We are planning a trip to Europe and I would like to take my Philips Norelco 482 XL Twin Head Shaver instead of my 1290X Triple Head Shaver to save the amount of weight I need to lug. Last time we went to Europe I destroyed an older (lighter) triple head Norelco by forgetting to move the switch from 120 to 240 volts. My 1290X automatically adjusts for the voltage I'm using to charge it. I cannot find a switch on the 482 XL, and I don't want to have to use a little plastic blade razor and all the gell stuff because I killed my shaver again. Does the 482 XL switch automatically or not?
