🕐
Frequency differs. The frequency in United Kingdom (50Hz) differs from the United States (60Hz). Be extra careful with motorised devices and items with timers or motors (clocks, shavers, some medical devices).
Many chargers (phones, laptops, cameras) are labelled INPUT: 100–240V, 50/60Hz — those work anywhere and only need a plug adapter, never a converter. Always check the label.
