Very good USB Power Adapter with Power

The USB power adapter "HNP15 USB" was purchased as a power supply for operating a "Cubieboard 3". Since the package "SunFounder Cubieboard 3 Full Version A20 Cubietruck More Powerful Than Raspberry Pi ARM with 3.5" HDD Addon Package USB to TTL "but a power supply was already included, the HNP15 for charging various other devices (smartphones, tablets, etc.) has been tested ,

The observer immediately notices that the power supply at 5V standard 2.5A (2,500 mA) makes, while most standard power supplies provide only 500-1000 mA to 2,000 mA rarely. When loading a "Lumia 1520" this becomes noticeable at the shortened charging time (depending on the remaining capacity of the loading lasts 2 to 3 hours, the charger takes about 3.5-4 hours). Other mobile phones (Samsung Galaxy SIII, Lumia 920 & 930) and tablets (Nexus 7, Amazon Kindle Fire HD) can be loaded in less time.

When loading the AC adapter is not extremely warm / hot and makes otherwise a very solid impression.

CONCLUSION: Very good USB power supply / charger with plenty of power for fast charging!
