The difference between plugging in and unplugging the laptop power adapter

There is almost no difference between plugging in and unplugging the power adapter when the laptop is turned off. If the power adapter is plugged in all the time, there will be a power drop and it will consume more power than if it is not plugged in. Many laptops have indicator lights on the power switch button. When always plugged in, the light will stay on, indicating that the laptop is plugged in. If it is not plugged in, the light will go off. There is no other difference.

 

However, if the laptop is in working condition and the power adapter is unplugged, the situation is very different. Most laptops automatically go into power saving mode, which affects the brightness of the display and the performance of the computer.

 

Why would anyone recommend "unplugging"?

The advice is good, but it is necessary to find out why it is recommended. The laptop's power adapter converts residential electricity into electricity suitable for laptops, and the biggest fear of such electronic devices is high voltage. In the event of a power failure, thunderstorm, etc., if you keep the plug in, it is easy to burn out the power adapter or components in the laptop, such as the network card, motherboard, graphics card, etc.. Therefore, some people will advise users to unplug the power adapter when not using the computer.

 

In fact, it does not matter if the power adapter of your laptop is unplugged or not. If you are worried that your computer will be damaged due to power outages and lightning storms, you can simply unplug it.

  What capacity do I need? Capacity, expressed in milliamp hours (mAh), is a rough indication of charging capacity.

Mobile power can range from a single charge (3,000mAh) to well over (20,000mAh), with most of the latest smartphones having a battery capacity of about 3,000mAh. a 10,000mAh mobile power should be able to charge your smartphone 3 times, while a 20,000mAh mobile power should be able to charge your smartphone more than 6 times.   How long does it take for a mobile power to charge my device?
