Slow Charging From Laptop: You must have often noticed that when you charge your smartphone by plugging it into a laptop, it charges very slowly. Even if the phone supports fast charging, it charges slower from the laptop socket. Many people believe that this happens due to the phone's large battery, but let us tell you that this is not so. 90% of the people do not have the right information about it.

The design of the laptop is the main reason.

The main job of a laptop is to run software. It is not designed keeping in mind the need to charge other devices.

Laptop's power-sharing is limited

Since the laptop operates on battery, it is made power efficient to give more battery backup. Because of this, the power-sharing capacity of the laptop's USB port is low.

There is no power adapter inside the laptop.

The laptop does not give much power output, because there is no device like a charger inside it. If the laptop starts providing a fast charging facility to all devices, then an adapter will have to be installed inside the laptop, which will increase the size of the battery and by doing this the weight of the laptop will increase a lot.

The safety of the laptop will be in danger.

The circuit board of the laptop has small and low-power circuits, in which there is a low amount of current flow. If the power output of the USB socket of the laptop is increased, then the risk of its damage will increase. High power flow can also cause short-circuits in the laptop.
