Who This Helps

  • 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.

Before You Start

  • 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.
  • Avoid overloaded adapters and damaged cables.
  • Keep one charging cable and small adapter in your day bag.
  • Combine this with a compliant power bank plan if flying domestically in China.

Common Failure Cases

  • My phone charger says 100-240V. Use a suitable adapter and avoid cheap unsafe extension blocks.
  • My hair dryer says 120V only. Use hotel equipment, buy local, or bring a proper converter rated for the wattage.
  • The official source and a platform or staff answer do not match. Follow the more authoritative official or on-site source, keep screenshots or documents, and choose the lower-risk fallback until the conflict is resolved.

Source cross-check

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.

FAQ

Do I need a converter for a laptop?
