No, in 2026, you generally cannot bring a mini blender (like a NutriBullet or Magic Bullet) onto a cruise ship. Almost all major cruise lines—including Carnival, Royal Caribbean, and Disney—classify blenders as "prohibited items" because they contain a heating element or a sharp blade, both of which are considered significant fire and safety hazards. If you bring one in your checked or carry-on luggage, it will likely be confiscated at the security x-ray and held in "lockup" until the end of the cruise. Cruise ships are extremely cautious about any unapproved electrical appliances that could draw high wattage and trip a circuit or start a fire in a cabin. If you need a blender for medical reasons (such as a liquid diet), you must contact the cruise line's "Special Needs" department in advance to request an exemption or to see if the ship's galley can assist with your food preparation. For those just looking for protein shakes, the "pro" tip is to bring a simple shaker bottle with a wire whisk ball, which is perfectly legal and much easier to manage in the compact space of a cruise ship stateroom.
