Great Performance For Size

Great portable power bank. The aesthetics of this power back is nice, and it is lightweight. It works how it is supposed to, and it has all the features needed including a power level indicator. I did a couple tests for performance and found this power bank to be fast and reliable. I got this power bank when it was 10-25% charged, and it took 3 hours and 2 minutes to fully charge (almost exactly). I then charged a Samsung Galaxy S6 from dead to 100% while the phone being off. It took the power bank only 1 1/2 hours to charge the phone (almost exactly). For being a small, portable charger, I would say this time for 100% charge is pretty good. After recharging the power bank, I charged a Windows Lumia 650 from dead to 100%. This windows phone turns on automatically when being charged and when it has enough battery power to do so. So, the phone was on and receiving calls and texts while charging. It took the power bank about 1 1/4 - 1 1/2 hours to charge the windows phone completely. The picture I have on here shows the size of the powerbank compared to my hand and my 15.6" laptop.

Overall, a great portable power bank.
