- Does this hub need to be plugged into the wall?
- Yes. It ships with an AC adapter, and that is what lets it power four devices at full current. It also works as a bus-powered hub, but power-hungry drives may drop out.
- Can I charge a phone from it?
- It can charge over USB-A, but charging is slow compared with a dedicated charger. Treat it as a data hub first.
- Does it support USB 3.0 speeds?
- Yes, the ports are USB 3.0 and fall back to USB 2.0 with older devices. Real-world speed depends on the drive and the host port.
- Will it work with a Mac or a Chromebook?
- Yes, it is driver-free and works with any host that has a USB-A port. Macs with only USB-C need an adapter or a USB-C to USB-A cable.
- What is in the box?
- The hub and its AC power adapter. A USB cable to the computer is part of the unit; check the listing for the exact cable length.
- Can each port be turned off separately?
- Yes, every port has its own switch, so you can cut power to one device while the others keep running.
