USA Steckdosen (Typ A & B) & 120V / 60Hz Spannung: Adapter-Ratgeber

Type A & Type B Outlets (120V / 60Hz)

The United States uses NEMA 1-15 (Type A, two flat parallel blades) and NEMA 5-15 (Type B, two flat blades plus a U-shaped grounding pin) running at 120 Volts and 60 Hz. Travelers from Japan, Taiwan, and Canada use the exact same plug shape; travelers from Europe, the UK, Australia, and Korea need a simple plug adapter.

Dual-Voltage Chargers (100–240V) vs. Single-Voltage Hair Tools

Check the fine print on your charger brick: almost all phone, tablet, camera, and laptop chargers read 'INPUT: 100–240V ~ 50/60Hz' and work natively on U.S. 120V power with only a passive plug adapter. However, single-voltage 220V–240V hair dryers, curling irons, and straighteners from Europe/Asia will run at half heat or fail to turn on at 120V—use the free hair dryer provided in virtually every U.S. hotel room.
