I received this unit and immediately I thought, yes, not only will this charge my blackberry, but I can actually charge other devices that use the microUSB port. Of course you can always take the existing battery from try charge unit and replace the dead one in the q10.
Initial impressions are great on use, just be aware that the unit does get warm, so keep that in mind if you're charging your phone in your pocket. Build quality is pretty good, except I can see that for those of you who are not careful, might end up cracking the plastic door or even breaking its hinges.
Overall, I'm going to recommend this to anyone who will be out and about with their phone and require some extra power for their blackberry q10s or other micro USB devices.
