brilliant mobile charger, no spare battery or battery pack

My desire has been to during my Norway fishing trip, in this spare battery in connection with my Samsung Galaxy S3 Mini, a Seekartenapp by Navionics and a waterproof shell to have a mobile chartplotter at hand brings me from the power source independently for several days to the desired fishing spots ,

To this end, the description of the device at Amazon.com is unfortunately inaccurate, so that this wish could not be fulfilled to 100%.

But now in turn why I positively evaluated the device yet with 5 star:
After ordering and paying I could hold the device after only 3 days in the hands. I was surprised, despite the low price on the high quality of workmanship and the extensive accessories. Unfortunately, I had, like many others before me, find that a USB-capable device is not part of the outlet of the package!

After I bought a USB charger in the next media market, I know now that even the normal phone charger cable from Samsung would have been suitable.

After only 11 days I received from the company ZBT International Trading GmbH a call with the question of how I was satisfied with the RAVPower device? To date, had the device, not even completed a full charge cycle with me, so I after 2 'months can only now give to an objective answer:

Generally one can say that it is the RAVPower 10400mAh Power Bank is a dual USB charger and not as referred to an external battery pack or an external spare battery. As a permanent power source for a device, the Power Bank is not suitable. As a USB charger is for super class!

You do exactly as charger what they should. She invites the mobile phone battery to 100% and then switches itself off. For my desired mobile chartplotter, however, this meant that I had to phone each separate from the Power Bank after charging and have only connected when required again. An activation of the charging process via the button on the Power Bank would have been possible, however, was used by me only once.

Without that I have the RAVPower 10400mAh Power Bank or my phone in Norway connected only once to the power outlet, I'm so come on Angel 9 days 6 hours of continuous use of mobile phones as a chartplotter. For me, an amazing unexpected performance. That is why I was the cable entry and -ausstecken the device ultimately could not care less.

To date I have now completed a total of 6 charging cycles with the RAVPower. The self-charge the device at the network is using the USB charger for about 12 hours, with the Samsung charger cable, it takes a little longer. One should not be discouraged when loading from the fact that after a good six hours still the first charging lamp lights, the other 3 lamps can be reached then the faster.

The Power Bank manages then my 3 month old Samsung Galaxy S3 Mini, at about 10% battery indicator, an average of 6.8 full recharge again before the device must be connected to the outlet itself again.
The charge of the mobile phone carried by no means slower than with the mobile phone's own charging cable.

As the mobile charger RAVPower 10400mAh Power Bank is highly recommended! However, it is not an external spare battery or external battery pack in the true sense of a permanent power supply!
