Portable Instant Car Heater


Why freeze while you wait for your car's feeble heater to warm you?

Never again if you have this nifty device.

From the website:

    Add speedy warmth to a cold car, truck or van!

    Plug this portable heater into your car's cigarette lighter and its quiet, powerful motor and fan quickly heat and circulate air to warm feet and defrost windows in seconds.

    Rests on dashboard, floor or rear window deck.

6.5"L x 5.5"W x 2.25"H.

5-foot cord included.

Too bad there's no USB connector 'cause this would be great in a chilly office plugged into your computer.


$19.98 here.

Of course, leave it to Dan to ruin all of our fun and dreams with some amp/volt/watt formulas.

Where can I get a car heater running at 12V and 10 amps?

No of the major auto stores carry anything under 12 V at 20 amps.

I read your blog often and I have tried a fair number of products that have appeared. My favorite is the Swiss Victornox (sp?) travel suitcase. That thing is solid and has been a wonderful travel companion. What a price it was too! Folds up suits nicely and you can get an easy three days clothes in it. For a not so happy happy tale, I bought the tiny plug in car heater instead of fixing my Volvo, thinking I could get through the winter without making the repair. Sadly, compared to this heater, my computer would do a better job of heating the car. I don't know what this thing was drawing, but it felt more like a couple of d batteries were powering it. Guess they were more worried about liabilities than producing real heat. Ah well, keep the research team cracking overtime for that review! Cheers! (PS Anyone want to purchase a tiny mini plug in car heater?)

Standard USB's only good for 500mA at five volts, or 2.5 watts; a poorly insulated human body at rest in a cold room can be thought of as about a 75 watt heater.

A cigarette lighter socket can deliver far more power. The cigarette lighter itself draws better than seven amps at 12 volts (more than 84 watts), and there's considerable extra headroom; the fuse is probably 10 amps. You could therefore safely run a 100-watt-plus heater from a cigarette lighter socket. To avoid blowing the fuse, this thing will draw less than 10 amps at 13.8 volts (which is what you get when the engine's running; it'll draw proportionately less at 12 volts). That could give you an easy 120 watts.

120 watts is a worthwhile rating for warming a car. 2.5 watts for warming a room, not so much :-).
