When I unpacked the device, I found it first very robust and "smart" all in white. It had been big but not as big as I thought when ordering! I have 2 Power Banks (for 1 times and 2 times Samsung Galaxy S2 load). I've been very happy but often both I had to take with you when I had my tablet too. Delivered it comes bundled with a USB-miniUSB cable!
Nowadays a smartphone needs to be frequently loaded times, and I still have the problem of mobility problems to. If I have my cell phone on the socket, I'll often times not as fast as I would like Ran! It is also important always to have one contact with the outside world, if I fall down!
Since it's pretty simple: I always have a power supply in the pocket of my walker, so no matter whether at home or on the road to load my phone easily load, on the 2nd jack I can also my tablet or my husband's cell phone at the same load. My girlfriends are also happy when I can make electricity at the pub before a cappuccino available)
I invite the device only about every 3 days (the entire load on the Samsung plug my smartphone lasts about 10 hours so a whole night), and I invite my smartphone then 2-3 days only so. I invite my smartphone from 15-20% remaining charge and it does not take longer than from the socket (2 hrs 40)! My Tablet takes much longer to do with my tablet. The Power Bank than enough for my 8 charges S2!
The 4 small blue LED lights on this device always show how much power does the Power Bank still intus! Only after 2 full charges of my S2 LED goes out. I particularly like also that the device stops charging automatically as soon as the batteries to be charged devices are full! This saves energy yes!
Of course I will always complement gradually this review once I have to report something important! But I am first very satisfied!
Addendum of 04/08/2015
I've gotten a Samsung Galaxy S5 Mini 4 full loads. I invite my phone only on the Power Bank. This is then fully charged at night. If 2 devices can be charged simultaneously, it may happen that the loading takes a little longer. But it's not really noticed.
The Power Bank still sees despite a fall from new. It's really beautiful, chic, stable ... really top quality!
