something stupid

Without a galley, I hope to use the
Magma to heat water for my morning coffee and the evening's freeze-dried
meal.

I would buy a cheap 3000 watt inverter from Harbor Freight or equivalent and bring an electric tea kettle. You can very efficiently boil a few cups of hot water quickly and easily. A good 12 volt group 24 or above battery should easily handle this load (1500 watts divided by 12 volts = approximately 125 amps--for 5 minutes = 10 amp hours from a battery which should have 70 amp hours or so of capacity.) If worried you could always leave the engine running on high idle to put in 40 amps or so while using the tea kettle. If you want to spend a bit more and make it more robust install two new 12 volt batteries in parallel for one engine(or a large single Odyssey battery) and wire the inverter to it and also buy a $79. microwave and you can do a lot of cooking with a microwave, tea kettle and your Magma grill. With two new and identical 12 volt batteries in parallel you should be able to easily do 15 minutes of water boiling and/or microwave cooking
and use about 25% of the batteries' capacity which would be replaced in the first hour or two of running the next day. HEating water on a propane or charcoal grill is slow and consumes a lot of gas or charcoal to do so.

Another option would be a pump type primus stove. Coleman used to make them. Hyper efficient .
Purchase #1 when I was a young Royal Marine, so that you could ditch the navy issued hexy blocks.
