8A draw, 600mL capacity, 1 hour to boil water. For an 200Ah AGM setup...
Solar (and everything else about my rig for that matter) has been a bit of a journey over the years for sure. First I started with a Renogy 100W "suitcase" but given that I'm an engineer working full time with a laptop, cel booster, inverter, etc it just couldn't keep up, not even close. I'm...
12V drip coffee maker I imagine would work great but you can't get around the laws of thermodynamics. Those 12V cooktops and "ovens" only put out 150-250W, it'll warm food just fine but I wouldn't say you can easily make a meal with them. By comparison, even the cheapest single burner butane gas...
For just storing? Unless you live in Antarctica or northern Canada you have nothing to worry about. They can't accept a charge below 32 F / 0 C but they'll still discharge well below freezing.

Stove top ain't gonna work, even with a much larger battery bank and regardless of whether they're lead-acid or lithium. Looking at a few cooktops online it seems like even the lowest draw is going to be somewhere around 1200W. Provided your inverter can even keep up with that, for 30 minutes...
