If you want to know exactly what your devices are getting, skip this one. charging current is far. I've tested several USB power meters and at a 1 amp load this thing reads 1.3, at a 2 amp load it reads 2.6. The voltage reading above is also wrong, it is 5.25V and never changes. With a single 2 amp load, the output voltage dropped about 5.0V. I doubt it would actually be good to charge multiple devices unless they were all low power.
