Less concerned about time and more concerned with State of Charge. The appeal of a 12v kettle is using the DC 12v port on your power bank and avoiding the efficiency loss of the AC inverter. It would be helpful to run the same test with 1/2 liter (Aka a large hot beverage) on a power bank from Jackery or Bluetti etc. Run the the first test as 12v DC at 100% state of charge and measure the capacity of the battery used. Then repeat from 100% state of charge using he AC inverter and see if the power loss from conversion to AC is made up for the shorter time requirement. So much power is lost to AC conversion so it is useful to find DC capable alternatives even if they are a little less convenient.

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.

Lets run a test then stop halfway through time-wasting fucker

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

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 …

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

What is the watage of the panels?

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

Comments are off on the Radio upgrade video. Can you tell me where you got the radio upgrade kit from? Thanks.

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.

I had a leak that over weeks emptied a bottle but couldn’t find it with fluid ,in the end I got an electronic detector and found it straight off,

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

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.

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

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

You saved my time and money, thank You!

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!

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

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.

Do you have any links or code for your radio for the ducato 2003 as I can't find it, looks good just what I'm looking for many thanks

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

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

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

Great way to drain a battery

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

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.

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

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

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.

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

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.

Very interesting.....🙃

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.

Picture this, you're driving a CAR with a BABY on board who needs feeding on a LONG journey, or your old MUM is gasping for a cup of tea? WE DON'T have the LUXURY of a CARAVAN. So would you rather wait 45 mins or go WITHOUT???????? DON'T KNOK PEOPLE WHO ARE NOT AS PRIVILAGED AS YOU. bunch of TWATS.

Excelent video, thanks.

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.

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.

Thank you

What are you spraying that makes the bubbles?

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.

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.

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

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

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.

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

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

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

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