No this is normal. A regular Blackberry charger outputs 700 mAh of current. The Playbook charger is 1800 mAh, so I think it will take forever to charge with the regular charger.
To confirm what Alex338 said - Actually, in the Playbook manual, it lists 'approved' chargers for the Playbook, and my Torch charger is NOT one of them. The Playbook charger is different from the regular phone chargers. (It's also fatter...)
I posted this elsewhere but it may help here also. I found a charger/data cable solution called CSQUID for my blackberry a few months back that also fast-charges my playbook from the PC USB port. It had a mini-USB and micro-USB connectors and so worked for all my devices - it transfers data for my backup harddrive cable and USB DVD cable!
Here are some of the key measurements
- blackberry charge time from PC 1 hour and 10 mins
- playbook charge time is about 3 hours which is same as the wall adapter
- transfer data at USB 2.0 speeds
- charges even when PC is asleep which is convenient
The one negative on it is that the cable is not as flexible as some of the other cables but then that may be to handle the higher current and the quality is TOP NOTCH - unlike some of the cheap made in china stuff that I have seen!
Just did a seach for CSQUID on AMAZON and it is still on there..(I paid $20 for it but the new price is $25...not that big a deal)
