I've got one, just a 120V, home-use thing, but it gets far hotter, faster than on my stove. Tends to have a cool spot in the very center, maybe 3" diameter, unless you circulate the wok, and you can't flame food by tossing it in the fire (which you can't really do on a residential stove, either). It's a decent approximation of a wok jet for home cooks.
If you really want to burn your house down flame your home wok, you can always get a handheld blow torch to do the finishing ignition. Could probably flame 1000 wok dishes for a single torch canister.
Which most people don't. Also I could buy a portable gas burner suitable for a wok and gas canister for less than the standing charge of gas for a year. Unless you are using a wok extremely often its not worth it.
I don't have a wok, high temperature cooking would be nice for a few things like searing steak though. But that can be done over a BBQ. Kinda want to try heating a cast iron griddle when the coals are still orange hot and searing steak on that. Although steak isn't something I cook very often partly because its really expensive. Presumably a fair bit less cooking time than the packaging recommends. I guess get the iron hot enough for the leidenfrost effect to start and then cook until nicely brown on each side and then take off the heat? With hot charcoal that would probably be something like 30-60 seconds each side.
