Mains supply in Aruba: 120 V, 60 Hz, sockets of Types A and B. The grid in Aruba delivers 120 V. Dual-voltage gear copes; single-voltage 230 V devices do not. The grid runs at 60 Hz. Chargers do not care; mains-synchronised clocks and simple motors do.
Handy for multi-stop trips: Haiti, Guatemala, Barbados and Bermuda use the same plug types. Watch out when moving on: Dominica, Greenland and Guadeloupe use a completely different system. 24 of the 31 destinations in North and Central America share the plug types of Aruba.

Mixed supply: Type A without earth, Type B with earth. Which one is in your room only shows on arrival.
120 V is the catch here, not the plug – bring dual-voltage gear. The 60 Hz supply matters for motors and mains clocks, not for chargers. Check your own device →
The records list Types A and B; the grid supplies 120 V at 60 Hz.
What voltage does Aruba use?
Aruba supplies 120 V. Dual-voltage chargers are fine; 230 V-only appliances need a converter.
An adapter changes the plug shape only, not voltage or frequency. Aruba 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.
