Oly:
I'm going to guess that the new mini-microwave suffers from the same faults as the ones discussed before: (except for having it's own inverter.)
1. Too small an inside area for many uses.
2. Too slow to heat or cook anything up; simply not powerful enough. If it only draws so many Watts, and that's all the energy it's got available to heat with (minus the inefficiency of the energy conversion from electrical to heat.)
3. No turntable for even heating.
4. 110-120 vac means you need an inverter, generator, or shore power to run it. (Exception noted above.)
5. It's Overpriced! $130 for a microwave that won't perform with a $50 unit!
***********************
If you want quick, easy heat for hot water or heating wet towels, forget the electrical route, including the "coil in a cup" quickie college shortcut.
Get a single or double burner propane stove and blast away with quick, direct combustion heat from concentrated petroleum fuel.
No need for wiring, batteries, inverters, switches, fuses, or fussy circuits!
As long as you're going to be using it over a short period and watching it constantly to cook or heat water, you don't need to worry about CO2 build up, CO detectors, or propane monitors.
Just be sure to store the partially used canisters outside in a well ventilated area where the heavier than air vapors, should there be a leak, cannot collect.
It's cheaper and faster than an electric alternative, and one heck of a lot simpler, too!
No Surprise: The KISS Principle Wins Again!
