China to US plug adapter guide
Type A and I sockets in China, Type A/B in the US, and voltage advice for Chinese travellers. Travelling from China to the US, many Chinese Type A plugs (flat two-pin) fit US sockets directly — but Chinese Type I plugs (angled) need an adapter. The bigger issue is voltage: China runs 220V, the US runs 120V, so check your devices carefully before plugging in.Quick answer Plug: China uses Type A (flat two pins) and Type I (angled pins). Type A fits US sockets directly. Type I needs an adapter. Voltage: China is 220V; the US is 120V. This is a significant difference — check every device label. Frequency: China uses 50Hz; the US uses 60Hz. Fine for most electronics.
| China | US | |
|---|---|---|
| Plug type | Type A/I | Type A/B |
| Voltage | 220V | 120V |
| Frequency | 50Hz | 60Hz |
| Converter needed? | Check device label — voltage difference requires attention | |

What plug adapter do I need from China to the US?
Whether you need an adapter depends on which Chinese plug type your devices use:
- Type A (flat two-pin) — fits directly into US sockets with no adapter needed. Many Chinese phone chargers and laptop bricks use this shape.
- Type I (angled three-pin) — does not fit US sockets. You need a Type I to Type A/B adapter, available at Chinese airports and electronics stores before departure.
A compact universal adapter covering China's plugs and US sockets is the simplest solution if you're travelling with multiple devices. Look for one that specifically lists both China and North America on the packaging.
Do I need a voltage converter for the US?
This is the more important question on this route. China runs on 220V; the US runs on 120V — nearly half the voltage. Running a 220V device on 120V will not damage it, but it may not work properly (motors run slow, heating devices take longer or don't heat sufficiently).
How to check your device: look at the label on the charger or power brick. If it says "INPUT: 100–240V", it is dual voltage and handles both 120V and 220V automatically — no converter needed, only a plug adapter.
Most modern Chinese electronics — phone chargers, laptop power bricks, camera chargers — are dual voltage. Devices that may not be:
- Older Chinese appliances not sold internationally
- Hair dryers without a voltage switch
- Electric shavers designed only for the Chinese market
When in doubt, leave the appliance at home or buy a step-down converter (220V to 120V) before travel.
What if I forget my adapter?
US airports, electronics stores, pharmacies (CVS, Walgreens), and hotel front desks all stock basic international adapters. Target and Walmart carry them in most locations. Expect to pay a small premium versus buying before departure in China.

Do Chinese phone chargers work in the US?
Most modern Chinese phone chargers are dual voltage (INPUT: 100–240V) and work fine on US 120V power. Check the label on your charger. If your plug shape is Type A (flat two-pin), it fits US sockets directly. If Type I (angled), bring a small adapter.
Can I use my Chinese hair dryer in the US?
Probably not without a converter. Most Chinese hair dryers are designed for 220V. On US 120V power they will run at reduced power or not heat properly. Either bring a travel hair dryer rated for 100–240V, or use the one provided by your hotel.
