Price / performance hit

Finally, a battery charger, which delivers what it promises. The power supply loads my Google Nexus 5 takes approximately one hour to complete. The original power supply of LG consumption over 4 hours!
The PSU is present from my phone as such (battery status: AC) and not as a USB port on a PC, making the phone would only 500mA to approve.
The power supply is only warm, not hot. Noise I could so far not notice, but not yet charged in a quiet area where I would have to stand out.
On my Raspberry Pi I have not yet tested the part, then comes soon also times.
Only that the power supply a tightly integrated cable, and a USB port as has most other chargers, bothers me a little. So the cable length you can namely not to rig, as they are needed. This is probably due to that the cable thus very compact and flexible fails. Ideal therefore for transport. I reckon the power supply so not to negatively.

Summary:

+ Super fast loading
+ Does not get hot
+ No noise
+ Processed sound

o cable permanently installed

- Nothing

All in all, strong buy recommendation. Get me down probably another two or three of them.
