How to choose a power bank? Shenzhen mobile power manufacturer teaches you
First: test. Testing refers to testing by yourself. To see the actual charging effect, some readers may ask, I neither have the necessary equipment nor professional knowledge, what should I use for testing? Of course, the test here does not require you to use professional equipment to test. For ordinary consumers, this requirement is also somewhat unrealistic.
Usually, since it is known as a mobile power supply, there is no doubt about it when charging a mobile phone under normal circumstances, so don't just rely on this. Here are some tips for you. Generally speaking, when the battery is low (less than 10%) or the phone is turned off because of no power, charging is more difficult. The same is true for mobile power supplies. The power of mobile power supplies is low (less than 30%). If a mobile phone or digital device is to be supplied with a stable and constant current, higher requirements are placed on its control circuit.
Therefore, if the situation permits, you may wish to use a mobile power bank with less power to charge your mobile phone that is almost out of power or has been turned off due to no power to see if it can work normally, so that you can roughly check the circuit design of a mobile power bank. .
The mobile power manufacturer tells you that there is a short circuit in the mobile power supply, please turn off the power switch first:
1. When using the mobile power supply, if a short circuit occurs, please turn off the power switch before sending the mobile power supply to the factory for repair; do not disassemble or use the damaged mobile power supply by yourself.
2. If the mobile power supply is not used for a long time, please perform charging and discharging at regular intervals to maintain its normal performance. It is best to discharge and charge the mobile power supply once a month, so as to ensure that the internal batteries remain in the best condition and effectively extend their service life.
3. Anti-potent chemicals. Not only should the mobile power supply be kept away from water, but also remember not to use harsh chemicals, cleaning agents or strong detergents to clean the mobile power supply. To remove the stains on the external appearance of the mobile power supply, wipe it with cotton dipped in a small amount of absolute alcohol.
4. Store the mobile power supply in a place that is difficult for children to reach to avoid accidents.
