When it comes to powering a toy crane machine, the answer depends on the type and size of the toy. Small, home-use toy crane machines designed for children typically operate on batteries. These are portable and safe for kids to use, often requiring standard AA or AAA batteries. The battery compartment is usually located on the bottom or back of the unit. This allows for cord-free play anywhere.

On the other hand, larger, more elaborate toy crane machines that mimic arcade-style claw games often require a plug to connect to a standard wall outlet. These models usually have a power adapter that converts AC power to the lower DC voltage needed by the machine's motors and lights. They offer more consistent power for brighter lights and stronger motor movement but limit placement near an outlet.

Some advanced models might even offer both options for flexibility. Always check the toy's manual or specifications to confirm the correct power source. Using the wrong type can damage the machine. For battery-operated models, always use fresh batteries for optimal performance, and for plug-in models, ensure the power adapter is specifically designed for that toy to ensure safety.
