Can you charge a laptop with HDMI? (How To Charge Guide)

We live in an increasingly digital world and with that comes convenience.

Many of us rely on our laptops to help us get everyday tasks done quickly and efficiently, but what do we do when battery life runs out?

Sure you could use the old-fashioned cords to charge your laptop, but if you’re looking for a more modern solution then look no further – HDMI is here to save the day.

In this guide, we’ll explore how charging a laptop via HDMI can be beneficial, reliable and worry-free.

We’ll also cover potential drawbacks, so read on if you want to know more about whether using an HDMI cable is the ideal way of powering up your device.

Can you really charge a laptop with HDMI?

It may seem surprising but yes, it is possible to charge a laptop with an HDMI cable.

This technology works by taking power from your computer monitor’s USB ports, transferring it via the HDMI cable, and then feeding it into the USB-C port of the laptop as energy.

This allows for more efficient setup, either at a desk or on the go, as you don’t need to worry about having two power cords.

However, not all devices are compatible with this method and caution should be taken before attempting it.

Make sure that your monitor can support fast charging over the USB before using this method to avoid damage to your laptop and monitor.

How To Charge Laptop With HDMI?

Once you’ve made sure that your laptop can be charged using an HDMI cable, follow these steps: 

  • Connect one end of the HDMI cable into the port on your laptop and the other end into a monitor or TV that has its own power source.
  • Power on both devices and ensure that they are connected properly (you should see the display on both screens).
  • Once connected, select “HDMI” as the input source for both devices.
  • Finally, turn off any power saving settings on your laptop so that it continues charging while in use.
  • You will now be able to use both devices at once while also keeping your laptop charged.

Benefits of charging a laptop with HDMI:

One such revolutionary development is the ability to charge a laptop through an HDMI port, with its vast array of benefits paving the way for a seamless, fuss-free user experience. Dive into the key advantages of charging your laptop through HDMI and witness a new level of convenience and efficiency in your digital life.

Reduced Cable Clutter:

One of the most significant benefits of using the HDMI port for charging laptops is the considerable reduction in cable clutter.

These days, as workspaces become more compact, and users demand increased mobility, the need to minimize the number of cables and wires around the area is essential.

By charging through an HDMI port, users can eliminate the need for an additional power cable, resulting in a minimalist, neat, and well-organized workspace.

This is especially appealing to users who have multiple devices and require efficient cable management solutions.

Dual Functionality:

Another advantage of charging laptops through HDMI ports is the port’s dual functionality.

HDMI, or High Definition Multimedia Interface, is primarily known for transmitting high-quality video and audio from one device to another.

Thus, charging a laptop through HDMI means you can simultaneously power your device and transmit video and audio to an external display.

This can be extremely useful for people who use multiple screens or presenters who need to display their work on a larger platform without worrying about finding a separate power source for their laptop.

Universal Compatibility:

The HDMI port is rapidly becoming a standard feature on most digital devices, including laptops, TVs, gaming consoles, and more.

Hence, charging through an HDMI port offers universal compatibility, removing the need for multiple charging adapters and enabling users to use a single cable with a wide range of devices.

Not only does this simplify the setup and overall process, but also reduces the chances of device incompatibility.

Faster Charging Speeds:

Charging your laptop through the HDMI port can sometimes offer faster charging speeds compared to other charging methods.

The HDMI port is designed to handle data transfer at higher bandwidths. Consequently, it can efficiently and quickly transfer energy to your laptop’s battery.

While this may vary depending on the individual device, in certain instances, you might experience more efficient charging with an HDMI cable.


Manufacturers now acknowledge the benefits of charging laptops through an HDMI port and are increasingly incorporating this feature into their latest products.

Therefore, opting for a laptop with an HDMI charging feature can make your investment more future-ready, with a reduced need to upgrade to new hardware as the technology evolves.

This can be especially beneficial for professionals and businesses that require their equipment to be in sync with the latest available technology.

Drawbacks to charging a laptop with HDMI:

While this may seem like a handy solution, it can come with some risks. Let’s explore the drawbacks of charging your laptop with HDMI.

Compatibility Issues

The biggest problem with charging a laptop via HDMI is compatibility.

Not all laptops are compatible with this method, and even if it works initially, there’s no guarantee that it will continue to work over time.

It’s best to check the user manual and website information for your specific model before attempting to charge via HDMI. 

Overheating Risks

Another issue is that using an HDMI connection to charge your laptop can lead to overheating issues.

This is because the device needs more power than the connection can provide, leading the laptop to draw too much power from other sources such as its internal components or battery.

This can cause damage not only to the equipment but also void any warranties you may have on your laptop.   

Incorrect Voltage Supply

Another issue that comes up when charging through an HDMI connection is incorrect voltage supply.

If you are plugging in incorrectly rated voltage into your device, it could cause serious damage and even render it unusable altogether.

That’s why it’s important to double-check that the voltage output matches what your battery requires before plugging in through an HDMI connection.


Lastly, yes it is possible to charge a laptop via HDMI with an active adapter.

Depending on your device type and the specifics of the individual adapter you have access to, this could be a great solution for times when you need extra juice or your traditional outlet isn’t available.

However, it’s important to do your research before making something like this work as compatibility, speed strength of power, and other details all play into how successful this will be.

At the end of the day, if having a fully charged laptop at any moment is important to you then knowing if HDMI power can provide that for you is something worth considering.


Is HDMI port used for charging?

Yes, some laptops are now capable of charging through the HDMI port. However, it’s important to check compatibility first as not all models are compatible with this feature. Additionally, incorrect voltage supply can lead to damage or malfunctioning of your equipment.

Can an HDMI cable charge a laptop?

No, an HDMI cable alone cannot be used to charge a laptop. In order to charge your device through an HDMI port, you’ll need to use an active adapter that can convert the output into the necessary voltage supply.

Is it safe to charge a laptop with HDMI?

Yes, in certain cases charging a laptop via HDMI is safe as long as the voltage supplied by the active adapter is compatible with your device. However, it’s important to check the user manual and website information for your specific model before attempting to charge via HDMI to avoid any potential risks or damage.
