Power & Charging guide
China Power Plugs, Adapters, and Voltage Guide
A guide to charging devices in China, covering plug adapters, 220V voltage, dual-voltage chargers, converters, USB charging, and safety checks.
Electrical compatibility depends on your device label and adapter quality. For medical devices, confirm with the manufacturer.
Quick answer
Check charger labels: 100-240V usually needs only an adapter; single-voltage devices need special care.
Use this practical sequence to prepare, act, and recover if the normal plan does not work:
- Check each charger or device label for input voltage and frequency.
- Bring a plug adapter compatible with China sockets and your home plug type.
- Do not plug single-voltage 110V devices into 220V without a proper converter.
- For medical devices, confirm power compatibility and backup plan before departure.
Applies to travelers bringing phones, laptops, cameras, hair tools, cpap devices, or chargers, visitors from countries using 110v devices, travelers depending on mobile payment and translation apps.

This answer was checked against Electrical Safety First: Travel adaptor for China and U.S. Department of State: China travel advisory and country information. A third source, Power Plugs & Sockets: China plug and voltage guide, was used where the answer depends on implementation detail or traveler-facing handling. Additional support from Trip.com: China plug and voltage guide was kept when official rules and platform execution need to be separated. Where sources use different scope or dates, the guide follows the current official or most directly authoritative source and keeps platform or traveler-facing material as implementation context only.
