No need to rely on hearsay. Take a close look at your devices' power supplies. You might need a bright light and a magnifying lens to read it, but each supply has its input power specifications printed on it. Nearly any device made in the last ten years will say something like "Input: 100-240V 50/60Hz", which covers every wall outlet in the world.
