Do you need a voltage converter in Bulgaria?
⚡
Mind the voltage. The standard voltage in Bulgaria (230V) is much higher than in the United States (120V). Without a converter you risk serious damage to your devices.
🕐
Frequency differs. The frequency in Bulgaria (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.
