If you live in a country where the AC line voltage is 220 Volts AND if you live in an area which is sometimes quite hot (France in the Provence) AND if you have a trafo 220/110 for your many pieces of American computer equipment, THEN it is recommended to use that trafo for your power adapter. When connected to 220 V it will get quite hot, although I experienced no problem even under the severe condition.
