Delivered is a small black box. This black box is again in a clear plastic blister pack. From outer impression the battery bank is completely suitable as a gift (just in technical articles already experienced the worst packaging).
In addition to the battery were in my package 2 identical USB cable. On the one hand one USB port, on the other side in each case, a micro-USB connection. A multilingual manual is also included. The German manual is translated well easy to understand and with few errors. There are in addition to the manual a couple of images and the functions are explained sufficiently. Very nice and convenient small soft transport bag is which can be opened with a drawstring and close. So the battery bank is well protected on the go.
On battery there are 4 small blue lights. When charging the battery, these indicate the progress, and the remaining energy. One can then judge good, because a light is, for example, that less than 25% power remain. With 2 lights there are at least 25-50%. With 3 Lights of energy level is between 50-75% and at 4 lights at 75-100% lies.
The on / off switch is easy to reach on the top. Front there are 2 USB ports and a micro port intervening again ansich for charging the battery bank.
To start the unit, the on / off switch is held for about 3 seconds. Find Class I because then the battery bank will go not turn in a bag by a random Berühung equal to its own.
For the first charge the battery about 11 hours went by. I have to load the battery pack any power plug with USB port used (A power cord is namely not supplied). It also works with an iPhone power cord. While RavPower battery bank depends on the network, it does not get hot.
The RavPower 10400 battery bank we invite several unerschiedliche devices. We use it for our Samsung Galaxy S4, for iPad, for NoName devices such as MP3 players, etc. It is possible to charge 2 devices at the same time with the battery pack. For Apple devices such as the iPad, just configure it to load the original cable. Works just fine. I can not say exactly whether the device with the battery bank charged less rapidly than directly to the mains plug. As a rule, we have anyway hang only one device off because rarely 2 units are empty at the same time. A full battery bank is sufficient absolutely to repeatedly fully charge a Samsung Galaxy S4. For us, this is more like sufficient.
The RavPower battery bank is on the way a super practical companion, we do not want to miss. For emergencies, there is a great thing to load its devices without outlet.
Unlike other reviews, I have to mention that the USB connectors are fine with me. Nothing wobbles and I find the quality of plug absolutely fine. I feel this way, very high-quality equipment in its black high-gloss finish. From cheap goods therefore one can not speak here. But if I still like to attract attention to the time, I will report here. I invite still high a customer photo to 10400mAh version.
We are very satisfied and recommend the RavPower battery bank 10400mAh you. Very great practical device.
