My Galaxy S5 is within a very short time (about 30-45 minutes felt) of less than 20% to 100% fully charged battery during very heavy apps I have open simultaneously.
I can store my phone on average 6 x back to 100% when I have no apps open simultaneously, 4-5 x if I run power-hungry apps during charging.
The only thing that bothers me a little bit (but not very seriously), that could possibly be about 2 cm narrower the anchor, so that it better fits into a jacket pocket. In the current format that's very scarce in some pockets.
But apart from that I absolutely can not complain and use it daily.
The supplied cables are robust and the cloth bag makes good with me for, that's all protected and remain together.
