Hey there

Anyone do any 12v cooking with 12v appliances?
I see you can get an oven which uses 100W at 12v
I also see there is a kettle which heats 0.750ml of water to boiling in 30 minutes.


I am going to be hooking up a 12v system in my tiny house i figured i would ask here about 12v cooking!

Any other devices which work well using 12v?

My husband is a retired truck driver, and he used to have a 12V kettle for heating water and a 12V one-person crock pot. They were fitted with a plug for a cigarette lighter. If you research small appliances for truckers and RVs, you'll find quite a few options, I think.

Hi Jordan.  We run almost everything 12v. Freezer/fridge, lights, fans, heater, water heater, animal water heaters, pumps, corn sheller, grain grinder, and lithium chargers are just a few.  Here are a few pics of the fridge and little systems.

Thanks for this thread; I'm just now getting started building out my 12 volt DC micro-grid setup. As for your product question, I supported GoSun's latest crowdfunding campaign & got their 12 volt cigarette lighter plugin "Brew: Travel Coffee Maker" along with the rest of their "solar kitchen" setup which included a 12 volt DC refrigerator / freezer combo (the Chillest).

GoSun wrote:Stainless Steel Travel Mug, French Press & Heater All-In-One, makes tea or coffee anywhere in just 10 minutes.


I just got it in recently & I've used it already & it works well. In addition to being a 12volt DC device, what I like about it is that it's actually 3 widgets in 1: a kettle, a french press for coffee or tea, & a travel mug!

Check out the direct solar cookers that living energy farm uses, I think they call them roxies. I see nomreason they couldn't run on 12v, just need bigger wiring. Control would definitely be easier at 12V.

If there's a real Truckstop around where you live, go take a visit over in the Trucker parts area.  There's always interesting 12 volt stuff there.

12V DC cooking is going to be a bit rough as the standard plugs can only pull 100-200 Watts safely.  

Hot water is sorta like one step of cooking, a 12V DC heating element for a hot water heater would be useful.   There are on demand or not 12V DC kits for that.

There are apparently some DIY sous vide rigs for the googling.

I have a 12V DC LiFePo bank ( they are getting much more reasonable now a-days , and don't off gas when charging so they prefer to be in the house rather than in a vented compartment out in the cold.   I use it and an inverter to run an instant pot and a rice cooker, today I ran them at the same time... it was lovely.

Price wise, converting 12V to 120Vac ( always get sine wave inverters, it's just for the best ) is getting cheaper and cheaper.

I'm a big fan of Bob Wells at the youtube channel CheapRVliving.

And they just posted : Cook in Your Car! 12 Volt Electric Oven Cooking in Any Vehicle! Cooking & Warming with NO Propane!



At the end he messed up the units a bit.   The cooking probably took about 250 watt  hours, or 22 amp hours on a 12vdc system.   That'd be a lot of hurt on a lead acid system.   On a LiFePo, system i'd probably be fine.  Extra fine if you can do it while the sun is out on a few 100 watt pannels.

Bob also mentioned 'wrapping it up' e.g. like a hot box / hay box cooker.  

The given solution depends on situation and budget both in the longer and shorter term.

A $50 cooker that ends up eating $200 batteries every year or two due to deep discharge... not the best plan in the long term, and sometimes you need to do what you need to do.

Can't stop running into awesome 12VDC things....

https://gosun.co/collections/solar-ovens  and https://gosun.co/products/fusion-pro  , which apparently has a 12VDC option.


I have one of the originals packed away, it worked last I knew it was just a bit small for my needs.

I have no personal experiance with the current crop of products ( thought the website is being a bit... wonky for me ), I hear good things from a nomad I watch on youtube.

Might work out for you.

Good luck.
