We bought a HyperJuice 2 for use on trips. It's terrible. It'll charge a 15" rMBP about 10-15% before it's completely dead.

It's not made to charge the laptops. It's made to keep them running. The rmbp will suck any battery dry trying to charge and run at the same time. Keep the rmbp at 100% and plug in the battery and let me know how long it lasts.

It's not designed to charge MacBook Pros, just Airs due to the wattage required. I don't believe that's any difference for the GBattery either.
