How To Charge A Laptop With HDMI?

Laptops are one of the greatest inventions of the century with high portability and long battery life. But charging them can be pretty challenging if you are traveling to places where there is no power point available, or it’s too far away from you, or worst, if your charger stops working. There are multiple ways through which you can charge your laptop, like by using a solar charger. But what if you don’t have access to any of those things. Can you charge a laptop with HDMI? 

If you have a laptop with an HDMI port, using an HDMI cable to charge your device should not be a problem. Thus, if your charger stops working while you are using your device, you can still use the HDMI cable to recharge your device. But how can you charge a laptop with HDMI cable?

There are many people who get confused and don’t know what to do. But don’t worry; you can use this guide to charge your laptop with an HDMI port without breaking a sweat. 

What is HDMI?

The most common way of connecting your computer to an external monitor or TV is through a High-Definition Multimedia Interface or HDMI cable. The cables are small, thin enough to fit into tight spaces quickly, and shielded so that electromagnetic interference doesn’t affect quality. 

There are two types of HDMI connectors: Type A and Type C. Hardware often come with labeled connectors, but if you can’t figure out which one is which, try them both until they fit. When you look at each type of connector head-on, there will be 5 metal ports arranged in an upside-down triangle shape and surrounded by plastic molding. 

Type-A ports have 19 pins, while type C has 25 pins. To determine which port is which, count how many pins there are; type A has two rows, and type C has 3. Remember that A comes before C in alphabetical order if you’re still confused. 

So, if it fits correctly, it should be a Type-A port. You can also use an adapter to connect via HDMI if you don’t have either port available. If all else fails, take your laptop to a professional for help installing it!

However, most laptops these days come with an HDMI port, especially gaming laptops, as it allows you to connect your device to multiple other gaming consoles, including Xbox and PlayStation. It also allows you to connect a laptop with multiple monitors so that you can use multiple screens at the same time through the same device. 

How To Charge A Laptop With HDMI?

Step 1: Power adapters

First off, you’ll need a power adapter for your computer. Your computer will either come with an adapter that plugs into a wall outlet or a USB port on your computer itself. Either way, plug in your adapter and wait for some lights or indicators on your laptop and its power supply unit (PSU) to light up. 

Most of these are pretty easy to understand: green lights are good, red lights mean there’s some problem—it probably won’t run without that little green light lighting up first. When you have plugged in everything correctly, you should see at least two lights turn on. One is usually labeled power or battery and indicates whether your battery is charging or full. 

The other will tell whether your computer is plugged into AC power (via a cord) or running off battery alone. In most cases, both of these lights will turn on when everything is connected correctly. 

Step 2: Get A USB Type-C cords

You can use USB Type-C cords for powering laptops and cell phones. However, most USB C cords do not supply enough voltage and amps to power laptops directly from a USB cord. If you want to charge your laptop using only a USB cord, you need an adapter to plug into your computer’s power jack. 

We recommend purchasing an adapter that will convert 12V DC power into 5V DC power (often called 5V 2A). This means they can quickly provide up to 5 volts at two amps, which is enough electricity to power any computer (even laptops) fully. Most adapters have interchangeable tips so that you can use them in different countries worldwide.

Step 3: Get Converters

To power your laptop from your TV, you’ll need an HDMI male-to-male cable and a DVI female-to-female (or USB female-to-female) adapter for your PC. 

The cables are typically included in any Apple computer or easily purchased online or at most electronics stores. Plug one end of your HDMI cable into your laptop, then plug the other into your television. Plug one end of your DVI/USB adapter into an open port on your computer, then plug it into one of the ports on your television. 

If all goes well, you should see that windows have detected both devices and are working together correctly. Now, plug in a USB mouse/keyboard combo to another port on either device, and you should be able to see them.

Step 4: Charge your Laptop from a TV

Many laptops come with one, and most televisions have at least one port. Just plug your USB power adapter (the power source) into your TV and your laptop. It is just like you can directly plug it into the wall socket! Make sure you remember which end goes where, though. 

The flat end of your USB cord should go into your laptop and not go into any other part of your television. The square-shaped end will go into a wall or television outlet depending on how long you want to run it. 

If you don’t know how much length you need, ask someone who does or takes some measurements before buying anything. Once you’ve got a long enough line, there’s no reason why you shouldn’t be able to make do. You don’t want to buy something that won’t work when you get home because it isn’t long enough.

This way, you will be able to charge a laptop with HDMI cable without a problem. But only do so if you really want to charge your device but don’t have any other option to do so. Otherwise, charging your device with the charging port that it comes with is the best way to charge your device fastly and safely.

How To Charge A Laptop With USB Type-C?

Another way to charge your laptop is by using the USB Type-C cable. However, some laptops come with a Type-C charging port on their own but if your device doesn’t have one here is how you can do it. First, get yourself a plug adapter along with a box-shaped plug present at the end of your phone charger; after that plug, it into an outlet.

Now, just connect one end of the USB cable to your laptop and the other end to the outlet, and your device with start charging. It is a pretty straightforward way and does not take much time. Just make sure you have the right adapter and a working Type-C cable, and you are good to go. 

Can you charge a laptop through the USB port?

Most laptops, tablets, and smartphones these days use lithium-ion batteries. You can charge many of these devices by using USB cables. However, some laptops particularly MacBooks and Windows ultra-books use proprietary power adapters (or chargers). 

Unlike USB ports, which can vary widely in terms of how much power they deliver, these laptops are designed for specific chargers. Because different models have different types of power ports, there’s no one-size-fits-all solution for charging your laptop. 

In general, however, you will find that if you plug any charger into a USB port on your laptop, it will work just fine; it’s only when trying to connect directly from your computer’s proprietary port that things get tricky.

How can I charge my laptop without a charger?

Fortunately, there is more straightforward way to do that. All you need is a mini-USB cable and an iPad charger. To charge your laptop using your iPhone or iPad charger, connect it to an outlet and then use your phone’s charging cable (also known as lightning cable) and connect it to your computer. 

Also, note that you can still use your computer while charging its battery using an iPhone / iPad charger. Therefore, for such a method of assessing work properly, ensure that your PC is plugged into a power source and check whether the AutoPlay dialog box on Windows appears on-screen when you connect the phone/tablet charger.

You can also charge your laptop with a car battery; however, it’s not the most ideal and safe way to do it. Thus, if you don’t have any other options left, then you can use them as your last resort. 

Can I charge my laptop from my monitor?

If you have multiple devices that require USB ports and only one port, consider purchasing an HMDI switcher. This device uses one of your existing computer’s USB ports for power to allow multiple computers or for connecting other devices through a single HMDI cable. 

People mostly use these commonly in conference rooms where several people may want to connect their laptops at once, but only one HMDI input is available. You can also use it in homes or offices where several family members share a TV but have different laptops they wish to use. 

Check your computer manufacturer’s website for information about whether it will work with your specific model.


An HDMI cable can transfer audio and video data, which means you can use it for more than just connecting your TV and computer. By utilizing your computer’s capabilities, you can use an HDMI cable to power a device such as your laptop or iPhone. 

Though it may not work in all instances, using an HDMI cable as a power cord has advantages. One main advantage is that most modern televisions will have multiple HDMI ports available, so you won’t need to disconnect any existing devices; all you need is one for your computer and another for charging your phone or another.
