In this article, we will delve into the details of HDMI power delivery, the power requirements of Roku sticks, and the feasibility of using HDMI to power these devices.
Understanding HDMI Power Delivery
HDMI (High-Definition Multimedia Interface) is a digital video interface standard that connects devices such as TVs, projectors, and audio equipment. While HDMI is primarily used for transmitting audio and video signals, it also has the capability to deliver power to connected devices. This power delivery mechanism is known as HDMI Power Delivery or HDMI PD.
HDMI PD allows a device to draw power from the HDMI port, eliminating the need for a separate power source. However, the amount of power that can be delivered through HDMI is limited. The HDMI 1.4 specification, which is widely used in modern devices, can deliver up to 50 milliamperes (mA) of current at 5 volts. This translates to a maximum power delivery of 0.25 watts.
HDMI Power Delivery Modes
There are two primary modes of HDMI power delivery:
- Bus-powered mode: In this mode, the device draws power directly from the HDMI port. The power is supplied by the HDMI source device, such as a TV or projector.
- Self-powered mode: In this mode, the device has its own power source, such as a battery or an external power adapter. The HDMI port is only used for data transmission.
Roku Stick Power Requirements
Roku sticks are compact streaming devices that require a relatively small amount of power to operate. The power requirements of Roku sticks vary depending on the model and usage patterns. However, most Roku sticks require around 0.5-1.5 watts of power to function.
The Roku Streaming Stick+, for example, requires 0.6 watts of power when idle and up to 1.2 watts when streaming 4K content. The Roku Ultra, on the other hand, requires 0.8 watts of power when idle and up to 1.5 watts when streaming 4K content.
