Can an HDMI Cable Be Used for Charging?

Before I explain How to Charge Laptop With HDMI? Let me clarify whether you can charge your laptop with an HDMI cable. It can be thought of as a modernized version of the traditional three-pin audio, video, and synchrony connections. 

HDMI is the most widely used cable for connecting various devices such as laptops, televisions, projectors, and various other multimedia processing equipment. The majority of us are familiar with the HDMI cable’s basic functionalities.

How to Charge Laptop With HDMI

Let us begin! If you have a device supporting your laptop, you can charge it using an HDMI cable. We’ll walk you through the process in three simple stages, so you never have to worry about running out of battery again!

#1) Check Your Laptop

Before proceeding with the charging, we need to ensure that your laptop can support it! As laptops become slimmer and narrower, the number of ports available decreases.

Examine both sides of your laptop for an HDMI port or a spare port to which you can connect an adaptor cable. Because Macbooks typically lack HDMI connectors, you will require adaptors in this case. 

Other branded laptops typically provide more options, but we still recommend double-checking before proceeding. If your laptop lacks an HDMI port, you’ll need an HDMI adapter cable and a converter to convert HDMI.

Without a connector or converter, you will be unable to charge your laptop using the HDMI cable. Adapters are typically easy to find online or in stores and should not be prohibitively expensive if you require one.

#2) Making Connections 

After locating an adapter and HDMI cable, it’s time to charge your laptop. Connect the HDMI cable to a TV that supports HDMI. Connect another end of the cable to your HDMI port.

Verify that all of your connections are secure and that all ports are operational. The last thing you want is to experience heartbreak when your laptop fails to charge.

Before connecting the connection to your laptop, verify that the ports are available and that the connection will work. Those with laptops equipped with an HDMI port are in for a breeze, as they won’t need to mess with adapters.

If you don’t have one, you’ll need a USB (or whatever port you have available) to HDMI adapter. Connect the adaptor to your HDMI cable, then to your laptop.

#3) Finish Your Connection and Test

The conclusion is in sight! Connect your HDMI cable and adapter to your laptop. Verify that the connection was successful and that the cable and adapter are seated properly in the port. If necessary, you may need to tweak it to ensure the connection is secure.

If your laptop powers on or the charge indicator illuminate, you can rejoice because it worked. If no change is apparent, we recommend disconnecting the HDMI cable and retrying.

It’s possible that one of your connections was less than ideal. Occasionally, it may take several attempts to succeed, particularly if you work with adapters on both ends of your HDMI cable.

Additionally, verify that your television is operational and that the connection is safe. If all you receive is static, there may be a problem with the power source. Wherever possible, you might attempt to resolve the issue by connecting your HDMI connection to a different TV. 

If your laptop continues to refuse to charge, the issue is most likely with your HDMI port or the laptop itself, and you can run additional checks to narrow down the possible causes.

However, if your laptop is charging, you may leave it charging or continue using it normally! Ensure that you do not disconnect the cable until your laptop is fully charged. While this method will take longer than using a laptop charger, utilizing an HDMI cable will suffice if you are in need.

Other Methods of Charging a Laptop Without Using a Charger

You now know that charging your device via HDMI is not a secure option; what are your alternative options for charging a laptop?

A USB cord will suffice if you do not wish to use an HDMI cable. However, because you are aware that you should utilize HDMI, you may also be curious about the safety of USB.

So, is it possible to charge a laptop via USB? Indeed, YES! If you don’t have your laptop’s charger with you, USB is a rather secure way to charge it. To your knowledge, there are three basic varieties of USB on the market:

  • Type A
  • Type B 
  • Type C

Type A is the largest and most popular on the list. All computers, except tiny notebooks, include USB Type-A connectors. A standard USB connection offers 5V and 500mA charging, making it an excellent option for charging a laptop without using a charger.

With a USB cord, you can quickly charge your laptop. It would be beneficial to have a USB to Type-C converter on hand to accomplish this. Connect one end of the USB to the power supply and the other to the type-C converter. 

Finally, using the Type-C connector, connect the converter to the laptop. However, this technique necessitates the use of a converter.

In-Car Charging

Cars are equipped with USB connections for charging portable gadgets such as smartphones. Additionally, you can utilize these connections to charge your laptop. To attain this, you must guarantee that your vehicle is lit. 

After that, connect the cable’s USB end to the USB pin and the charging end to the laptop. Once completed, you are ready to charge your laptop. However, if your vehicle lacks USB connections for charging, have no fear! You may quickly and affordably install a port anywhere in the car.

External Battery 

If you’re unsure how a battery can charge a laptop, it’s important to understand that the battery in this context refers to a standard power bank. The latest notebooks (laptops) are extremely portable and charge similar to a cell phone. These laptops may be recharged using a power bank. 

The procedure is identical to that of charging a cell phone. All you’ll need is a type-C cable and a portable charger. Connect one end to the power bank and the other to the laptop’s type-c connection to begin charging.

Is Charging Your Laptop Over HDMI a Secure Method?

Notebooks that include specialized adapters provide regulated voltage for charging laptops. HDMI is a top-class option if you want to watch high-definition movies on a large screen or even on a high-end machine. 

Moreover, HDMI adapters provide a high current or voltage, which is not ideal for electrical appliances. However, if you become seriously stranded somewhere, we recommend charging your laptop using an HDMI wire. Otherwise, it is suggested to utilize the laptop’s included charging adapter.
