upscale, but worth every penny

The harvester combines equal to 2 useful features in one device.
First, he supplied his strong 3000mAh battery buffer using its integrated automatic charging with power from the hub dynamo. And secondly, he can load due to the buffer battery, the smartphone or navigation device with a constant charging current from the buffer battery.
He does this from an average speed of about 15km / h. A Samsung S4 mini (Battery Power: 1900mAh), the harvesters with GPS, Blutooth, Smart Blutooth, GPRS activated. An open music player at full volume and the fitness program "runtastic Bike Pro" fully charge, and additionally supplied its buffer battery.
This speaks very well for ausgetüfelte charging algorithms.
That he does so even in the promised high charging current I notice at the fast charging capability. Fahrenschon 30min wheel allow battery gauge of about 20%. That's top despite the energy that my smartphone while driving wheel due to the many helpers activated consumed.

Because the device is expensive, I do not have it permanently on the bike. I prefer to be able to assemble and disassemble the Harvester easily.
The method I is applying to be seen on the attached photos. In this type of installation the Harvester is firmly seated on the handlebar. Riddled with craters also bike paths and thus many shocks puts the lock off well.
In addition, it allows you constantly as users and the function LED has in mind and is constantly on the functioning of the harvester to date.

The harvester comes with complete accessories.
- Power cable with two crimp connectors and connector for hub dynamo
- Additional crimp connector
- Frame Gummies
- Cable ties for installing the power cable and attach the frame Gummies
- 2x clamps for the Harvester on the frame Gummies

The cable is pre-shrunk clean. I needed no tools. Just plug in and try the supplied cable to Dynamo and Harvester. The USB socket is easily accessible and allows the USB cable fed into place. Even when shaken during the journey to the USB connection does not loosen.

The app "be on bike" I do not use. With the full version "Road Bike Pro" runtastic I am well served.

My Conclusion:
A dream come true for me as recreational cyclists. Because so far my tours were limited to the battery level of your smartphone.
The Harvester I'm making no thoughts spontaneously to get on your bike when it is at 16%. So I skip the current charging at home.
In addition, the buffer battery with its 3000mAh is so great that I dimensioned problems even during long periods (up to 60min) could charge your smartphone on.
Strong buy recommendation!

Addendum 01.07.2015:
The Harvester is still a fixed part of my trips. Warm summer rain and moderate sleet he puts away. It's worth it, depending on the route which is driven, for cycling to use the phone at 100% and to be able to just leave the Harvester just invite.
With an average speed you give the harvester a chance to fully load its 3.000mAh. one can loose his phone 3-4 times can be loaded at the next cycling alongside.
