Laptops, under normal conditions, use universal pins for charging. If the universal pin cable stops working, there aren’t many ways that you can easily charge up your laptop, right? So, are you out of all available options?

Well, not really!

Using an HDMI cable to your laptop is both an easy and efficient alternative charging method. It consumes electricity from a large power source (LCD or LED TV) that supports HDMI and USB-C. However, while this is a decent alternative, it is not the most ideal way to charge your laptop.

Now that you have got an outlook on the matter, it’s high time that we delved deeper into how to charge a laptop with HDMI. So, what are you waiting for? Just scroll down and keep reading!

Is It Possible To Charge A Laptop With HDMI?

If your standard laptop charging cable malfunctions, then charging with the HDMI is a decent alternative. In a nutshell, if your laptop charger does not work, you can opt to use an HDMI cable for charging.

How To Charge Laptop With HDMI

However, do note that it isn’t safe to keep charging your laptop using HDMI. This is because HDMIs can only provide a small amount of voltage. Furthermore, HDMI cables may not provide the ideal wattage for a safe laptop charge.

Since this voltage rating cannot meet the requirements of the laptop, it will charge the laptop incredibly slowly. Slow charge means that the laptop will take a long time to be fully charged.

Furthermore, elongated periods of charging can cause damage to the battery of the laptop in the long run.

How To Charge Laptop With HDMI (Explained)!!

Charging your laptop with an HDMI is not rocket science at all. Just consider following the below steps to charge your laptop via HDMI conveniently:

Method 1: Charging With HDMI Cable

Step 1: Checking Laptop

The first step is more of a preparatory step where you will be ensuring that the laptop can support an HDMI cable. As we go for smaller and thinner laptops, we might not get any HDMI ports. This is because thinner laptops do not have the necessary space to have HDMI ports.

Macbooks, too, don’t have an HDMI cable. In these cases, you might need to use an adapter that will allow you to connect the laptop to the HDMI and convert the pin accordingly.

Move on to the next step once you have secured an HDMI cable that can be connected to the laptop and the adapter if required.

Step 2: Make the Connections

Once you have all the required cables and adapters in hand, it is time that we establish a connection.

To start with, take the HDMI cable and connect it to the port of your TV. Make sure the TV that you are connecting to supports HDMI. Connect the other end of the HDMI to the connector or adapter as required.

Double-check to ensure that the cables are in the right port.

Furthermore, ensure that the ports themselves are working, or else you might end up with a tad bit of disappointment.

Connect the other end of the HDMI or adapter to the laptop and start the connection between the two devices. If the devices ask you to allow them to identify, accept it.

Step 3: Finish the connection

Once you have established the connection, it is now time to test whether the laptop is charging successfully or not. You might need to make some adjustments to ensure that the connection is safe and sound.

Switch your laptop on and check on the charging icon on the bottom right side of the laptop. If the icon is flashing or showing the charging status- you do not need to carry on the rest of the step.

Step 4: Double Check the Connection

In case the charging icon doesn’t show, check on your TV. If you notice that the signal from your TV is showing indications of static, there is a high chance that something is wrong with the power source of your house.

Other factors that could cause this issue include faulty wires in the adapter or HDMI cable. Note to self, even if the cable appears perfect from the outside, faulty internal wires might be causing this broken connection.

Take countermeasures according to the problem that you are facing. You could move on to a different TV with a different power source or replace the cables with a new one.

In extreme cases, none of them works, so there is probably no problem with your cables or power source. The fault lies in your device’s battery. In that case, take the laptop to get it checked and repaired.

Method 2: Charging With HDMI Cable and USB Type-C

Charging With HDMI Cable and USB Type-C

Step 1: Check for Type-C

First off, check out whether your laptop has a USB Type-C port. While you are at it, make sure to find the most ideal power source that you can connect your laptop with. In our case, we are going to be using a TV just like the previous entry.

While you are at it, make any necessary precautions that might be required for certain situations like adapters and extra connectors.

Step 2: Make the Connection

Connect the HDMI cable to the TV port and the other end of the HDMI cable to the USB Type-C port. Once the connections are secured, connect the other end of the USB to your laptop.

Check whether the laptop is charging securely or not. If not, change the power source or replace the cables. Additionally, make sure the battery of the charger itself is working properly.

Frequently Asked Questions (FAQs)

Is charging with HDMI safe?

Charging with HDMI once or twice is relatively safe. However, if you are going to charge for an extended period of time, this could damage the battery’s shelf life in the long run.

So, avoid charging with HDMI cables as much as you can. This is an alternative, not a solution.

Do laptops heat up too much if you charge them with HDMI?

No, HDMI is not supposed to cause your laptop to heat up. Besides, it only uses a very small amount of voltage for the data or energy transfer. Therefore, for HDMI cables, to cause the laptop to overheat is impossible.


Well, then that is all that you need to know about how to charge a laptop with HDMI. A last piece of advice: practice caution whenever HDMIs are involved with charging your laptop. Additionally, never use a cable that is showing signs of wear and tear. You will only thank us later on!
