Home > Consumer Reviews > ADS USB 2 Port Hub

On the face of it this device looks like a god send for us laptop users. However, beware that all is not how it seems. The device will only allow 100mA of power through each port and this is very limiting. So far my Digital Camera, Scanner or ZIP Drive wont work, as they need more power. The Printer does work, and I imagine a mouse and keyboard would work as well.

Overall I would suggest people are better off buying a more expensive USB hub which can handle the extra power requirements of many USB devices. This device is cheap (which is what attracted it to me), but has only limited functionality. (Which isn'e mentioned in the spec)..

I find this item to be well built and to work perfectly. The price is very reasonable and I would recommend it to anyone as long as they understand the inevitable limitations of any bus-powered hub.

These do not connect to the mains and the only power they have is what the computer provides through its USB port. So items which draw a lot of current will not work when connected to such hubs, but low-power devices work fine.

I am using the hub to connect a mouse and a number keypad to the same USB port on my laptop which works great - no problems at all. And not needing a
power supply is very convenient when used with a mobile computer.
