2A at the microUSB cable

I originally wanted to buy the power bank from RAIKKO. The also has 6000mA / h and an integrated microUSB cable is additionally also still the same the USB cable to charge the Power Bank laid off. Actually very good. BUT: Only 1A charging current at the microUSB cable. Nee people that did not work.
Next candidate was the EasyAcc iChoc 5000mAh. Has a lot of reviews and therefore first interesting. But Nope, again only at 1A microUSB cable.
Thereupon I searched further and came across the Intenso S6000. This provides the USB port 2.1A and the microUSB proud 2A. Unfortunately, this is the charging cable for recharging not integrated the Power Bank. Since the Power Bank is not loaded on the go, that's good to get over.
Upon receipt, I also tested the same. My Nexus 5 will be loaded in 70 minutes from 15% to 100%. While this corresponds to less than 2A, but this is probably the Nexus 5. A 2A power supply fails more quickly.
After three-time charging (a total of about 6000mA battery arrived in the phone) is the Power Bank completely empty. So the specified 6000mAh fit very well.
Meanwhile, I have 2 pieces of these devices. Where I take a device while traveling and one used in the car as an "intermediate buffer" for a mobile phone lying there permanently.

Pro:
+++ 2A charge current on microUSB (main selling point)
++ Processing / design appears high
++ Price / performance ratio
+ 2.1A charging current to the USB port (to the other)

Neutral:
o No charger here, but you should also have at least the device to be charged already.
but o charging cable not integrated, is attached.

Cons:
- Nothing so far

Conclusion:
Strong buy recommendation!
