Hi ty,

Here you go -

Frommer's Planning a Trip / Fast Facts / Aruba / Electricity:
"Like the United States and Canada, Aruba uses 110 volts AC (60
cycles). No transformer or adapter is needed, so feel free to bring
your electrical gadgets from home."

Aruba Hotel Reservations - Frequently Asked Questions: Electricity:
"The electrical voltage is 110 A.C. (60 cycles), and the outlets are
the same as in the US & Canada. No adaptors are required for visitors
from these countries."

About Aruba: Electricity:
"The electrical current in Aruba is 110 volts, 60 cycles,
corresponding to that of the USA. For European guests we have adaptors
available at the front desk. These adaptors will allow you to plug in
your 220V appliances and can transfer the output to 220V, if there's
no way to switch your appliance to use 110V."
