It's small (nay, tiny!), with only 1 power input (looks like microUSB?), 1 output (mini HDMI perhaps?) and a power button / LED. In demonstrations the execution worked exceptionally well. A pretty sweet gadget for the kit bag, imagine rocking up to a hotel with a bunch of movies on your device, this little baby and plugging into your hotel TV. Sweet!
Prices and availability TBC, apologies for the slightly suspect pictures, I blame the poor lighting.
