Again, online shops sell country converter kits -- admittedly most often
for US to whatever, but I've seen all-to-all kits (or nearly so).
Although a 220V version may come with all the converters needed -- one
would think that it would, as otherwise you're limiting your market from
If you can't find converters, you can always work directly with wires
and four receptacles (two male, two female) and make your own. PITA, I
agree, but I've done similar things myself on fairly numerous occasions
to get around wiring mismatches or to make it easy to insert things into
a circuit that otherwise couldn't be inserted.
Do not attempt this, though, without fully understanding How Electricity
Works and what is safe and what is not. 120 VAC can be deadly. 220 VAC
is even deadlier. Heck, 9V batteries can be deadly if you really work
at it. And aside from deadly (if sufficient current passes across your
heart) it's pretty easy to create spectacular fuse-blowing arcing
spatters of metal and/or associated burns and fires.
I personally don't mind doing my own wiring as electricity tends to stay
where it belongs because air is a decent insulator at household
voltages. It's plumbing I can't stand, because air (pressure) is
basically ground, and the slightest gap in the insulation (pipes)
produces disaster. But don't do it if you aren't completely comfortable
with it (and look for the converter plugs in any event first, as they
are by far the safest/easiest solution and I'll bet you can google them
up quite specifically).
