Sockets in Honduras: Types A and B, supplied with 120 V at 60 Hz. At 120 V the supply sits well below the 230 V used across Europe. Power supplies marked “100–240 V” are fine; 230 V-only appliances are not. The grid runs at 60 Hz. Chargers do not care; mains-synchronised clocks and simple motors do.
Handy for multi-stop trips: the Dominican Republic, U.S. Virgin Islands, Antigua and Barbuda and Jamaica use the same plug types. Nearby but different: Saint Lucia, Grenada and Dominica – an adapter for Honduras will not fit there. In North and Central America, 24 of 31 recorded destinations use exactly this combination.
Protective earth
Grounded and ungrounded sockets may occur
Earthed sockets (Type B) and unearthed ones (Type A) exist side by side. For metal-bodied appliances the protective-earth path is what matters.
At 120 V it depends on the rating plate: “100–240 V” is fine, single-voltage gear is not.
An adapter changes the plug shape only, not voltage or frequency. Honduras supplies 120 V at 60 Hz – check the rating plate on your device. How to read a rating plate →
If a socket gets hot, crackles or smells burnt, unplug the device straight away.
