that's odd. Nowadays consumer electronics are multi-voltage. Strange yours don't adjust automatically. This being said, for most light application like notebook etc you will find 220V-to-110V converters at electronics outlets like FNAC and Mediamarkt (explain transformateur, pas adaptateur). If you need heavy-duty kinds, like drawing over 25W (i.e. your hairdryer or dishwasher if you were silly enough to carry it here) you need to go to Balsiger SA (google it). That will cost you about 200-300 CHF. The contraption weights about 5kg and is ranges from stapler to ski-boot size. 

laptop chargers can be generic. Just find one that has the correct size plug. Doesn't need to be the same brand

Any chance you would know where I would be able to buy laptop chargers?

Wendy,

SwissKiss is right, check on your laptop charger, on the back to see if it is 110-240v? nowdays most IT computers/laptops equipment is munlti current. Printers are mostly 220-240v. And also some TVs. Other are If so, then the conversion works automatically and no need for a converter. Always check the back of the appliance to see what is theWattage, this is where you can cause alot of problems. Most appliances in Switzerland are like 220-240v, 50/60mhz.

Swisskiss is right, converters are really expensive, i tried this when I also came, but then found that it was much easier to just buy new stuff. Because :

Few appliances got fried

First cheep converter started on fire

Second converter just go so so hot, i could smell it.

An most of all, dont use converters for anything with high currents, like Microwave, Hair dryers, washing machines, dishwashers. Because the heating elements pull alot of energy, get very hot, and could burn your circuit breakers, where you will then have to pay for an electician.

I believe that Interdiscount sell generic laptop chargers, otherwise I would try www.1000ordi.com (very good for all PC components and they have a shop in Carouge) or Amazon (the German site is easiest for deliveries).
