Can you plug PoE into Laptop?

Yes. You can plug the PoE into your laptop. Previous Ethernet standards didn’t support laptops, but the latest PoE standard, PoE++, can support up to 95 watts.

Since the laptop’s maximum power is around 50 watts, you can use the PoE power to charge your computer.

So, there are many aspects to know before plugging in your PoE.

4 Facts to know before plugging PoE into your laptop

You must know many factors before plugging the PoE power into your computer. I have discussed factual information about this.

PoE standard you are using.

There are four fundamental PoE standards upon which PoE relies. These four standards are as follows:

• PoE 802.3af Type 1 provides 15.4 watts.
• PoE+ 802.3at Type 2 facilitates 30 watts
• PoE++ 802.3bt Type 3 enables 60 watts
• PoE++ 802.3bt Type 4 stimulates 95 watts

So, a high-power device like a laptop falls under 50 watts or more. That means if you use the first two standards of PoE, it will not support your computer. So, you need to change the power and use the upgraded principle of PoE, such as PoE++ type 3.

Your laptop is PoE-compatible.

There are two cases. Some laptops are PoE compatible, while some are not. Do you know what PoE compatibility means? The device can be effectively plugged into the PoE and use the PoE technology without interruption. Moreover, standard PoE only supports PoE-compatible devices. In the case of non-PoE devices, you might not get the power.

Therefore, you must ensure your laptop is PoE-compatible.

Ethernet Port you need

Each PoE standard has different Ethernet compatibility. For example, PoE type 1 works with Cat3, while Type 3 does not.

Since your goal is to power the laptop, you need the PoE++ technology. In that case, Cat5 or Cat6 Ethernet port is an essential requirement. So, you have to implement the Cat5 or higher Ethernet category ports.

You have a PoE switch.

To power the devices, you need power supply equipment. That is a PoE switch you need to have in your network. Always check this out, buy the switch, and follow the given process to connect your laptop to the PoE network.

PoE switches conclude layer two and layer 3. You can use any of them, depending on your network requirements.

3 Steps to empower Laptop with PoE technology

If you have completed the above requirements and factors, the next task is to link your laptop with your PoE. Here are three fundamental steps:

• Step 1: Take up your Ethernet port of Cat5 or higher version. Each port has an RJ45 connector at both ends.
• Step 2: Connect one end of the Ethernet port with the PoE switch.
• Step 3: Link the second end of the Ethernet port with the laptop.

That’s the most specific setting in the enterprise’s networks to accomplish the control of PoE.
