I had to buy a replacement adaptor for my vaio laptop so its just a generic adaptor. Is there something in specific im looking for on the specs?
If it works with your laptop here, and if it says it has 110 and 220 then all you need is the $9.99 thingie from Radio Shack. Take a close look at the laptop's power adapter you have.
If were are taking things like a blow dryer or phone charger...it would probably be a good idea to take the voltage transformer you mentioned???
Yes, and no.
A phone charger is an electronic device so you need the $9.99 thingie again. Just make sure the charger is 110 and 220. Most of the newer ones are.
For the blow drier, also check if it's dual voltage. Some of them are. If not then you'll need the $27.49 thing. Make sure that the wattage rating is sufficiently high. 1600W, like the one mentioned here, should be enough for most hand held hair driers.
