Edel packed power battery's technologically advanced

Whether for leisure, university or professional:
Since there is neither smartphones nor Tablets (in my case: iPhone, iPad, Galaxy Tab S) are unable to launch due to their large and powerful displays, to stand for one day intensive use with only one battery charge, I can currently as latest addition the RAV-Power Bank RP-PB 19 with a capacity of 15.000mAh call my own.

Optics / processing
Even as my acquired about a year ago 6000mAh version of RAV-Power (works on almost daily use by the way still excellent) offers the RP-19 PB by its solid build quality and visually very successful design.
The shell is made of a durable plastic and held in matt (I use the black version) and satin silver finish, is also processed very clean and provided all around with rounded edges. For dimensions and weight read easily under the description on Amazon.

Function / Application
Unlike other reviews, the power bank will automatically activate the charge function, when a consumer is infected by charging cable; ie: it definitely needs this no button is pressed.
If the concerned consumers 100% charged, the Power Bank is automatically switched off.
In addition to the intelligent charging function (iSmart technology) is therefore a "overcharging" prevented.
With the four built-in glowing blue LEDs the residual capacity and the current charge status is displayed.
The Power Bank has two outputs with a charging current of 2.1 (for smartphones perfectly adequate) and 2.4 A (for tablets).
A simultaneous charging of smartphone and tablet is (aside from a slightly longer charge time) without any problems. Likewise, the use of each device with simultaneous charging.
The smartphone I could find no prolonged charging time compared to factory-supplied charger.
The two tablets (Galaxy Tab and iPad Air) is, however, this almost 20% more.
For endurance, I can say the following date:
A full charge of the two tablets and a smartphone (IPhone) with only one battery charge provides up to now is no problem. I think more can you honestly definitely not expect from a 15.000mAh battery.
Should the performance, as the RAV 6000mAh variant even after numerous loading operations remain as constant, I definitely have nothing to complain about.
While the built-in flashlight like for many a be a useful feature, for me personally, however, not relevant.

Equipment
In addition to a convenient carrying bag is supplied with two different lengths of cable (USB to Micro-USB) and a user manual.
The two USB adapters (lt. Description Amazon) Micro USB to Mini-USB and micro-USB to 30-pin Samsung were not in my case, which was not annoying for me because I do not use it anyway.
Instead, a charging plug was, in turn, is not listed in the Amazon description.
I'm assuming that the delivery has been updated and I get the latest version.

Conclusion
Considering the design, processing, power and accessories (including. Charging plug) of at first glance appears somewhat high price of currently just under 33.- Euro should still be reasonably justified.
Therefore, I forgive for this product a clear and unconditional purchase recommendation.
