I plugged the HyperJuice box into the DC In. It looks to be charging. The on light is lit. When I press the on button the first light of the battery status bar lights up and blinks. The green light on the HyperJuice box is flashing. But it won't charge more than that left plugged in for hours. I tried again with my computer plugged in as well. When I checked after several hours My MacBook Pro was fully charged up but the HyperJuice battery was dead (on light wouldn't turn on when pressed). I purchased the adapter all set up. I just purchased the battery, and of course did so right before I was traveling and would need it! The battery did work the first day I used it (it was fully charged out of the box). Sure hope it is an easy fix (like I've misunderstood the directions!). Thanks!
