Most modern computers, cameras, and smart phones have built-in, automatic converters. If the power block (the little black box that you plug your electronic device into and then plug into the wall) indicates it can handle an input of 100-240V, or if the equipment or power block is stamped with the symbol "CCC," then it will work anywhere SRAS offers programs so long as you have a plug adapter. an adapter with a fuse - which is highly recommended. Apple travel adaptors will cover you as you travel and should have no problems. If you use another adapter, make sure it indicates that it will work in Central/Eastern European areas and, if it does not already contain a fuse, purchase a separate surge protector.
If your electronic device does not indicate this symbol or this input range, you will likely need a full voltage converter. However, you should check and double check the device's requirements. Plugging an unequipped device into a foreign power source will damage it, often irreparably. Likewise, plugging your a device that is equipped with a voltage converter into a separate voltage converter creates a fire hazard and can also damage your device, sometimes irreparably. If you have any doubt, contact the device manufacturer and ask what you should do.
