Product Description

T3Hub was the first USB hub to pick up the design of the now legendary PowerBook Titanium from Apple, expanding a single USB port on the computer to 3 ports for additional USB devices.T3Hub 2.0 continues the tradition - while remaining as small and as useful and as compatible to the USB 2.0 standard. Of course the new model still works perfectly without a power supply, even when used with power-hungry USB devices like USB floppy drives or USB flash drives. Typically T3Hub will be used when the internal USB connections of the computer no longer satisfy the needs of a growing array of USB peripherals.T3Hub is currently available in the colours White (MacBook / iBook), and Aluminum (MacBook Pro / PowerBook G4 Aluminum).In either setup T3Hub plugs directly into the USB connector on the computer. A short USB extension pigtail is provided to reduce strain on the built-in port.Like all mobile USB hubs T3Hub cannot be connected to another non-powered hub such as the hub that is integrated into every USB keyboard for the Mac. As a result T3Hub is always connected directly to one of the computer's built-in USB ports.USB 2.0 without a power supply - how does that work?Many USB devices receive the power they require to operate from the USB bus. The devices indicate their nominally required power when they are connected to a USB hub or a USB port on the computer.A USB hub without power supply will typically refuse to provide power to any device that requires more than 100mA current. USB floppy, SuperDisk, ZIP drive, some USB flash drives and most USB ISDN adapters fit into this category. Typically, these devices do not function when connected to the USB keyboard, which contains a non-powered USB hub.By contrast, T3Hub will report itself as a self-powered hub, so that it can accept devices that have a nominal power requirement of 500 mA. As nominal power is rarely used in full, it usually is no problem to drive additional devices (mice, keyboards etc.) alongside one power-hungry

Now I know why this item is always out of stock and hard to find. I used for 6 months now and it worked perfectly. My portable hard drive and my protable DVD writer work without relying on external AC. It's the only self-powered USB add-on out there.

I got just what I wanted -- a simple design with no moving parts, designed in a way that doesn't block adjascent USB ports on my notebook. I would rate it 5 stars if they found a way to make it just a bit shorter.
