Most of the Philippines is 220 Volt 60 Hz mixed with the American and European plug. There is sometimes a ground in some areas. Americans will need a step-down transformer. It's best also to bring such items that work universally such as those electronics marked with a 100V-240V 50/60hz compatibility to avoid voltage concerns.
3-phase voltage is 380v.
Downtown Baguio (northern Luzon) uses 110 V, and is also 60 Hz. This doesn't extend beyond the center of the city. The airport, for example, is 220V. If staying in the Baguio area, always ask first! If your equipment is 100-127V, merely crossing a street corner can cause it to be damaged or even catch fire. There are no signs in Baguio indicating where 110V ends and 220V begins.
During drought seasons (March to May), most of the power-plants are hydro-electrics (as stated above in the climate section), regular black-outs happen during this time, ask if your hotel owns a generator.
