High quality Car USB Charger

I had in the past already find several car USB chargers and needs that this is the highest quality of all. I can quite clearly advise against devices in the design of the Griffin PowerJolt Dual, because their housing with a slight twisting already falling apart and the load capacity is weak.
The EasyAcc loader is the exact opposite. The case with the Aluminum head and the little blue status LED looks quality. The status LED is relatively light, for whom that represents a problem that can either plug the device with LED down or simply stick a piece of tape over it. Also this charger wobbles a bit in the cigarette lighter socket of my Astra G, but what is on the socket itself.
Unfortunately I can not measure it the specified charging current, but my smartphone (HTC One S) is fully charged within one hour, it is about twice as fast as with the original charger.
So far I have no long-term experience, but will resent this u. U..
Finally, once the pros and cons summarized:

Pro:
+ High-quality workmanship
+ High charging current
+ 3 USB Ports

Cons:
- A bit too bright status LED
