The power source for a toy crane machine depends entirely on its type and intended use. For small, home-use toy crane machines designed for children, they are most commonly powered by batteries. These typically require standard AA or AAA batteries, making them portable and safe for indoor play without the hazard of power cords. The battery compartment is usually located on the base of the unit.

However, for larger, commercial-grade claw machines found in arcades, shopping malls, or restaurants, the primary power source is a standard electrical plug. These machines connect directly to a wall outlet because they require a constant and significant amount of electricity to operate their stronger motors, bright LED lights, and electronic control systems throughout long operating hours. Some advanced home models or smaller commercial units might also use a plug-in power adapter.

In summary, the rule of thumb is: simple, portable toy cranes for kids usually run on batteries, while the larger, sturdier crane games you see in public venues always plug into an electrical outlet. Always check the manufacturer's instructions on your specific model for the correct and safe power method.
