Functional charger for the car, but the lamp to light when driving at night

I have tested this charger because the plastic case of my previous simple adapter is broken. Compared to that single adapter, it is very convenient that you can charge two devices at the same time as Amazon loader. So I can simultaneously operate the navigation and listening to music from an MP3 player. Both at the same time worked very well without any disturbing phenomena. I also had the impression that my MP3 player was charged much more quickly than on a laptop or PC. The operation is absolutely intuitive: Unpack charger, plug in the power socket, plug the USB cable into the sockets and already is loaded. The 'Frustration-Free Packaging' (in the product description so Needless) was very good: a cardboard box with no foil, plastic or cable ties which enabled a really easy removal of the iPhone and can migrate directly to recycling.

A few minor points there yet: in comparison with similar devices is that Amazon charger quite large (my previous sat more like a flat cap on the power socket). I can not imagine that the size of the double jack (as compared to a single socket) comes to me. In addition, a switch on the charger would have been nice, so you can be stuck there too, and not have to pull out. There are both jacks together even a lamp that has shone the whole time while driving - probably because the Navi drew power all the time. It noticed that the LED light is extremely bright, which during the day is not noticeable, but significantly interfere with night driving.

Here again all positive and negative values ​​at a glance:

+ 2 devices simultaneously
+ Fast loading
+ No 'side effects'
+ Easy handling
+ Environmentally friendly packaging

- No switch
- Lamp to light for night driving
- Only one lamp for two doses
- Charger comparatively large

Overall, I am satisfied with this charger but because it is functional and practical.
