Small powerful USB charger!

# Delivery:
3 days via Hermes. Packaged in a padded envelope.
The product itself was packaged in a frustration-free, reasonable product carton.

# Processing / Private:
I have received the product yesterday. The processing of the product I find quite dibasic. The USB charger is connected via a 1.5m power cord. The good thing is that the charger does not have to be powered directly from the mains, but there is still a certain extent as an extension and can also at or below eg the coffee table are stored. The unit is held still quite small, so that it is also very well come in the luggage. With 6 USB ports 3x 1A and 2.4A 3x has ample space to load its various devices.

The charging current tested my devices at 2.4A port in:
93% charged iPad Air2 = 1300mA
91% charged iPhone 6 = 960mA
seems pretty neat to me.

The 1A or 2.4A ports are difficult to detect. For this you have to the device Always take high, turn the assignment read. This can be a problem especially in a darkened room lighting or farsightedness. I have seen how in the pictures, painted white dots to mark the 2.4A ports, so that I can recognize the same port.

When connecting the device I can hear a high tone Fiep significantly. This is so loud that even listen to radio in low volume, this sound is still clearly visible and permanently very disturbing. Whether I here present a defective appliance I can not judge. In the reviews here it is now and also criticized.

Heat generation, I could not tell.

This buzzing noise is mainly the reason for my 2 star review. Since this is where you are staying in a room very uncomfortable. However, this may be due to a defect, perhaps here the seller to shed some light. In this case I would adjust my rating accordingly to 5 star.

# Price-Performance
As described above, the only shortcoming is currently the Fiep unpleasant sound. If this man were not given, I would feel the 15.99 as a 9/10.

Conclusion #
For 15,999 you get a powerful USB charger that is small and light, so that it can be used for trips alike as "only" stationary at home. 6 USB charging ports, 3 of which have 2.4A might as well take care of the whole family.
Were it not for this very unpleasant high-frequency buzzing noise, this would be a good alternative to many other USB charging station providers.

# Edit 15:05:15:
The provider has replaced the defective unit promptly and lo and behold, the high-frequency buzzing noise is no longer heard in the exchange device.
Therefore, I can now assign conscientiously 5 star, on the one hand for the product, on the other hand for the very occurring behavior of the provider. Many Thanks!
