Plugged in a Blue LED on the device, not just discreetly, so perhaps not suitable for the nightstand. If a consumer is connected, no power consumption is measurable, can therefore remain permanently in the wall socket.
The USB ports have different currents of up to 2.4 amps 1Ampere (2x 1A, 1.4A 1x, 1x 2.4), even a tablet is so loaded quite quickly.
So far I had loaded simultaneously a tablet, smartphone and an external battery charger. The device operates completely silent, is in this case, however, quite warm (but not heis), but what I think is normal.
Conclusion:
Power reliably what it should go in parallel from various devices and, thereby obviating the part externally a high-quality impression.
For the price a very good product.
