Guidelines for charging devices using USB via network cables
If you've noticed, some devices come with an integrated network cable for power supply, such as Wifi cameras, and regular network connections. Others may only use a USB port or a regular power outlet to provide power to the device. But what if around your house, there are network ports at power outlets that you don't know how to take advantage of to charge devices using USB via network cables? It's truly a waste.
However, before diving into the article on powering devices without a USB port, you need to make sure that your network cable supports power delivery.
What is Power over Ethernet (POE) technology?
POE is a symbol you often see on Wifi modems, but not all devices have it. POE stands for Power over Ethernet, a technology that allows the use of electrical power transmitted over Ethernet cables (RJ45 cables) to supply power to electronic devices such as Wifi cameras.
How to power without using USB port
All you need is a converter, available at any electronics store for a few hundred thousand dong. It has one input port - an Ethernet port, and two output ports. One main port connects to the Modem or another Ethernet port built into the wall that supports POE. The other port is the converter that helps us switch to the USB port.
Step 1: Plug the Ethernet cable end of the converter into the Modem or into the power outlet with an integrated RJ45 Ethernet port, as shown below. This will be the place we use to supply power.
The end result will look like the image below, where we still have one end to plug in Ethernet and a port to convert to USB, serving to charge devices using USB via the network cable.
Step 2: Insert the ethernet cable into the remaining port if you need to connect to devices such as Wifi cameras or devices using the RJ45 standard.
Step 3: The other end can be plugged into a common USB port converter to power the device through the USB port.
Step 4: For the final step, you can use any peripheral device or simply a phone charger to supply power to the device.
So now you can get power without using the USB port directly. Additionally, charging devices using USB via this network cable method will help you make the most of everything in your home.
Above is a guide on charging devices using USB via the network cable. Although not every home has RJ45 ports embedded in the walls, you can easily find them in hotels and modern housing complexes. If your home has them, make sure to use them in the most sensible way.
Speaking of Ethernet cables, they have many uses and can be adapted for various purposes. For example, using telephone wires as network cables. Despite the differences in the number of wires, you can completely use telephone wires as network cables if you have a bit of knowledge about the types of network cables available today.
