What Power Plugs and Sockets Are Used in China?
Mainland China is associated with Type A, Type C, and Type I plugs. Many hotels and newer buildings use combination outlet plates that accept more than one shape, but socket design and condition vary.
A plug that fits one hotel room may not fit securely in the next, so carry an adapter instead of relying on a universal-looking outlet.
Type A: two flat parallel pins
Type A is the familiar ungrounded two-pin plug used in North America and Japan. It is accepted by many Chinese combination outlets.
However, a polarized North American plug with one blade wider than the other may not fit, and a loose connection is a reason to change outlets or use a better-fitting adapter—not to force the plug.
Type I: angled flat pins with an optional earth pin
Type I has two flat pins set at an angle; the grounded version adds a third earth pin. It is the most useful target shape for travelers carrying a three-pin grounded device.
If your charger was designed to use an earth connection, choose an adapter that preserves it rather than converting the plug to an ungrounded two-pin connection.
Type C: two round pins
Type C, or the Europlug, has two round pins and is accepted by some combination outlets in China.
Do not assume every wall socket will take it, especially in older or simpler accommodation. Type C is also ungrounded, so it is not a substitute for a properly grounded connection.
China Voltage: Check Your Device Before Plugging In
Mainland China supplies 220V electricity at 50Hz. Plug shape and voltage are separate questions: an American Type A plug may physically enter an outlet, yet a 120V-only appliance can still be damaged by the 220V supply.
Check Your Device’s Input Voltage
Look on the charger brick, power supply, appliance base, or manufacturer specification for the word Input.
A label such as INPUT: 100-240V ~ 50/60Hz means the device can accept China’s supply; you only need to solve the plug-shape problem.
Do not confuse this with the Output line, which describes the low-voltage power delivered from the charger to the device.
What the input label says | Can it use China’s 220V supply? | What to do |
|---|---|---|
100-240V, 50/60Hz | Yes | Use a plug adapter only if the plug does not fit securely. |
220-240V, 50Hz | Yes | Usually only the plug shape needs adapting. |
110V or 120V only | No | Do not plug it in directly. Use a suitable converter or leave it at home. |
No readable input rating | Unknown | Check the model on the manufacturer’s website before use. |
A frequency mismatch matters mainly to certain motors, clocks, and timing-dependent appliances.
Electronic chargers labeled 50/60Hz are designed for both. If a device lists only 60Hz, consult its manufacturer even when the voltage range includes 220V.
High-wattage appliances need a separate check
Hair dryers, curling irons, kettles, and some shavers draw far more power than a phone charger. If one is 110V-only, a small travel adapter cannot make it safe.
Any converter must explicitly support the appliance type and have a continuous wattage rating above the appliance’s wattage; otherwise it may overheat or fail.
A dual-voltage travel appliance or a hotel-provided hair dryer is usually the simpler option. If a dual-voltage appliance has a manual selector, set it to the 220-240V position before plugging it in.
How China’s Voltage Compares With Other Countries
Whether you need only a plug adapter or also need to worry about voltage depends largely on where your devices were designed to be used.
China uses 220V at 50Hz, so travelers from countries with similar electrical standards may only need to solve the plug-shape difference, while devices from lower-voltage regions require closer checking.
This is especially important for travelers from the United States, Canada, Japan, and Taiwan, where common household voltage is lower than in mainland China.
By comparison, devices from the UK, much of Europe, Australia, and several Asian countries are generally closer to China’s voltage standard.
The table below shows how China compares with common travel markets and what differences may affect your devices.
Countries/Regions | Voltage | Frequency | Notes |
|---|---|---|---|
China | 220V | 50Hz | Standard across mainland China |
Hong Kong | 220V | 50Hz | Voltage is the same, plug type G used (different from China) |
Macau | 220V | 50Hz | Same as Hong Kong, plug type G |
Taiwan | 110V | 60Hz | Voltage differs from China, requires a voltage converter |
United States | 120V | 60Hz | Most devices not directly compatible with China's 220V |
Canada | 120V | 60Hz | Same as the US |
United Kingdom | 230V | 50Hz | Compatible with China's voltage, but plug shape is different |
Australia | 230V | 50Hz | Voltage compatible, plug type I also used in China |
Germany | 230V | 50Hz | Voltage compatible, plug type C needs an adapter in China |
France | 230V | 50Hz | Same as Germany |
Japan | 100V | 50/60Hz | Not compatible with China’s voltage—voltage converter may be needed |
South Korea | 220V | 60Hz | Voltage is the same, slight difference in frequency |
Thailand | 220V | 50Hz | Same as China |
Brazil | 127/220V | 60Hz | Varies by region—check your specific destination |
India | 230V | 50Hz | Compatible with China's system |
Singapore | 230V | 50Hz | Voltage compatible, plug type G differs from China |
Malaysia | 240V | 50Hz | Close enough to be compatible with Chinese voltage |
Choosing the Right Adapter for China
What to look for in a travel adapter
A plug adapter changes the physical connection; it does not change 220V into 110V. For a short mainland-only trip, a well-made adapter that accepts your home plug and outputs Type I is a dependable choice.
A universal adapter is more convenient for a multi-country itinerary, provided its rated voltage and current cover everything you plan to connect.
Check four features before buying:
Grounding: if your original plug has an earth pin, use a grounded adapter and a grounded outlet.
Load rating: the adapter’s voltage, current, and wattage limits must not be lower than the connected equipment.
Stable fit: retractable pins should lock in place and the adapter should not hang loosely from the wall.
USB charging: a built-in USB-C port is useful only when its Power Delivery output meets your laptop or phone’s requirement; plug compatibility does not guarantee fast charging.
A compact multi-port charger can reduce the number of wall adapters you need. It is one of the practical essentials for China travel, especially in rooms with only one convenient outlet.
What to pack for common home plug types
Home region | Common home plug | Physical fit in mainland China | Practical action |
|---|---|---|---|
United States / Canada | A / B | Two-pin Type A often fits; Type B usually does not preserve grounding. | Bring a grounded adapter for three-pin plugs and check every device for 100-240V input. |
United Kingdom / Ireland / Singapore / Malaysia | G | Usually does not fit. | Bring a Type G-to-China or universal adapter; voltage is generally compatible, but still check the label. |
Continental Europe | C / E / F | Type C may fit some combination outlets; E/F grounding usually will not. | Bring an adapter, especially for grounded plugs. |
Australia / New Zealand | I | Often compatible. | Check the voltage label and carry a compact adapter as a backup for variable outlets. |
Japan / Taiwan | A / B | Two-pin Type A may fit. | Voltage is the main risk: confirm 100-240V input or use an appropriate converter. |
South Korea | C / F | Type C may fit; Type F grounding may not. | Bring an adapter that preserves grounding when required. |
Where to Buy an Adapter in China
Buying before departure gives you time to check the specifications and test the fit. If you arrive without one, ask your hotel front desk first; some properties lend or sell adapters.
Airports, major train stations, electronics retailers, department stores, and larger convenience stores are other practical options, while local delivery platforms can work if you have a usable delivery address.
Before paying, check that the adapter accepts your exact plug, outputs a China-compatible shape, is marked for at least 220-250V, and has a current or wattage rating high enough for your equipment.
Avoid unmarked products, damaged housings, loose pins, or adapters that cannot hold your plug firmly.
Charging Devices Safely in China
Manage limited or unfamiliar outlets
Hotel rooms and hostels may have fewer convenient outlets than you expect. A compact power strip or multi-port charger can help, but it must accept 220V and stay within both its own rating and the wall adapter’s rating.
Do not connect high-wattage heating appliances to the same travel adapter or power strip as your electronics.
If an outlet is cracked, scorched, unusually hot, sparking, or too loose to hold a plug, stop using it and tell the property. Charge valuable devices with your own charger and cable rather than depending on an unfamiliar public USB port.
Power-bank rules for flights in and within China
Pack a power bank in carry-on baggage, protect it from short circuits, and make sure its watt-hour rating is visible.
Up to 100Wh is generally the simplest category, while larger batteries require airline-specific confirmation or approval and may be refused. Airline and route rules can be stricter, so check the operating carrier before departure.
There is an additional rule for domestic flights within China: since June 28, 2025, the Civil Aviation Administration of China has prohibited power banks with no CCC (3C) mark, an unclear CCC mark, or a recalled model or batch.
This domestic-flight requirement is separate from the battery’s Wh rating. Inspect the casing before your trip, and do not rely on a power bank whose label is worn away.
FAQ
1. What if my device doesn't have a label for voltage?
Do not guess. Search the exact model number on the manufacturer’s website or contact the manufacturer. If you cannot confirm that it accepts 220V/50Hz, do not connect it directly to a mainland Chinese outlet.
2. Are there any public charging stations in China?
Yes. Airports, train stations, shopping centers, cafes, and other busy public places often provide outlets, USB ports, or rentable power banks. Availability is less predictable in rural areas, so carry your own charger and cable and avoid damaged or loose sockets.
3. Do USB chargers need a voltage converter in China?
Most modern USB phone and laptop chargers do not, but the printed input range is decisive. If it says 100-240V and 50/60Hz, you normally need only a plug adapter. A USB-C port’s wattage still needs to meet the device’s charging requirement.
Conclusion
Preparing for power in China is mostly about checking your devices before you go. Make sure your chargers support the local voltage and bring a suitable adapter for anything that does not fit securely.
If your trip also includes Hong Kong, Macau, or Taiwan, check the plug and voltage requirements for each stop. High-wattage appliances and power banks may also need extra attention.
With the right adapter and a quick check of your device labels, keeping everything charged in China should be simple—leaving you with one less thing to worry about on your trip.
