PETROLHEADS have gone into overdrive after stumbling across a gadget that defogs windscreens in seconds.

The Showvigor portable car heater plugs into a cigarette lighter and blasts hot and cold air out its 12V fan.

Made of heat resistant plastic, the machine will sit on your dashboard to de-mist and de-ice your windshield from the inside.

And at just £16.79 motorists say the device – which can swivel 180 degrees – is “beyond” their imagination.

One said: “Really pleased with it came really fast and does the job brilliantly as my car fan is playing up. Clears windscreen quickly.”

Another chimed: “This car mounted fan is really nice, with cool air that’s perfect for summer.”

And a third said: “This fan is really beyond my imagination and is very easy to use.”

The machine promises to end the days of scraping ice off your windscreen and stop your fingers freezing over.

It will also blow cool air at you when the weather heats up.

What’s more, the base can be covered with double-sided adhesive allowing you to fix it to your preferred position.

The three-outlet fan is compatible in everything from a micro car to campervans and supercars.

Makers Shogiver say the fan – which measures 6.3 inches by 5 inches – will also keep you toasty while out camping.
