USB Devices and Battery Power

You can use USB devices, such as joysticks and keyboards, that get power from the USB connection instead of a separate power adapter with your iBook G4. However, these types of USB devices can cause your iBook G4 battery to become depleted faster. If you are using the device for an extended period, it is a good idea to connect the iBook G4 power adapter.

Using Multiple USB Devices at the Same Time

You can purchase a USB hub to connect multiple USB devices to your computer. The USB hub connects to an open USB port on your computer and provides additional USB ports (usually four or seven). Hi-Speed hubs can support USB 2.0 Hi-Speed devices as well as USB 1.1 compatible devices. USB 1.1 hubs don’t allow Hi-Speed USB devices to operate at their maximum data speed. Most USB hubs have a power adapter and should be plugged into an outlet.
