Service lifespan
Batteries
Usually the standard imported 18650 A product battery, the number of uses is about 500 times, the domestic first-line big card is not bad. But the life of the second-line brand is basically between 300-400 times.
capacity
The larger the capacity of the mobile power source, the longer the total life, because the mobile power capacity is usually larger, and the longer it is used after being fully charged, the longer the life is naturally.
Circuit board
Equivalent to the brain, the mobile power supply with high-quality circuit board is more durable, easy to use, and safer. If it is a mobile power source of inferior circuit board, there are many faults, which may damage the mobile phone and even have the danger of explosion.

Battery capacity impact
Because there are many kinds of mobile power supply on the market, for example, 2200mAh, 3000mAh, 4800mAh, 8000mAh, 18000mAh, etc. Of course, the time required for charging 2200mAh and 18000mAh mobile power under the same conditions is definitely different.
Effect of charging current
Theoretically, the larger the charging current, the shorter the time required to fully charge the mobile power supply. However, the standard charging and discharging current is generally 0.2 C. For example, a mobile power supply of 5000 mAh, the charging current is generally 5000*0.2=1000 mA.
Mobile power charging time = cell capacity / charging current
For example: 5000mAh mobile power, input voltage, current: 5V, 1000mAh, then, the time required to fully charge the mobile power = 5000mAh / 1000mAh = 5 hours. Of course, this is done without calculating any losses, so theoretically the charging time will be a little longer than 5 hours.
How to charge the charging treasure
1. Recognize the functions of each component and each interface of the mobile power supply, and distinguish which interface should be used by your own equipment to prevent damage to the equipment caused by the wrong interface.
2. After selecting the corresponding connector, you can charge it. Of course, these interfaces are just a few of the commonly used ones. If it is convenient, it is best to charge the original data cable.
3, in the charging process is generally carried out automatically, to choose a charging treasure with overcharge protection, in order to prevent damage caused by overcharging.
4, in addition to the larger capacity products need special charger to charge faster, generally use mobile phone charger, of course, can also use computer USB interface (not recommended).
5, some charging treasure will LED lights and other functions, in general use is directly controlled by the power switch, long press 2 seconds, or short press twice to open or close.
Charging treasure charging precautions
New mobile power first charge
When the newly purchased mobile power supply is used for the first time, the power is very low, so the first charge after purchase is best charged and then used.
Use of the plug
When charging the mobile power, try to choose a good socket or plug, and some bad sockets and small capacity of the plug are easy to cause security risks.
Charging time
When charging the mobile power itself, the general time is 2-5 hours. After fully charging, it is best to unplug it from the socket in time. Do not let it be charged for a long time.
Use a matching USB interface
The devices corresponding to various USB data lines are different. In order to use the mobile power supply to power the device normally, please use the matching USB data interface.
Device input voltage
Pay attention to the input voltage range of the device when charging. The universal mobile power supply voltage output range is 5.3+-0.5v. If it is not within the range of the mobile power supply, it is not recommended.
