Ummm not sure but I'll speculate that it's not a good idea. Here's why:But this is a subjective discussion about coffee; what I meant, was what do you think of a 12V - high-amp water heater...
1. Instant aint good. If I were to use instant I would use those little Starbuck tubes.sonof40, I am a bit surprised.
Let me explain: I do not see the problem with coffee, have you guys tried "Nescafe" it's a powder that you throw in hot water and you get American style coffee, no problems at all. It's a bit expensive but unless you camp 200 days a year, the convenience is worth the extra cost. With hot water, other people can make tea or (my favorite) hot water with honey.
In any case, the problem becomes how to quickly make hot water in the morning, when everything is freezing cold.
You use an inverter and a normal coffee machine like the ones in hotels. Inverters are quite inefficient; when I was young I did several tests because we had to carry car batteries to the mountains to run telescopes, and running everything through an inverter emptied a 60Ah car battery in a matter of two-three hours, while with a DC-DC converter they would run "forever"... the fact is that I wish there was a 12V water heater with enough power to boil water in seconds. It would need high gauge wires but 100-200A would make water for coffee boil in probably less than a minute. Unfortunately, it seems no ready solutions exist, what I found online was some stuff that takes 40 minutes to boil water.
What do you think?
Technically true but in practice, power inverters are in the 90% efficiency range these days so really there isn't much difference due to loss. Power is power converted or otherwise and you'll still need pretty much the same amount. The only significant variable is time and when it comes to me getting my coffee in the AM, I'm not that patient.Well but if you use an inverter to run a 110V appliance of similar power, you are going to draw more than 125A, because the inverter has inefficiencies. That is why I was advocating a 12V one.
Like I said in my practice, to boil 1L of water, a 1500W water heater takes about 2 minutes (so 120 seconds, lol) equated to 12V power this requires 125 Amps. Where as an average 2 burner propane stove take about 3.5 minutes to boil about 1L.Exactly, with an electric water heater it would take literally seconds to boil water even in windy areas where the propane stove takes FOREVER.

We must do very different kind of camping! :habbobuggs:just at a slower rate, so it will take longer to heat the water. Probably at that point, longer than the stove. So I'm still a stove fan. LOL
