Voltage in Mexico, 110 or 220?

I’m going on a trip to Baha, California(Rocky Point) with friends next month. I want to bring my laptop with external speakers so I can listen to my MP3’s and I’d like to know if the wall outlets are at 110v or 220v. If it’s like Europe, at 220v, I would fry my laptop so I want to be sure about this before I go.
Thanks
