

Good to know

Questions, answered

Which battery should I pick?

Choose the brand of the 18V batteries you already own - the Booster mounts straight onto them. Each unit is brand-specific, so it isn't cross-compatible. If your brand isn't listed, get in touch and we'll help.

What can The Volt Booster power?

Phones, laptops, lights, cameras, drones, fans, chargers and small low-wattage appliances - anything under 180W. Try the runtime calculator above for your exact device.

Can it run my camping gear?

Yes. It's perfect for charging portable devices, powering lights and running small camp essentials off the tool batteries you already carry.

Is it safe for sensitive electronics?

Yes. The Booster puts out a pure sine wave - clean, mains-quality power - plus built-in protection, so it's safe for laptops, CPAP machines, cameras and other sensitive gear.

Does it include a battery?

No - your tool battery is sold separately. That's the whole idea: the Booster runs off the 18V batteries you already own, so there's no expensive separate power station to buy.

Why buy this instead of a power station?

If you already own 18V batteries, the Booster gives you portable 240V power without the cost, bulk and weight of another battery system - just clip on a pack and go.
