China runs 220V at 50Hz and accepts three plug types: Type I (its own grounded standard, near-identical to Australia), Type A (flat blades, common in older buildings) and Type C (Europlug). US single-voltage devices need a converter; the plug may fit (Type A) but the 220V will damage them.

China outlet FAQ

Can I charge my phone in China without a converter?

Yes. Phone and laptop chargers are dual-voltage (100–240V) — you only need a plug adapter.

Is 220V dangerous for US devices?

Only for single-voltage (120V-only) devices like hair dryers — those need a voltage converter. Dual-voltage gear is fine on an adapter.

What plug type does China use?

China uses Type A/C/I sockets at 220⁠V / 50⁠Hz.
