1. Actual capacity detection refers to the detection of the battery capacity of each mobile power supply. The significance of this test is to see if the nominal capacity of each mobile power supply matches the actual capacity. If the actual capacity of the battery is lower than the nominal capacity, then this mobile power supply is considered as a virtual capacity. We will use battery sub containers for this test, where each mobile power supply battery is fully discharged and charged to test its actual capacity. 2. Internal resistance test: The internal resistance test of the battery cell mainly tests the resistance value of each mobile power supply battery cell. For battery cells, the smaller the internal resistance, the better the battery's power supply capacity. The larger the internal resistance, the poorer the power supply capacity. This test actually tests the quality of the battery, and currently there is no standardized standard. Under normal circumstances, the internal resistance of the battery generally does not approach or exceed 100m Ω. We also use battery sub containers for this test. 3. The significance of testing the actual conversion efficiency of a mobile power supply is the same as that of a PC power supply, that is, the ratio between the effective energy output to the device end and the actual output energy of the mobile power supply. The higher the conversion efficiency, the better the quality of the mobile power supply. We believe that a qualified mobile power supply should have a conversion efficiency of at least 80% or more. Due to the fact that the conversion efficiency of mobile power sources mainly relies on PCB circuit boards, we will use a load tester to test the circuit boards of each mobile power source
