Can HDMI Cables Charge Devices?
HDMI cables are primarily designed for transmitting audio and video signals between devices, such as from a Blu-ray player to a television. While HDMI cables do have the capability to carry a small amount of power, this is typically only enough to support the operation of small devices like active HDMI splitters or repeaters. The amount of power that can be carried over an HDMI cable is limited by the HDMI specification, which dictates that the maximum power consumption of a device connected via HDMI should not exceed 50 milliamps.
In practice, this means that HDMI cables are not capable of charging devices that require a significant amount of power, such as smartphones or laptops. These devices require a much higher current to charge, typically in the range of 1-2 amps, which is far beyond the capabilities of an HDMI cable. Therefore, while HDMI cables can support the operation of small devices, they are not a viable means of charging larger devices that require more power. For these devices, a separate power source, such as a USB charger or wall adapter, is still necessary.
What is the MHL Standard and How Does it Relate to HDMI Charging?
The MHL (Mobile High-Definition Link) standard is a technology that allows mobile devices, such as smartphones and tablets, to be connected to HDTVs and other displays via an HDMI cable. MHL is designed to enable the transmission of high-definition video and audio from a mobile device to a display, while also allowing the device to be charged at the same time. The MHL standard uses a special type of HDMI cable that is capable of carrying a higher amount of power than a standard HDMI cable, typically up to 900 milliamps.
However, it’s worth noting that not all HDMI cables or devices support the MHL standard, and even among those that do, the charging capabilities may vary. Some MHL-enabled devices may only be able to charge at a slow rate, while others may be able to charge at a faster rate. Additionally, the MHL standard has largely been superseded by other technologies, such as USB-C, which offer more flexible and higher-power charging capabilities. As a result, while MHL is still supported by some devices, it is no longer a widely used or recommended means of charging devices via HDMI.
Can I Use an HDMI Cable to Charge My Smartphone?

If you need to charge your smartphone, it’s best to use a dedicated charger or charging cable that is specifically designed for the device. These chargers and cables are designed to provide the correct amount of power to the device, and are typically much safer and more reliable than attempting to charge via an HDMI cable. Additionally, many smartphones now support wireless charging or fast charging via USB-C, which can be a more convenient and efficient way to charge your device.
Are There Any Devices That Can Be Charged via HDMI?
While HDMI cables are not capable of charging larger devices like smartphones or laptops, there are some smaller devices that can be powered or charged via HDMI. These devices typically require a very small amount of power to operate, and can often be powered directly from the HDMI port of a TV or other device. Examples of devices that may be able to be powered or charged via HDMI include small streaming devices, such as Google Chromecast or Amazon Fire TV, as well as some types of HDMI splitters or repeaters.
However, it’s worth noting that even among devices that can be powered via HDMI, the power requirements may vary. Some devices may require a separate power source, even if they can also be powered via HDMI, while others may be able to operate solely from the power provided by the HDMI port. Additionally, the availability of power over HDMI may depend on the specific TV or device being used, as well as the type of HDMI cable and any adapters or splitters that are in use.
How Much Power Can an HDMI Cable Carry?
The amount of power that an HDMI cable can carry is limited by the HDMI specification, which dictates that the maximum power consumption of a device connected via HDMI should not exceed 50 milliamps. This is a relatively small amount of power, and is typically only enough to support the operation of small devices like active HDMI splitters or repeaters. In practice, the actual amount of power that can be carried by an HDMI cable may be even lower, depending on the quality of the cable and the devices being used.
It’s worth noting that some newer versions of the HDMI specification, such as HDMI 2.1, do provide for higher power delivery over the HDMI cable. However, these higher power levels are typically only available on newer devices that specifically support the newer HDMI standard, and may not be compatible with older devices or cables. Additionally, even with the higher power delivery capabilities of newer HDMI versions, the amount of power that can be carried over an HDMI cable is still relatively limited compared to other types of cables, such as USB-C.
Can I Damage My Device by Attempting to Charge it via HDMI?
Yes, attempting to charge a device via HDMI can potentially damage the device or the cable. If the device requires more power than the HDMI cable can provide, it may attempt to draw more current than the cable is designed to handle, which can cause the cable to overheat or become damaged. Additionally, if the device is not designed to be charged via HDMI, attempting to do so may cause damage to the device’s internal components or circuitry.
To avoid damaging your device or cable, it’s best to use a dedicated charger or charging cable that is specifically designed for the device. These chargers and cables are designed to provide the correct amount of power to the device, and are typically much safer and more reliable than attempting to charge via an HDMI cable. If you’re unsure about the charging capabilities of your device or cable, it’s always best to consult the manufacturer’s documentation or contact their support team for guidance.
