Hey all, I have a Lenovo Y510P laptop I got in the US, but am in Spain for vacation, and cant charge my laptop for fear of the voltage difference (my laptop uses 170 watts, EU uses 240 watts). I dont know exactly what I need to convert the voltage correctly to not damage my laptop battery. A voltage converter or transformer? I dont think my laptop charger has any switch to change the voltage. Help! I need to get all my photos from my camera!
