Voltage: 220 Volts AC, 50 Hz throughout China, including Guangzhou. Most modern electronics handle 110-240V input, but verify your device before plugging in.
Plug Types: China uses primarily Type I plugs (two angled flat pins) and Type A/B plugs (three rectangular pins in triangular arrangement). Some older outlets may use Type C (two round pins).
Adapter & Converter Recommendations: Universal travel adapters covering Type I and Type C are essential. Purchase adapters before traveling or at airport duty-free shops. Quality matters for multiple/expensive devices. Consider surge protectors with multiple outlets for hotel room charging.
Using Appliances: Check voltage compatibility before using hair dryers, electric shavers, or other heat-generating devices. Many hotels provide adapters at front desk upon request. Bring adapter redundancy since backup adapters are difficult to find mid-travel.
