Tegra NOTE supports a variety of USB devices, including game controllers, keyboards, mouse, ethernet adapters as a host and connection to PCs for file transfer as a media device. While other USB power adapters 'might' work, we encourage you to use the adapter that came with your Tegra NOTE, as it both optimizes how quickly your device can charge and ensures that no damage can be done by over-charging. Using other USB adapters is known to cause problems with the touchscreen on Tegra NOTE.
