Precautions for purchasing and using mobile power

　　Today, the editor will talk about some issues that primary users of mobile power supplies should pay attention to when purchasing, as well as some common sense issues that should be paid attention to when actually using mobile power supplies:

　　Things to note when purchasing a mobile power bank:

　　1. Set the 3C products to be connected: such as mobile phones, tablet computers, netbooks, laptop batteries, etc.

　　2. According to the 3C products to be connected: determine the necessary output voltage, current, and capacity (power).

　　3. According to the 3C product to be connected: decide whether to use it for single function (single output port) or multi-function (dual output ports).

　　4. According to the 3C product to be connected: determine the required additional functions.

　　5. Determine the appearance of the mobile power supply: light, thin, short and small.

　　Precautions for using mobile power

　　When using mobile power products, you need to pay attention to several issues.

　　a. To charge your IPAD or Samsung tablet, you must choose a mobile power supply with a 5v/2A output. Using a mobile power supply with an output below 2A will result in insufficient charging and a short usage time after charging. The device must be charged in the off state, otherwise it may not be able to charge.

　　b. The output voltage of the mobile power supply must be within the range of 5~0.5V, otherwise it cannot charge certain brands of mobile phones;

　　c. The transfer connector must be matched. The principle of using mobile power products is to charge digital devices through a USB cable. One end of the cable with a USB interface is connected to the mobile power product, and the other end is connected to the digital device. Therefore, the interface at the other end must be consistent with the interface of the digital device, otherwise charging will not be possible. In addition, the internal resistance of the USB cable cannot be too large. Exceeding the normal standard will cause the charging time to be too long or even charging failure.

　　d. The mobile power supply should be placed in a dry environment. Rain, moisture and various liquids or water will corrode electronic components and circuits.

　　e. Mobile power supplies cannot be stored in high temperature places. High temperature will shorten the life of electronic devices, damage batteries and age certain plastics.

　　f. Do not throw or hit the power bank in a rough manner. Rough use may damage the internal circuit board and precision machinery.

　　g. Avoid using it outdoors or at low temperatures. The operating temperature of a general lithium battery is 0-55 degrees Celsius. Too low a temperature will cause the battery to work unstably and discharge incompletely.

　　h. Mobile power supplies generally have standard USB ports. When charging a mobile power supply, please choose a reliable charger. A USB charger of poor quality and without overcurrent protection may cause irreversible damage to the mobile power supply during the charging process.
