China: a familiar socket carrying 220V.
Chinese wall plates are the most permissive in Asia — many carry a flat-pin Type A opening alongside the angled-pin Type I opening, so US flat pins often drop straight in. That is the trap: every one of those holes delivers 220V at 50Hz, roughly double what a US-only appliance expects.
Three plug types on one wall plate
Type A is the two flat parallel pins Americans know. Type I is two flat blades angled into a V plus a vertical earth pin — the same family Australia uses, though pin dimensions differ slightly and a snug fit is not guaranteed either way. Type C, the European two-round-pin plug, turns up in older fittings.
| Socket you will see | Takes | Earthed? | Practical note |
|---|---|---|---|
| Type A (two flat slots) | US two-prong plugs | No | Your charger fits — the socket is still 220V |
| Type I (V-shaped, three pins) | Chinese and Australian-family plugs | Yes | The national standard for anything grounded |
| Type C (two round holes) | Europlug two-pin | No | A Europe adapter covers this opening |
| Voltage / frequency | 220V, 50Hz, on every opening above | ||
The five-second check that decides everything
Read the input line on the device. If it says 100–240V ~ 50/60Hz, China's 220V is inside its design range and you need a plug adapter at most. If it says 120V only, or 110–125V, it cannot go into a Chinese socket without a transformer — the fact that its plug fits is meaningless. Every USB-C charger sold in the US passes; hair dryers, curling irons and travel kettles routinely fail.
What to pack for a two-week trip
Type A openings are widespread, so plenty of US travelers get through China with no adapter — a gamble on the rooms you end up in. A Type I adapter costs almost nothing and removes the question. Pair it with one multi-port GaN brick so a single socket runs your whole kit.

Safe as-is, and the short list that is not
Safe: phones, tablets, laptops, camera and drone battery chargers, e-readers, electric toothbrushes, cordless shavers, portable power banks and every USB brick with a 100–240V label. These need shape, not transformation.
Not safe: a US-market hair dryer, flat iron, curling wand, travel kettle, corded coffee maker or any 120V-only motor. On 220V a resistive element draws about 3.4 times its design power and fails within seconds. Replace them with dual-voltage models rather than hauling a converter — the reasoning is in voltage converters vs adapters. If you are flying on with spare batteries, check the airline rules for chargers before you pack them.

FAQ
Will my US plug fit a Chinese socket?
Often yes. Type A openings that accept two flat parallel pins are common in China, so a US two-prong plug goes straight in. The socket still supplies 220V, so only dual-voltage devices are safe in it.
Is 220V going to damage my phone charger?
No. Any charger whose label reads 100 to 240 volts is designed for 220V mains. Chinese voltage is inside its range and it will charge at its normal rate.
Does an Australian adapter work in China?
Usually, because both use the V-shaped Type I arrangement, but the two standards specify slightly different pin dimensions so the fit can be tight or loose. An adapter sold specifically for China is the safer buy.
Do I need a voltage converter for China?
Only for single-voltage appliances with heating elements or AC motors — hair dryers, curling irons, kettles. Everything with a USB-C or USB-A port on the end runs on a plug adapter alone.
