How to Charge Laptop with HDMI: A Quick and Easy Solution
If you want to charge your laptop with HDMI, you might wonder if it is possible and how to do it. HDMI stands for High-Definition Multimedia Interface, a standard for transmitting audio and video signals between devices. HDMI cables are commonly used to connect laptops to TVs, monitors, projectors, and other devices.
But can you use an HDMI cable to charge your laptop? The answer is yes, but not directly. You will need some additional devices and steps to make it work. In this article, we will explain how to charge a laptop with HDMI, what to remember before charging your laptop with HDMI, and some alternative ways to charge your laptop without a charger. Let’s get started!
How To Charge Laptop With HDMI
Before we dive into the details of how to charge a laptop with HDMI, there are some things you need to know and remember. Charging your laptop with HDMI is not risk-free or foolproof, and it can have some drawbacks and limitations. Here are some of the things to remember before charging your laptop with HDMI:
- Check the compatibility of your devices: Not all laptops and HDMI devices are compatible. Some laptops have HDMI input ports, while others have HDMI output ports. Similarly, some HDMI devices have HDMI output ports, while others have HDMI input ports. You must ensure that your laptop and the HDMI device you use have opposite HDMI ports. Otherwise, you will not be able to connect them. For example, if your laptop has an HDMI output port, you must use an HDMI device with an HDMI input port, such as a TV, monitor, or projector.
- Check the power output of your HDMI device: Not all HDMI devices have the same power output. Depending on their specifications and settings, some HDMI devices can provide more power than others. You need to check the power output of your HDMI device and compare it with the power input of your laptop. The power output of your HDMI device should be equal to or higher than the power input of your laptop. Otherwise, you will not be able to charge your laptop with HDMI. For example, if your laptop requires 19V and 3.42A to charge, you must use an HDMI device that can provide at least 19V and 3.42A power.
- Use a high-quality HDMI cable: The quality of your HDMI cable can affect the charging process. You need to use a high-quality HDMI cable that can support the power output of your HDMI device and the power input of your laptop. You also need to ensure your HDMI cable is not damaged or faulty, which can cause short circuits or overheating. A suitable HDMI cable should have gold-plated connectors, thick shielding, and a high-speed rating.
- Monitor the charging process: Charging your laptop with HDMI is costly. It can take a long time to charge your laptop with HDMI, depending on the power output of your HDMI device and the power input of your laptop. You also need to monitor the charging process and check your laptop’s battery status regularly. You should not leave your laptop unattended while charging with HDMI, as this can cause overheating, overcharging, or damage to your laptop or HDMI device. You should also unplug the HDMI cable when your laptop is fully charged or not using it.
Now that you know what to remember before charging your laptop with HDMI let’s see how. There are two methods to charge a laptop with HDMI: charging with HDMI to HDMI cable and charging with HDMI to USB adaptor. We will explain each method in detail below.
Charging with HDMI to HDMI Cable
This is the simplest and most straightforward method to charge a laptop with HDMI. You will need an HDMI to HDMI cable, a laptop with an HDMI input port, and an HDMI device with an HDMI output port. Here are the steps to charge a laptop with HDMI to HDMI cable:
- Step 1: Connect one end of the HDMI to the HDMI cable to the HDMI output port of your HDMI device, such as a TV, monitor, or projector.
- Step 2: Connect the other end of the HDMI to the HDMI cable to the HDMI input port of your laptop.
- Step 3: Turn on your HDMI device and your laptop. You should see the display of your HDMI device on your laptop screen. This means that the HDMI connection is working, and the HDMI signal is being transmitted.
- Step 4: Check the battery status of your laptop. You should see a charging icon or a message indicating your laptop is charging. The HDMI signal is converted into power and delivered to your laptop battery.
- Step 5: Monitor the charging process and check your laptop’s battery status regularly. You should also adjust the settings of your HDMI device and your laptop to optimize the power output and input. For example, you can lower the brightness, volume, and resolution of your HDMI device and your laptop to reduce power consumption and increase the charging speed.
Charging with HDMI to USB Adaptor
This is another method to charge a laptop with HDMI. You will need an HDMI to USB adaptor, an HDMI to HDMI cable, a USB to USB cable, a laptop with an HDMI output port, and an HDMI device with an HDMI input port. Here are the steps to charge a laptop with HDMI to USB adaptor:
- Step 1: Connect one end of the HDMI to the HDMI cable to the HDMI output port of your laptop.
- Step 2: Connect the other end of the HDMI to the HDMI cable to the USB adaptor’s input port.
- Step 3: Connect one end of the USB to the USB cable to the USB output port of the HDMI to the USB adaptor.
- Step 4: Connect the other end of the USB to the USB cable to the USB input port of your laptop.
- Step 5: Turn on your laptop and your HDMI device. You should see the display of your laptop on your HDMI device screen. This means that the HDMI connection is working, and the HDMI signal is being transmitted.
- Step 6: Check the battery status of your laptop. You should see a charging icon or a message indicating your laptop is charging. The HDMI signal is converted into power and delivered to your laptop battery via the USB cable.
- Step 7: Monitor the charging process and check your laptop’s battery status regularly. You should also adjust the settings of your laptop and your HDMI device to optimize the power output and input. For example, you can lower the brightness, volume, and resolution of your laptop and your HDMI device to reduce power consumption and increase the charging speed.
How To Charge Laptop Battery Without Laptop
If you don’t have an HDMI device or an HDMI to USB adaptor, you might wonder how to charge a laptop battery without a laptop. There are other ways to charge your laptop battery without using your laptop or a charger. Here are some of the methods you can try:
- Use a universal power bank: A universal power bank is a portable device that can store and provide power to various devices, including laptops (such as Portable Charger 38800mAh,LCD Display Power Bank). You will need a universal power bank with the same voltage and current as your laptop battery and a compatible connector or adaptor. You can charge your laptop battery to the universal power bank. However, you need to be careful about the power bank’s polarity and capacity, as using the wrong power bank can damage your laptop battery or cause a fire.
- Use a universal power adapter: A universal power adapter is a device that can convert the AC power from a wall outlet to the DC power that your laptop battery needs (Such as Universal All in One Worldwide Travel Adapter Power Converters Wall Charger). You will need a universal power adapter with the same voltage and current as your laptop battery and a compatible connector or adaptor. You can connect your laptop battery to the universal power adapter and plug it into a wall outlet. However, you need to be careful about the power adapter’s polarity and quality, as using the wrong power adapter can damage your laptop battery or cause a short circuit.
- Use a car battery charger: A car battery charger is a device that can charge a car battery using the DC power from a car cigarette lighter socket (such as NOCO GENIUS1, 1A Smart Car Battery Charger). You will need a car battery charger with the same voltage and current as your laptop battery and a compatible connector or adaptor.
