Or ask to be moved to a room which has 240V window air. [Linked Image]

"The idea is that you insert the two US plugs into GPO's around the room in a random manner until you found two on separate phases; ie. 240V."

Aussie, most US hotel rooms (at least in larger hotels) are derived from a 208/120 Y. If you try this and are actually able to get two phases, you will probably not end up with 240V.

Likewise with Marc's idea of using a NEMA 6-15 plug. These are often used on 208V circuits. I wouldn't try either of these options without first checking the voltage with a meter.

208 vs. 230!? Not a problem. There are places in the UK that suffer voltage drops below 200, and in Ireland that is quite common and everything runs just fine. Sure, don't try to run big motors designed for 230 on this - but all I am interested in is getting my shaver to get rid of the fuzz on me face! (as well as the other kit that needs simple charging), the slight depression in voltage is a shed-load better than trying to get things to run at just over half!

Good point. I suppose a 120/240V 3-wire service is more likely to be found in those small "Mom & Pop" motels with just a few rooms.

With switched-mode power supplies being common for so much modern portable equipment, 208V would work just as well though.

I've seen reports saying that in some parts of Spain at peak demand times the voltage can drop as low as 180V. [Linked Image]

Rural Italy, distant 220V line... measured voltage under load around 170. The Sony cassette player first played slow and then quit working until the voltage got up again...

In Ireland you'll DEFINITELY see lower voltages than the UK. The PoCo would be aiming for 220-230V... It rarely is over 230V. Anywhere I've measured is between 190something and 228V.

(Everything's specified 220/380V)

In rural areas with long lines you can get the odd weird dip, particularly if someone's invested in a new milking machine down the road!!

Said house in Italy was at the end of an ancient 220V line (was there in 1991 and 1992) far away from the transformer. The feeder was just two very thin looking wires on warped and weathered wooden poles...
In that area (Arezzo, Tuscany) it's not too uncommon to find houses entirely fitted with German sockets because there are many Austrian and German expats.
