what the voltage for us and philippines
1. Power Compatibility. The Philippines generally uses 220 volts at 60 Hz with U.S. style flat blade attachment plugs (symmetric). In a few cases, buildings also have 110 volt wiring, mostly used for air-conditioners, of which you have to be aware. Using equipment at the wrong voltage is a sure way of destroying them.
Many travelers to Europe have had difficulties with their electronics, because European and American power systems are run differently. Most of the world, including Europe, uses a 220 volt/50 hertz system. A handful of other countries, including the United States, have 110 volt/60 hertz electricity, which is believed to be safer. As a result, appliances in these nations are designed to connect to a specific type of power source, and using American devices in European outlets and vice versa can result in havoc.
