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.

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!
