From March to August of 2018, the Guangdong Provincial Consumer Council directed the Maoming City Consumers Committee to conduct a mobile power comparison test. The staff randomly purchased 20 mobile power samples from various retail malls and counters, with nominal capacity from 6000 mA to 20,000. mAh, prices range from 136 yuan to 175 yuan.
The Consumer Council commissions a third-party testing agency to address two indicators that affect performance.Rated Capacity with Conversion efficiency Test comparison.
The rated capacity test results show that 12 of the 20 mobile power samples have measured discharge capacity that meets or exceeds nominal capacity Among them, Hailutong J120, Taipower, Yubo, Huawei and other samples also performed well, and the measured capacity exceeded the rated capacity of the product.
However, the actual discharge capacity of 8 samples is obviously inconsistent with the nominal rated capacity, and the discrepancy rate is as high as 40%., Haiyun P108, PRODA, TZY, Kimberley and other four samples have serious discrepancies, the 'measured capacity / rated capacity' ratio are less than 70%, of which Kimberley measured capacity is only 20.5% of the nominal rated capacity.
Conversion efficiency test results show that all 20 samples meet the standard requirements The conversion efficiency can reach more than 85%. Among them, Romans, Taipower, Huawei, glory, 555, Haiyun samples perform better, and the conversion efficiency is more than 90%.
