So... My apartment has been a bit too exciting lately. I have been trying to set up my home office computer in FRA on 220 which had previously been set up in SEA on 110.

First was the printer AC cord, not the printer itself. My HP printer is supposed to work on both 110 & 220, but a "pop" sound came out of the adapter followed by smoke.

Next was my Modem, bought here in Germany, made for 220, which had been working fine. When I plugged it into the 220 power strip it made an even bigger "pop" and smoked poured out.

Now I'm totally gun shy. I have a transformer but it won't do for all the appliances that need to be attached. Any suggestions on what I should be doing differently?
