Customer Review: Great USB Hub; Works without A/C Power for Me
Summary: 5 Stars
I originally purchased this hub to make it easier to use multiple USB devices with my laptop while using it at my desk at home. My printer, mouse, barcode scanner, and thumb drive are all USB devices, and pulling the laptop out to unplug one and attach another was getting rather old.
It's a smallish hub, but not one so tiny that the ports are so crammed together so as to be nearly useless. At 4 inches wide and less than an inch tall, the hub should easily fit on any desk, and the rubber feet help hold it in place. The ports are widely enough spaced that you shouldn't have a problem attaching cords, thumb drives, or other USB devices.
Since I planned to use it only at my desk anyway, the caveat that an A/C adapter is required didn't bother me--but I've found that the hub works fine without any A/C power at all, and despite the instructions claiming it doesn't draw power from the USB bus, the power LED lights up, and all devices work fine. Without the A/C adapter in use, the hub also runs quite cool and doesn't suffer from the lock-up problems others have mentioned.
If you plan on using mostly powered USB devices--like printers, external hard drives or CD/DVD drives--you should be fine using the hub "unpowered." Using it for a keyboard, mouse, barcode reader, and thumb drive may require the use of the A/C power for reliable operation. And if you're worried about putting too much of a power strain on your laptop's USB bus, connect it via a docking station (as I do) or use the A/C adapter. Still, with that said, many people should be able to use it just fine without having to add another bulky "leech" to their power strips.
Finally, the manual does state that the use of both USB 1 and 2 devices at the same time may cause the hub to drop into USB 1-only mode. I stress "may," as so far the tests I've run with older devices in combination with a USB 2.0 CD burner have worked fine at USB 2 speeds--I assume then the compatibility depends largely on the actual devices used.
