12v kettle how long to boil

Arthur Brown Posted September 26, Lady Muck Posted September 26, Bunny Posted September 27, Posted September 27, Timleech Posted September 27, The auto off can't be used as a manual off, which is a bit annoying.

That will get water to boil. This means you need to do some research for your particular vehicle to see what the 12V socket outlet is rated for.

Divide , by and you find it takes the kettle about seconds to do the job, which sounds about right—an electric kettle generally does take about 2—3 minutes to boil. Why does it take longer to boil a kettle of water than to cool the same kettle of water to a lower temperature? That heat energy never gets to the water. Some heat energy is wasted heating up the metal of the kettle. The kettle has a power rating of W, which is about the maximum you can pull from a cigarette lighter or 12V power socket.

Before ordering make sure your cig lighter circuit has a 15A fuse fitted. Any comments? We def want some kind of windbreak as cooking in windy conditions was a mare. We did some cooking in the boot of the car at one point! Also thinking of a carpet just to make it more cosy. Then of course there is the need for a roofbox and bars so we can transport all the new things we want! The car was full! This is an old post, but thought I would add my findings, I have recently bought a 12v watt kettle ml capacity , it is fine for in car use, as I mostly use it for cooking noodles, which only requires ml of water although I do fill the kettle with mls, I use the kettle during my lunch break at work, as I am on the road all day in between client visits.

To boil mls of water from cold using a 12v kettle takes a shocking amount of time, 30 minutes or more if you are lucky, even longer if the water is very cold.

It's all down to physics really, a mains watt kettle takes around 2 minutes to boil mls of water. The way I use my 12v kettle is to fill it from my flask, so the kettle is getting a bit of a head start as the water from the flask is already at 90deg C, to be fair that is hot enough to make a brew, but really not hot enough to cook my noodles. To get mls of water to a rolling boil it takes my 12v kettle just 7 minutes, which works fine for me. Another consideration is the current a 12v watt kettles draws around 15amp, even though many cars have a 20amp fuse for the 12v outlet, the socket and the wiring may not be able to cope with the kettle and damage could be done, typically the 12v outlets on cars are rated at watt, watt, watt, and watt depending on the make model.

You can get lower wattage 12v car kettles, watt and watt I have seen, but they are just going to take even longer, although may be better suited to plugging directly into the 12v car outlet socket, so a compromise to be made I guess, if you don't fancy connecting the kettle directly to the car battery.

This in effect means that you have to run the kettle directly of the car battery, easy to do, but to save drain on the battery and to keep the boil time to a minimum, you are best to have the engine running. For camping you are far better of using a gas burner or better still EHU and a regular mains watt kettle.
