On the Carnival Luminosa and Carnival Splendor, the staterooms are fitted with a 3-prong 110 volt (North America Grounded) as well as a standard Australian 3-point plug; adaptors providing 220/240 volt 60Hz are available upon request.
On the Carnival Firenze, Carnival Horizon, Carnival Panorama, Carnival Sunrise, Carnival Venezia and Carnival Vista, there is one USB outlet (5 volt, 1000mA) in each stateroom. On the Carnival Celebration, Carnival Jubilee and Mardi Gras, there are multiple USB outlets at the desk and next to the beds.
The outlet in the bathroom can only be used for electric razors.
Power strips, multi plug box outlets/adaptors and extension cords (without surge protectors) are allowed on board when used with proper caution. However, if such devices are determined to pose a hazard, they will be removed and returned the last day of the cruise prior to debark.
