2. Follow the shutdown sequence after the end of the use: first close the page, then shut down, and finally remove the plug. Some car owners have convenient maps. When they are used up, they simply pull the plug and never turn it off. This is a troublesome thing, but it takes a long time to damage the electronic components.

3. It is best to charge the machine for about 10 hours before the machine is used, so that the battery storage capacity can be maximized.
