Product details:

1. In my mobile phone, mobile power supply, the charge such as digital products, access to the electricity meter, you can see the current working voltage and current, the flow of electricity, year/month/day / / min (calendar).
Insert the use of a standard connection picture here
2. The battery capacity test:
When the battery after it finished completely, recharging, access to the electricity meter, switch and the new data record group: after full of charge of statistics, is the capacity of the battery.
3. The discharge capacity of mobile power supply:
When use mobile charging power supply to other products, access to the electricity meter, switch and the new data record group: discharge end, the power of statistical values. Is the discharge capacity.
Note that put up at a time, can discharge for many times, as long as you don't switch the new data record group. Until the mobile power supply, completely unable to discharge of electricity of statistics is the discharge capacity of the mobile power supply.
4. The efficiency of mobile power calculation:
Completely discharge power of mobile power supply, and the ratio of full charge capacity is the practical work of the mobile power supply efficiency. High efficiency of good quality.
Formula: fully discharge present full charge amount = working efficiency
5. The battery life of statistics:
The service life of rechargeable battery is completely discharge cycles and fully charged. The more, the better the quality.
With the increase of use, capacity will gradually decrease. The smaller the capacity attenuation, the better the quality.
Per charge switch when the new data record group, compare each time power value, reduce the numerical value is smaller, the better the quality.
6. Different charger, mobile power supply quality comparison
Under the condition of the same current, the closer it gets to the 5 v output voltage, the better the quality.
7. Independent power counts, the continuous power, 800 groups of data storage date (including time)
Enter the query condition, can use query historical data: year/month / / by/through the power value. The biggest save 800 groups of data
8 flow pressure protection
When the charging voltage is too high, or the current is too large, the system will automatically power off, stop charging, so as to avoid the battery explosion and human life risk.
