Overall the design of this is really nice I like the compactness and the one amp charging port.
It looks nice and sleek I like the matte black paint and it fits very nicely in your pocket. I also like the .1 Watt led it is nice and bright adding to the already very useful product. I was able to charge all my mobile devices (iPhone 4, iPhone 6, Galaxy s3, Winbook Tablet, and Bluetooth headphones) that use USB easily so I would see no problem with compatibility of any other devices.
There is a power button on the side that when pressed starts charging the device connected to it and is nothing is connected it shows the percentage of charge at 25% per blue led on the front. When you double press the power button it activates the flashlight, pressing and holding activates a sos sequence from the led light.
One downside is that there is only one USB port, but from a 5200 mAh charger I wouldn’t try charging multiple devices at once anyway.
I love the sleek design and it fits nicely into the palm of your hand. This power bank comes with two micro USB cables and a manual.
I was able to quickly charge this and all the devices I used it to charge. I was able to get a complete charge into my phone in less that two hours. It also has two USB ports so you can charge two things at once or charge something at a faster speed on the 2.1 Amp USB. I have used this power bank many times to charge my iPhone it was just able to charge my phone three times.
Overall this power bank is very nicely designed and is very sturdy it has a bit of weight to it and has a nice aluminum body that makes it fingerprint resistant and somewhat scratch proof.
The build quality of this cable is much better than an Apple cable especially with the protective nylon fiber cloth protecting the cord rather than the rubbery feel from an Apple cable. At about 40 inches this cable is about the same length as a standard Apple cable but with a nice design as I was provided an orange one with a black and white pattern. This cable even fits with all my iPhone 5 cases.
Looking at all the features of this cord it is stylish and durable. I did tie a knot in it once to see how it would hold up and it was surprisingly better than a normal apple cable because I have gotten knots in plain apple chargers and they would lose shape, but this cord easily unties and returns to original length.
