This is the dual fuel version of the same GasOne stove I descibed in an earlier posting. The only difference is the color of paint and a threaded gas intake for connecting the included propane hose / regulator. Currently running $10 more at $26.88 it is well worth the extra.
I set it up on propane and made my usual 15 oz. Mug of coffee. It took about 1 1/2 minutes. My clock does not display seconds, so a bit of estimation. The box claims 8000 BTU/hr which is about 2350 W and it was about the same time as the 3000W Lixada stove at less than full power but similar flame size.
It burns very evenly and quietly. The large 4 element pot support is easy to use. The fuel knob gives precise and smooth flame control. My impression is that the propane pressure is regulated to a bit less than butane at my warm room temperature.
The regulator cools noticeably in use, consistent with the idea of a pressure drop across it. The hose is very heavy duty.
My only concerns are that the fuel load / unload lever does nothing to propane. You must unscrew the canister. If you don’t then a stray bump of the fuel knob could let your tank slowly drain to empty. Also, having a chunk of hose and a propane tank taking up table space just is. For the ability to use propane too, that’s worth it.
I will likely use it on the butane canisters much of the time, just for ease of setup and table clutter. But for long cooking, like canning runs, swap to cheaper propane. I ran one 90 minute canner load on the other stove using butane and consumed over half a can.
Given the size and weight, not for backpacking, but car camping and patio use. For regular cooking, far more comfortable and familiar than camping stoves. This will be next to my BBQ come summer BBQ season. (My BBQ lacks side burners) This stove works well on tabletops and counters. Not too much surface heating and the flat shape makes a convenient cooking height with no tipping issues.
