How To Charge Your Laptop With HDMI

It’s easy to take for granted that you can plug in your laptop and get power from an outlet anytime, anywhere. But what if you can’t access a wall socket or can’t be bothered with carrying around a bulky power adapter? In these scenarios, charging your laptop with an HDMI cable can be a great alternative.

HDMI stands for High-Definition Multimedia Interface, a port that allows you to connect devices such as laptops, TVs, and gaming consoles. If you don’t have your standard power adapter, you can use an HDMI cable to charge your laptop quickly and conveniently. In this blog post, we’ll explain the basics of HDMI cables, how to use them to charge your laptop, and offer tips on using the setup safely. Let’s get started!

What Do You Need To Know About HDMI Cables?

An HDMI cable transfers audio and visual signals between devices such as TVs and laptops. The vast majority of modern laptops come equipped with at least one HDMI port – most often located near other ports like USB and Ethernet. Since many electronic devices support HDTVs or projectors via this port, having one gives you more options when connecting different displays. Unfortunately, not all cables are created equal, so it’s important to ensure that yours is compatible with both devices before attempting any connection. An old or faulty cable doesn’t just reduce the quality of your signal – it could even damage one or both connected devices over time.

Charging Your Laptop With an HDMI Cable

If your laptop has an HDMI port but no USB-C port, you can use an adapter that converts USB-C to HDMI to charge your device through the latter connection. Here’s what you should do:

  1. Plug one end of the HDMI cable into the applicable device’s HDMI-OUT port (this could be a TV or other display).
  2. Insert the other end into the available video input on your laptop. 3. If using a USB-C adapter, plug it into both sockets (one in each device) before connecting them with the appropriate cable(s).
  3. Once connected correctly, turn on both devices, ensuring they both receive power from their designated source (e.g., wall outlet).
  4. You should now see a charging icon in your system tray/display options menu, showing that it is powered through its connection with the applicable device – confirming that everything has gone successfully!
  5. Finally, disconnect all relevant wires/cables after powering down each respective device first; failure to do so could lead to permanent hardware damage over time due to the constant current running through them while unplugged from their designated source(s).

Following these steps will help ensure that you can charge your laptop successfully via an HDMI connection without damaging any hardware-related components!
