Very disappointed Leicke

I had bought this battery along with an iPad Air Bluetooth Keyboard from Leicke because there was a discount promotion. The keyboard was due to the abysmal processing immediately returned. The battery made at least outwardly a solid impression, so I keep time.

What still first noticed: The instructions provided had little to do with the product. In the guide promised Package Contents:
- Leicke Portable Power Station
- USB Adapter Cable
- USB charging cable
- Micro-USB adapter
- Mini USB Adapter
- Cell Phone Adapters
- Cases
- Instructions

What really was in the package:
- Leicke Portable Power Station
- USB on iOS 30-pin / iOS Lightning / Mini-USB
- Cases
- Instructions

The 3-in-1 adapter cable works as a charging cable. Do you have to come first but it. Ideal is not because the cable is only 30cm long.

The whole has a bit of customer fraud because although allegedly supplied adapter are not advertised on Amazon (they give you in the end what you see in the photos) is on the Leicke website even some talk that "8 matching adapter for various devices, including "are, therefore, even more than what the manual claimed! You have to Leicke doubt insinuate a lie. Or. I have the impression that there are two different models of Leicke with the same model number (!), and that Leicke since even no longer looks. That would be a lie but simply stupidity. Either way, it's impossible.

. For the device itself I have the battery fully charged and then hung on my iPad Air 2 to see how far the iPad can be charged. In two experiments, the battery has each 40 percentage points to the level of discharge of the iPad added (ie roughly four hours duration). The iPad Air 2 has a battery capacity of 7340 mAh, that you get out of the battery about 2940 mAh, so just a little more than half of the promised 5200 mAh. So here also holds Leicke not what was promised. That one, of course, can not expect the full 5200 mAh is to be implemented exactly in charge current clear, but that's a pretty poor performance.

After my second bad experience I will do in the future to the name "Leicke" a wide berth. I think here of the products billigstmöglichen China production is sold to a German brand name, such as the example in Medion is the case.
