As odd as it might sound, the PlayBook charger that comes with it is the standard charger for the PB, but it's a rapid charger for your new Bold there is another charger that connects to the other oval connection on the PB with the 3 little pins which acts as the rapid charger for the PB. When I'm at work, I take the PB charger with me in case I need a quick boost of power for my Bold 9930. I have the rapid charger for the PB and highly recommend it.
You will also need to ensure you are using a BlackBerry PlayBook tablet-compatible charger, such as the charger that’s included in the box at purchase. If you own a BlackBerry� smartphone, the charger that you use for it is not compatible with your BlackBerry PlayBook tablet. The BlackBerry PlayBook tablet charger, however, is capable of charging both a BlackBerry PlayBook tablet and a BlackBerry smartphone.
I've asked a couple times in the blog post why they say a standard BlackBerry charger isn't compatible with the PlayBook, but they either haven't responded or didn't answer the question.
I have chargers for my phone all over the place, and don't feel that I need to carry and/or buy ones just to charge the PlayBook. Of course it charges the PlayBook slower, but I don't care as long as I don't need to carry extra chargers with me.
