Why would charging a laptop through a Usb Hubs burn the motherboard?

Why would charging a laptop through a USB HUBS burn the motherboard?

There are two main reasons:

1. Short circuit

When we directly plug the USB C Hubs into the laptop, the PCB board inside the dock is directly connected to the laptop motherboard. Therefore, when we charge the laptop through the Usb C Multiport Hub, the entire internal circuit is connected. If the internal circuit design of the dock is not reasonable (such as welding, welding, etc.), short circuit may cause the motherboard to be burned out.

2. Instantaneous high pressure

Now the Usb Hub With Hdmi Port is basically support PD fast charge, some PD fast charge power can reach 80W, or even 100W, when using PD fast charge, if the input voltage is not stable, or the expansion dock internal design is not reasonable (such as the lack of isolation cover), it may be due to the instantaneous voltage is too high and lead to the laptop motherboard is directly breakdown.

Since Usb Hub can cause laptop motherboards to burn out, how can you avoid this happening?

How to avoid the expansion Usb Hub to burn the laptop motherboard?

1. Try not to charge through Usb Hubs.

Now that we know that only when we charge the laptop through the Usb Hubs can the laptop motherboard be burned out, so as long as we try to avoid charging the laptop through the Usb Hubs can reduce the chance of the motherboard being burned out.

But what happens when you have to charge your laptop through the Usb Hubs?

2. Choose a quality dock

Since there is no way to avoid charging through Usb Hubs, we should make great efforts in selecting docking stations and try to choose brands with reliable quality and reliable reputation. For example, YJ brand Usb Hubsis of stable and reliable quality.
