How bad does a 12volt kettle suck?

How slow does a 12v kettle boil? is a Gas hob kettle faster? what about a low power mains voltage kettle? how do they compare to a normal mains kettle? Can you predict the results?

[@bantrump9594]

It is not because of the voltage, but the wattage. You can buy a kettle with a high wattage if it is available. There are 12 volt cartridge heater/rods/coils that have above 1kW power. Many 12volt kettles have lower wattage because people are using them buy plugging them directly to one or a couple of solar panels. Unless you have a large solar system, you really want a low wattage kettle even though you need to spend a lot more time boiling your water. I believe your 12volt kettle is 300W. Most 120 volt home kettles are now 2kW. Therefore you need 8 times more to boil your water. In a power outage situation, if you don't not have a large electric generator, you can't get much power, so a low wattage kettle is actually better.

[@BakaNewsNetwork]

Yeah , 12v kettle is designed to be used on Low wattage output device, like Small solar system as you say and cars because most of cars plug wont allow much watts at output. I have a Small heater to put in a cup of tea, it take 5-10 minuts for Booking 250ml but i use literally no power , solar only.

[@fromtheflightdeck252]

Really? 1000W 12v heater?? Only 83 Amps?? Sounds great!

[@Juliadancecore]

Hi what size generator would I need to boil 600 wat 240 kettle for my motorhome any help appreciated

[@petebronsen6455]

Yeah you'd need to hardwire directly to your battery with 4 gauge wire to get 1000w

[@Juliadancecore]

We bought a 6000w car convertor and it works a treat in the motorhome, also bought a power bank it boils the kettle in 10 minutes so was useful to buy both convertor and power bank.

[@inthetigerseye]

Thank you so much for making this video. It was exactly what I was searching for!

[@richardellard]

With that IR thermometer, you were reading the surface temperature of the plastic exterior of the kettle.

[@adamdominik7579]

You saved my time and money, thank You!

[@PossumMedic]

Great vid thanks! It would also be interesting to see how much gas, or battery power each use.

[@frans_d7989]

I also had a 12v kettle in my van and had a similar problem that it took for ever to warm up the water. I found that the cigarette lighter power socket had a huge voltage drop and thus greatly reduced the power to the kettle. To overcome this problem I connect twin pair 6mm2 solar cable with a 50 Amp fuse directly on the battery and Anderson connectors on the kettle. It now boils in about 20 minutes. This was fine while traveling but still far too long while taking a break from driving and wanting another cupper. I have now dumped the kettle and put into the van 1.2KVA /230V inverter with a 100 A/H lithium battery that is charged from a DC to DC converter from the alternator and a 700W 230V kettle. It now takes about 5 minutes to boil the water and it also runs the toaster and the induction cooker on lower setting.

[@roadrunner8488]

Yeah I did the same, straight from the battery and was OK for the road trips

[@rhyannone]

This video just made my day! Just received my travel kettle, rushed to test it in the car, all excited, 40 mins later, car running, 350ml of water, and still tepid! What a load of rubbish they are. LOL, So glad you did this test, I will just use my camping gas cooker, maybe if I stick the kettle on, whilst travelling to the camp site, it might have boiled a few hours on !! Thanks for the video, it made me laugh with the irony of this daft kettle.

[@adam091080]

thank you saved my money! I have had a cup of tea from a van life girl who made it in her 12v kettle mug - it did take about 1/2 an hour but we were stealth camping and trying to be descreet so the wait was worth it in the end

[@willpablo]

Excelent video, thanks.

[@steveb5367]

Fantastic short but informative vid. You just saved me some money on doing this experiment myself. I guess they could re design a 12v product simply as a low volume water heater that you have switched on whilst driving so you've got some hot water when you stop, but as a kettle for instant convenience? Not really. I would love to see more vids like this with different types of product, inverters and how this effects battery life and performance.

[@TheEarthandyou]

Thanks a million. Still I wonder how long to boil one cup of water in the lame 12 volt kettle.

[@aalktebiify]

Thank you

[@linz_in_NZ]

Would one of the Waeco Kettles be any better, they seem to have a much thicker cord on them so might be better? My portable gas hob boils much quicker than your fixed hob for the same amount of water in a similar kettle - and that's not on full flame.

[@mikeysonlyvanspage]

Thanks for this video. I was just about to buy one on ebay to save on gas but maybe not now lol 😅.

[@charlesfeatherstone6196]

How much did the gas kettle cost you? The 12 v cost nothing.

[@Curtis.Carpenter]

adorable Dog, Hello George!!! my mini-bull Bronco says hello! 🐕

[@logothaironsides2942]

Iv'e got a flask kettle of about 220ml which runs on 12 volts and takes around 20 minutes to boil. You can just about get two small cups of tea from it or enough to add to a noodle meal or large coffee.

[@mas921]

My goodness glad I saw this before getting a 12v kettle. Yikes!!

[@GEAUXFRUGAL]

I've got a double wall 120V~ electric kettle. Not all kettle are equal, I'm good with electric. Have propane for when power is out.

[@richardabazley]

Very interesting.....🙃

[@howlinblues]

It’s for a 4WD or Car 12 Volt Kettle Timing is a must Water boiled in 40minutes No rush Tea Coffee ready 40 minutes for Travelers …

[@charlesfeatherstone6196]

What is the watage of the panels?

[@hannesjohannes2281]

i think i can build a better 12v kettle with only 4 diesel melting hot glow plugs.

[@furnituredoneright6375]

Pretty simple minded review, 12v kettles are great and you can halve the boiling time if you know what your doing. You wouldn’t have them in your home kitchen but if your camping or work from your car (tradesmen) they are great. If your looking for the stress free life of camping or traveling in a motor home but are to impatient to wait for your hot water probably best moving back to the city so people who really want the stress free life won’t have to listen to what you think of a product just because you can’t wait for a little hot water heated free from the sun.

[@crazycrab8578]

love your reply, its true, I use a 96 stove, you have to set it up, prime it, get it going, kettle on, wait around, make a brew, no rush, so what, it takes 20mins, you get there in the end

[@steff1193]

Thank you. I drive trucks and I am looking for a way to make tea and soup while I’m on the road. I guess this isn’t a good solution.

[@solarjinx]

Same here.

[@crazycrab8578]

the 24v ones are a lot better, more watts, the 12v ones only go to max 180wats, I got a 12v one made in the 80s, it takes around 20mins, that driving,

[@abdul-q-khan]

Thanks for reviewing it you saved me from wasting my hard earned money 💰.

[@bigbadaboomboom]

I have the same one. 20 mins when plugged into a car cigarette socket

[@jharish9330]

It is useful at time emergency to solar panels at the time of ----.and also I doubt about cable and power socket.

[@tangolima4148]

I have to say, the science on this subject is funny. No info on the 12V output wattage, the 230V kettle was boiling for a while before it ticks off automatically. A bit silly to read the time when it ticks off. A whistle kettle would have been whistling for a while there… All in all a bad show. The point is clear, but the science pretty bad.

[@mikkveere1409]

Buy a 12v coffee maker? Heats water aswell as much as needed. It never had to boil to get your drinks done. You only need to feel it with your hand and you will understand when it is right temp. best part, you do not need to wait for it to cool down as long. 50+degrees is enough to get tea or 3in1 coffee done. So what if it takes 30 minutes? Totally free energy... i think independence is worth it really!

[@dm.2023]

I bought a 12V drip coffee machine. It would take less time to leave the campsite for the nearest Starbucks and back before the 12V coffee machine has even produced the first few drips of coffee. Horrible purchase.

[@El_Chompo]

Those gas kettles could warm up just as fast if the firsts flames weren't so wasted flying up around the outside of the kettle

[@El_Chompo]

If you could make a kettle inside of a kettle, and then put it on the stove so that the gas goes up and through the space between the inner and outer shell, way more of the energy would be absorbed and it would be much more efficient.

[@daviddouglas4200]

Only have to look at the power cable ( 12 volt kettle ) to see its ........... !

[@PeterStokes]

And I guess the socket will have a limit on amps too.

[@chris-jb5ds]

I have a 12v kettle and 750ml of water takes 4m 31s But its 12v 300w and the cable is 2 x 2.5mm and it has croc clips rather than a ciger plug

[@AK-ho5xo]

What kind of kettle is that? The one I have at home (580W, 230V AC) brings 400 ml to boil in 6 minutes. How can then 300W bring almost twice more water to boil faster??

[@yemisiaderuku2902]

Mine takes 45mins too Exactly like the one in the video 12vol 150w

[@ebikecnx7239]

What brand is it? My 500ml capacity 1000W UNOLD travel kettle takes 3 minutes on 230v and 6.5 minutes on 120V. Any 12V 300W should take 10 minutes to boil 500ml and your 750ml would take longer so it doesn't add up. You have crocodile clips as if it were connected to the "cigarette" socket it would blow the car fuse as they are only 8A to 10A output (120W max.). Connecting to a solar panel directly would be best, on a sunny day, as the higher volts of solar direct would boil faster.

[@ebikecnx7239]

@@AK-ho5xo agreed. My multi voltage 110/240v UNOLD 1000W 500ml takes 3 minutes on 230V and 6.5 minutes on 110V. No 300W kettle could beat that..

[@RevGunn-jq3cq]

Great way to drain a battery

[@techtinkerin]

These folk probably boil it and go oh no it's too hot I'll wait for it to cool.

[@Ignisan_66]

All 12V kettles for regular cigarette lighter socket are total crap. To even get to the level of 1500 watt american kettles you'd need to have a ridiculous 125 amp current on 12 volts.

[@crazycrab8578]

I have a 12v, 160watts, one, it takes 20mins to boil, while driving, I time it so that when I get to my tea break time, hot water,

[@RealJohnnyDingo]

I have a 12v rice cooker, 100w, takes about 15-20 minutes to boil a cup or two of water. if I have an inverter hooked up I can run a regular 120v kettle (600 or 1200w), which still isn't as fast as that Australian 2200w monster!

[@RealJohnnyDingo]

crap is kinda harsh, they're doing as well as they can with the limitation of the cigarette lighter plug. it would melt with more power, or blow the vehicle fuse. it will eventually boil but it certainly takes a while.

[@SANTO971]

You are wrong. It takes 90Wh or 330kJ of energy to bring one litter to boil. So 300W @ 12V should heat up within 20 minutes. But with 90% efficiency required power increases to 200Wh and with lesser efficiency comes a point it is impossible. You need a thermos type water kettle to make it work perfectly.

[@myusername111]

All of the comments are just armchair electricians with basic knowledge trying to correct each other with day 1 facts

[@jamsessionrecordshop8872]

I thought you were going to say "the dog has died of old age" since it took so long for the 12v to heat up....lol

[@1FlamyAmy]

12 v kettle aren't worth buying. It blows a 20 amp fuse every time
