Experts pointed out that although mobile power brings convenience to life, improper use will bring many risks.

First, pay attention to its output voltage range. When charging a tablet, you need to choose a mobile power supply with 5V/2A output interface, and tablets such as iPad need to be charged when it is turned off, otherwise it may not be fully charged or used for a short time. The output voltage of mobile power supply must be within the range of 5-0.5 V, otherwise some brands of mobile phones may be damaged.

Secondly, it is necessary to charge and discharge the mobile power supply regularly. Long-term storage will lead to over-discharge of the battery cells and decrease in capacity.

In addition, it is necessary to avoid external impact and use it in high temperature or supercooled environment. At the same time, do not use the equipment while charging to avoid danger.
