I haven't used the charging feature, but it's more than adequate for my digital audio production on my MacBook Pro. I've connected a digital audio interface, a MIDI keyboard controller, an external hard drive, and a few other devices, and they all work fine through a single USB port on the MacBook. The device does not heat up and makes no noise. I like the ability to turn off the power on individual outlets. It looks modern, understated and has an organized workspace. Very happy!
