Clears frost and fog from windscreens
Runs off any 12V socket
Switches between heat and cool air

A cold car takes a long time to warm itself, and the windscreen usually clears last. This 12V ceramic heater plugs into the cigarette lighter socket and pushes warm air out immediately, so it can be aimed at the glass to break up frost and fog while the engine is still cold.

Two power levels, 150W for steady warmth and 300W for fast defrosting, cover the difference between clearing a screen quickly and keeping a cab comfortable on a long drive. Ceramic PTC elements are used instead of open coils because they self-regulate: as the element heats it draws less current, which holds the surface temperature stable. The head swivels on its base to direct air at the windscreen, side glass or footwell, and a weighted base with a non-slip pad keeps it upright on a dashboard. It runs as a plain fan in warm weather.

It is useful on frosty mornings, in older cars with slow heaters, and in vans and camper conversions. Treat it as an auxiliary heater rather than a replacement for a working demister. Do not run it for long with the engine off, as it will flatten the battery. Never cover the unit or leave it running unattended, keep it clear of fabric and paperwork, and let it cool before stowing it away.

12V Car Heater and Defroster Fan, Clear Glass Fast

Clear Glass Fast

Aim the vents at the glass and the warm airflow pushes fog and light frost off the inside of the windscreen. You get a clear view without waiting for the engine to come up to temperature.

12V Car Heater and Defroster Fan, Plugs Straight Into 12V

Plugs Straight Into 12V

The cable ends in a standard cigarette lighter plug, so setup is one connection and a switch. There is nothing to wire in and nothing to install permanently.

12V Car Heater and Defroster Fan, Warm Up On Cold Mornings

Warm Up On Cold Mornings

Park it on the dash on a school run or an early shift and take the edge off the cabin while you drive. Plainlys kept it small enough to live in the glovebox all winter.

Frequently Asked Questions

How do I set it up?
Sit it on the dash or console, plug the lead into your 12V socket and flip the switch. There is no installation and no tools involved, so it is ready in under a minute.
Does it also blow cool air?
Yes, a switch moves it between warm air and a plain fan setting. That makes it useful in summer as well as for defrosting in winter.
Which vehicles is it compatible with?
Any vehicle with a standard 12V socket works, including cars, vans, SUVs, campers and most trucks. The compact body fits easily on a dashboard or console.
Will it stay put while driving?
The wide base and non slip feet hold it steady on a dash, and the rotating head lets you aim the airflow without moving the unit. It stays where you set it on normal roads.
How do I keep it working well?
Keep the intake and vents free of dust with a dry cloth or a quick blast of air, and coil the cable when you store it. Clean vents keep the airflow strong season after season.
