These are 2 x 1.0-amp USB chargers, not a 2.0-amp charger. These still work well with my iPad (though slower charging) along with phones and other tablets. Very satisfied with purchase. They do have a "powered" indicator light on them that shines though the white case.
We use this little charger to plug the Chromcast device into our projector that we have mounted on the ceiling in our makeshift theater room. It works great!
It works, although I notice that the USB slot is a bit hard when plugging in but other than that, it charges my devices pretty fast.
I bought this and used it for a few weeks. Does charge two devices through USB. But the charge time is some what longer than the single plug factory chargers. Not much a problem if you are not in a hurry.
