Question: BB10 could be the Q10? or just the Z10?
Document: Works just as advertised. Can be used either for the Blackberry Q10 or the Blackberry Z10. Very useful mainly on long trips.
Recharges your battery pretty fast. Very handy and useful product. All Z10 or Q10 users should have this excellent charger.
This is for the Z10, not the Q10. That might have been nice to list in the description. Anyone looking for an opened, but never used Z10 bundle?
The Z10 battery is 1800 mAmps; the Q10 battery is 2100 mAmps. Can't really go wrong either way. Happy charging!
Does it's job but could have been better thought out.
Have yet to figure out what the charging problem is with this Blackberry Q10 system. Batteries aren't particularly good. Made for cradle causes accidental damage to the phone's principle port. This seems to serve better for carrying a fully charged battery to use as an auxiliary source when the main battery depletes.
I loved the idea. Something I could plug in my battery while I used the spare. Something I could even charge my phone and the spare at the same time. But problems occurred while charging. It took way too long to charge both my phone batter in the phone and the spare in this charger. In fact, sometimes it would never fully charge even after a couple days. Sometimes, it only charged the phone but not the spare when both plugged in. Worst was the durability.
It is able to charge my Blackberry Z10 for up to 45% or so. Thought it would do better than this. But still it is ok for this price.
A must have with the z10. I can literally go all day now with my Z10. Absolutely amazing and a must have.
Is very useful. Light and very good support. The Z10 battery covers just 3/4 hours. This charger is very necessary
Answer: The Q10 has a larger battery than the Z10. This battery is specifically for the Z10. The charger will work with either phone but the batteries are not interchangeable. I hope this helps.
