With this one there's nothing wrong! I'm not equipped to measure the actual power to USB ports. Nevertheless I confirm that 2 telephones (1 gala samsung s4 and wiko cink Peax) can be loaded simultaneously. Of course it will be slower than a wall outlet, but the performance is honorable.
The blue LED is also less powerful than the other model that's good because it does not louis and does not attract the eye. It is visible when you turn your gaze to the charger certainly, but it does not bother you!
Charger tested on 3 different cars with no problems whatsoever.
In short: great product! It remains to know its price because at the time I am writing this review Amazon has no more in stock and as I had in test without buying it I can not say I managed to find the correct price .. .
