My phone charger says 100-240V.

It is likely dual-voltage and usually needs only a plug adapter. Use a suitable adapter and avoid cheap unsafe extension blocks.

My hair dryer says 120V only.

It is not safe to plug directly into China’s 220V supply. Use hotel equipment, buy local, or bring a proper converter rated for the wattage.

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.

Updated 2026-06-27

Quick Summary

Check charger labels: 100-240V usually needs only an adapter; single-voltage devices need special care.

Direct Answer

China uses 220V supply voltage and 50Hz. Most modern phone, laptop, camera, and USB chargers that say input 100-240V only need a plug adapter, not a voltage converter. Single-voltage devices, many hair tools, and some medical devices may need a proper converter or should be left at home. Check every device label before travel, bring a reliable adapter, and avoid overloading cheap multi-plug devices.
