Plan to use a HotLogic and a 12v mug ? - UtahPam - 04-26-2019

I figure I can buy frozen dinners and frozen veggies and have a reasonably healthy meal in 2 hours ?

Maybe I will get a 12v kettle too?

Any opinions out there?

IMO you're far better off buying a single burner butane or propane stove and using it with pots and a kettle than trying to use electricity to cook with.

That is, unless you're planning on staying plugged in to shore power all the time, then go ahead and use 120V appliances instead.

It becomes quickly apparent when you are your own supplier of all electric needs that providing that power needs careful management and a frugal outlook.

I love my single burner butane stove. I use it inside the van for almost all my cooking (breakfast and dinner). I resort to my 2 burner propane stove for outside use when I'm  either cooking for a crowd or doing things like spaghetti sauce or chili because they take so long. I also bake on the propane stove outside.

Best buy on the butane stove is in Quartzite at K&B Tools during the winter but they're not THAT expensive even if you get it at W/M. Canisters are cheapest (app. $1.25 each ) at Asian food stores or at K&B.

I have yet to try a hotlogic but if memory serves they use 45 watts. The formula as far as my learning to realize how much of a dent a 120 volt AC appliance makes in your battery is to divide the wattage in AC by the voltage of your batteries (12 volts in most cases) so 45÷12=3.75. 3.75 amps. That is then multiplied by hours of use. 15 mins would be .25 30 minutes would be .5 45 mins would be .75

EXAMPLE 2 hours 15 mins would be 2.25.

I use a different formula. AC inverters (the device needed to make household voltage from a battery) are inefficient. Cheaper ones usually even more inefficient. So to allow for losses I use this formula. 120 volts 45 watts ÷ 10 multiplied by hours. 45 watts ÷10=4.5 4.5 Amps. 4.5 Amps X 2 hours= 9Ah (amp hours) This formula works for me mainly because the math is simple. Just move the decimal point one place holder to the left.

A single walmart marine battery rated at 125Ah is a very cheap solution. But remember a good rule of thumb on many batteries is to use half of that number so as not to kill the battery.  So 62.5Ah since it uses 4.5 Amps 62.5÷4.5=13.88
You could run a hotpot for 13.88 hours before the battery is basically DEAD. That's for one device. You need to budget your usage carefully unless you have a large bank of batteries and a large array of solar panels and possibly a gasoline or propane generator.

That being said it is definitely doable. Possible better alternatives are butane or propane stoves as has been mentioned instead of or to augment your needs. Remember there are cloudy days when the solar cant keep up with your usage, but as the song says every silver lining has a touch of grey. You can learn extra skills. One I plan to soon try is usually referred to as "thermos cooking" you can cook many stews, and marinara sauces, curries, etc that way using minimal fuel and a thermos.

In conclusion definitely doable. Might take extra consideration and moderation. A good idea not to rely on this method entirely in many cases.

As far as a 12V mug. I've tried that. Drained my (small) bank and I ate coldish soup for dinner. Unless 12v mugs now come with a thermonuclear attachment I'd use that only when driving to keep your coffee warm.

Edit: stupid error

Thanks for responding ....
I will have to double check on all the info you gave me.
From what I recall HotLogic is 12v and runs out of the cigarette lighter, that is why it can take up to 2 hour to heat a tv dinner from a frozen state.

I try to miss breakfast to keep my weight down so on the road I plan to use a 12v coffee mug and/or a 12v kettle

XERTYX

the above message is in response to your previous message,

the do make a HotLogic with a plug. The one I am considering is with the cigarette lighter.

Hi Almost There
Thanks for responding to my post!

I should have mentioned I will be traveling in a Prius.
I try not to eat breakfast so if I pop in a tv dinner and a bag of veggies in the HotLogic it will be ready in 2 hours.

A Prius is a hybrid car with a huge battery, I believe running 12v is just fine.


BUT I mus have my morning coffee so that will be a 12v mug or kettle.

Also I will have a cooler

Hi Almost There

A Prius is also a generator

which is different than most vehicles, there are tons of videos on it

Here is my personal theory on it. You have a vehicle that it will work in. So just go ahead and buy those items and try using them. If it works great. If it does not please you then sell them or trade them to someone else in the RV community.

Don't get so hung up on this type of decision making because you have a lot of other things to decide about. Too easy to get burned out waffling around with a hundred should or shouldn't
