United States plug types & voltage — adapters, 100–240V devices and local sockets
The US uses Type A (two flat pins, ungrounded) and Type B (three-pin, earthed) sockets at 120 V/60 Hz.
Sockets & supply
Type A/B sockets at 120 V/60 Hz. Flat-pin plugs fit; 220 V appliances need a transformer.
From China — your plugs vs local sockets
On the ground
The US uses Type A (two flat pins, ungrounded) and Type B (three-pin, earthed) sockets at 120 V/60 Hz.
Dryers and ranges run on 208/240 V dedicated circuits, but ordinary wall outlets are all 120 V.
What to pack
Chinese flat-pin plugs fit as-is; single-voltage 220 V appliances need a transformer. Skip packing a hairdryer — hotel units are native 120 V anyway.
Two-pin outlets in older homes carry no earth — grounded three-pin gear needs a Type B outlet or a proper earthed adapter.
Wide-voltage (INPUT 100–240V) chargers and power bricks work anywhere; single-voltage heating appliances (hairdryers, kettles) need a transformer when voltages differ. Country data cannot certify a device — check the nameplate.
