Performance Result
Wow!!! Kmashi MP828 power bank has total effective power supply of 13880mAh based USB voltmeter reading. That’s around 70% efficiency. Great job indeed. Based on the mobile devices I have – Nexus 4 (2100mAh), Galaxy S4 (2600mAh), Nexus 7 2013 (3950mAh) and iPad 3 (11,560mAh). It can fully charge Nexus 4 for 6.7 times, Galaxy S4 for 5.4 times, Nexus 7 (2013) for 3.5 times and iPad 3 for 1.2 times. Yes, it is the only power bank in my house that can fully change an iPad, 3 times on smaller tablet and more than 5 times on most of the smartphones out there. A perfect power bank to carry during outing for days where you can’t find any power source. By the way, I noticed that Output1 can supply more than 1A just like Output2 (when only Output1 is used). However, it will reduce to 1A when Output2 is been used.
