Can I charge my laptop continuously

When working on a laptop, users do not always unplug it when the device is fully charged. Many people are used to working without monitoring the battery level.

It is very convenient to keep your laptop connected to a power source at all times. OBOZREVATEL looked into whether continuous charging harms the system.

Experts say that this will not affect the performance of the laptop. When the battery is fully charged, the power supply process automatically stops. The charging process will not proceed if you see the message "battery fully charged" in the laptop settings. As soon as the charge starts to drop, the power will resume.

That is, the battery will not work worse if you do not unplug the laptop. The battery "wears out" over time, regardless of whether you unplugged the device after it was fully charged or not.

However, there are a few important aspects you should be aware of that can ruin your laptop.

High-quality charging

If you use a low-quality charger, continuous charging can damage your notebook. This includes batteries of unknown origin. Only use original chargers that match your laptop model.

Changes in voltage

Sudden power surges can have a negative impact on your laptop. Experts recommend installing a voltage regulator. This will help when the laptop is constantly connected to the mains.


Do not place your laptop in direct sunlight or in a very hot place. To avoid overheating, you should also pay attention to ventilation. Nothing should obstruct the normal flow of air. If your laptop overheats during operation, you can buy a cooler.

Of course, in the event of a power outage, it is better to keep your laptop constantly charged.
