As I previously did not know this kind of "portable power", the whole unit is of course now very new to me! And I think it's great!
Since I am not really familiar with cables, I first had to read the manual to see which cable is because now what thought. With the cable, I can charge the device via the PC or I put the USB plug into a power adapter. This will not be included and if I'm honest, I had just found still very great, so I do not have to constantly solve a power adapter from a different cable. For me, this plug into sockets that are not always so easy to achieve.
So I will therefore always charge the device only on the PC, which in turn is also not a problem because there I invite other devices (for example, my Nike Fuelband) on.
The second cable supplied is intended that the device can connect to a mobile phone on the go just to charge it on the go. And I've now tested once directly after my battery indicated about 20%. I had plugged in the USB connector of the cable in the device and at the other end there are three more connectors. One fits into my iPhone, the other in my iPad2 and then is there still a third connector, for which I (think I) currently have no use.
I can charge my iPhone and iPad at the same time and even use the phone on. However, the instructions say that the life of the device may decrease thereby. So I'm going to handle this in an emergency.
The great thing is that I now so even my cell phone can easily download it to your handbag while driving. Or when I am sitting in the beer garden (exactly is happening to me recently that I could no longer charge) or whenever I would like.
I find this idea so wonderful and also looks the part (I have it in white) also very chic made. If my iPhone (also white), beside it, makes it really been what forth. Okay, I'm maybe a little "girl". I just like it when technical stuff is also chic :-)
All in all I think the idea behind this device and the handling superb and hope that I will long enjoy it!
