Abstract: A shareable battery pack for a portable ultrasonic apparatus, a trolley, a power supply system, and a portable ultrasonic system. The trolley can be connected to the portable ultrasonic apparatus and/or the shareable battery pack to supply power so as to extend operation time. Alternatively, the trolley is used to support the portable ultrasonic apparatus and/or the shareable battery pack without supplying power to extend operation time. In an embodiment, the shareable battery pack can be removed from the trolley, and then be fixedly connected to the portable ultrasonic apparatus to form an integral unit and serve as an external battery for the portable ultrasonic apparatus. Such design enables the portable ultrasonic apparatus to have extended operation time without relying on the trolley and requires only one shareable battery pack in special situations, thereby enhancing convenience of use.
