Our Picks for Best 12 Volt Portable Car Window Defroster

By | November 1, 2018


Having a portable window heater defroster on colds days can be very handy to have.
There are may units available most of which are 12 volt units that sit on the dashboard.
One thing to keep in mind is that 12 volt systems don’t put out a lot of energy and so can be slow when it comes to defrosting a window.
It really comes down to how cold it gets as to how well one works. With that said even if the heat they put out is low they do still give out some.
A 12 volt electric heater can never replace a car heater but help speed defrosting along.
Everyone will have a different experience with 12 volt window defrosters, so be sure to read the reviews on Amazon or elsewhere to be sure a unit is a good fit for you.

    I reacenrtly had aford windstar that defroster issues (its the vent in sealed duct work
    wont open junk bad design.)
    I decided try one these defrosters such a thing should be avalible at all auto stores.
    Since I had one i loaned out years ago didnt get back it was a good heater only.
    So Harbor freight had one like mentioned it has a handle for portable use too.
    Driving at 25-30 mph in town at 30 degrees out side works but with rear heater off.
    On highway at 45-60 mph window fogs up it is same as others internally all case styles vary”
    so not totally useless but get’s 2 stars. It runs at 15 amp fuse draw on unit so you need a lighter socket wired to battery , as heaters will melt the thin 16-22 guage wire and pop the mini blade fuses @5 amp in your cars. Always use that one for phones and Gps , and small devices only. You should always have someone install a 12 guagewire to cig lighter socket from battery fused 10-15 amps when buying a new car.
