Amps -V- Noodles

The Question is do I keep my Microwave oven for the crossing or do I ditch it.
Pro. It will cook my noodle dish in 3 minutes.
I don’t need to use boiling water which takes longer using gas.
Con. It uses 85 Amps to do this including the inverter.
It takes up space.
My math may be wrong 85Amps divided by 60 min X 3 min = 4.25amps

Did it really only use 4.25amps??

I just don’t understand this white man’s magic. e.g. 12 volt battery power.

Given the figures you have cited - if it draws 85 amps per hour at 12v
Yes. It really only uses 4.25 amps.

Simon, I really hope you don't cook noodles for an hour so:

If I've got this right, you say the unit uses 85Amps through the inverter when it's running. That tells me that it's an 85A x 12V = 1000W microwave. A 1000W microwave uses about 10A or so of mains power depending on the voltage (you didn't say but a bit irrelevant anyways).

If it's using 85A for 3min to cook your noodles thats 85A x 3min = 255A / 60mins = 4.25 AmpHours.

255 Amps to cook noodles?? Another way to look at it is: To put the power back, you'd have to recharge the batteries at 4.25amps for 1 hour to make up for a single plate of noodles. Not good if you're in the middle of nowhere!

A couple of cruisers that sailed to the south pacific had this suggestion: Get two of the stand up commercial coffee thermoses. The ones with the hand pump at the top. They would keep one filled with boiling water and one filled with coffee.

That meant they would only have to boil water once per day (I have one and they are REALLY efficient at keeping things hot) and could instantly access near-boiling water.

You could dispense hot water into a bowl with a lid, add noodles, and in 3-5mins you're eating.

I have a sauna on my boat, therefore I win.

I don't have room for a microwave...the Viking Range takes up too much space! Doesn't use any amp hours but makes quick work of the propane tank!

No longer posting. Reach me by PM!
