1.5 to 3 hours.
Under normal circumstances, as long as 500 charge and discharge charging treasure can be considered, after all, from the price or the use of time to consider this kind of mobile power is suitable for ordinary consumers.
The nominal capacity of the charging treasure is only the sum of the energy of the battery cell, a battery cell is 3300mAh, then the energy of the three batteries is 9900mAh, close to 10000mAh.
When this nominal energy is output to mobile phones and other electronic devices, it will lose and lose part of the actual output energy\/total energy of the battery = conversion rate.
Note on the use of charging treasure: It is unavoidable under the sun and rain. It is best to put the charging treasure in a dry, mild environment, if the liquid is very easy to appear line corrosion, high temperature can shorten the life of the electronic original, so that the plastic aging. There is also to avoid use in cold outdoors and low temperatures.
The operating temperature of lithium batteries is basically 0-55 degrees. Too low will make the battery work very unstable and discharge is not sufficient. The general lithium-ion battery operating temperature is 0-35 degrees, the use of charging bank fast charging, try to avoid the temperature is too high, too low to use, the temperature is too low discharge is not sufficient, the temperature is too high can shorten its service life.
