Streaming content using a data streaming device having limited power is described. A data streaming device receives streaming content from a network and provides the streaming content for display on a content display device. Data streaming device includes power supplies that receive power from the content display device. The power supplies use the power to operate components of data streaming device that process the streaming content. A measuring module measures the power provided to the data streaming device. When the power is insufficient, a controller generates an indication that there is insufficient power to operate the components of the data streaming device. The controller may also modify functionality of the components to operate using available power or disable a component of the data streaming device.
