The Powerbank sits between the Q1 and the power brick to charge both the Q1 and the Powerbank. It has the same PUSH button lighting system to indicate battery charge. There is a small LED on the right,where the power cord plugs in, to indicate charging status. The output power cable to the Q1 on the left is not removable. Our scale here at work says is weighs 1.2 lbs. The Powerbank is about half the size of the Q1. This is actually very similar, but much smaller, to an IBM battery slice I looked at as option for the Q1. FYI, none of the 8 or 9 IBM tips that come with the product fit the Q1 and the IBM 6 hour battery was 3lbs. Of course, that's 6 hours for a laptop!
The thin, multi-language manual doesn't indicate a charge time for the PowerBank. It does say that when plugged in, the internal battery charges first, then the PowerBank. Mine is showing green for fully charged but the battery charge meter won't light. It's supposed to glow orange when charging. I'll guess we'll wait and see. Photos are below.
