Over the past few months, one exquisite replacement battery derive from Xiaomi has swept a strong and continuous whirlwind both abroad and domestic– Original XIAOMI 2A Power Bank, which is the one enjoyed more than 8000 units sold within a short time. Apart from ergonomic and sleek outward, an extraordinary internal performance is the key to its success.
Electricity conversion efficiency
Under 1A current test, the zero load voltage of XIAOMI 2A 10400mAh Power Bank performs 5.15V while the average voltage is 5.07V. Besides, the capacity is 6825mAh, power up to 34.63Wh and the average volume is 37.44Wh, hence, a surprisingly high conversion efficiency is up to 92.49%, which places top three best power banks among the market at the moment. During the whole test, the figure of effective voltage is up to 4.35V, the energy it outputted is 34.63Wh, which means it is capable to charge iPhone 5s(5.96Wh) fully four and a half times.
How outperform XIAOMI 10400mAh Power Bank on output performance? One test can explained it thoroughly. Under the circumstance of 2.1A electricity voltage test, it is totally question-less to completed an entire test with superb consistence. On the first half of the test, output voltage is about 4.98V while the rest is in 4.95V, which is slightly dropped but still in the range of USB standard voltage (5% around 5V voltage). So, it is one of the only three power bank which finished output test in 2.1A currently, that’s the reason why it is never too exaggerated to called it masterpiece among batteries.
There is no doubt that Original XIAOMI 10400mAh Power Bank can guarantee fast and stable charging performance for our device, what about the performance of self-charging? Under 1A charging environment, it takes 11hours and 20 minutes to charge it fully. When the charging current is up to 2.1A, it takes 5 hours and 20 minutes. Although we have no object of reference to be compared, however, surely no more than 5 power banks achieved as excellent as XIAOMI Power Bank.
As facts speaks louder than words, now you know the reason why Original XIAOMI 2A Power Bank is much better from outside to inside, do you?
