One of the nice things about the BlackBerry PlayBook is that it uses the industry standard MicroUSB charging and data port. While this is all nice and dandy I am sure all BlackBerry PlayBook owners have noticed that the charger for the BlackBerry PlayBook is not exactly the same… Nikolaus pointed it out to us first by showing that when he tried using a regular BlackBerry smartphone charger on the PlayBook it took forever to charge and barely filled up the half used battery in 6+ hours. He then used the PlayBook charger on his 9650 and noticed that the new pulsating charging icon in OS 6.0 builds was pulsating faster than usual.
So this made me want to dig into this a bit more. I am in no way an electrical engineer but I just decided to look at the chargers at first. A regular BlackBerry smartphone charger states that it can output 5V with 700mA. A PlayBook charger on the other hand is pushing out 1.8A (Amps not Milliamps). I decided to do some more digging on my BlackBerry Torch with the Engineering Screen turned on and found that both of the chargers represent to the OS as capable of pushing 2048 (I am guessing mA) but are limited by the battery to charge at 1250. The only exception was when I charged from a PC usb port which only pushes out 500.
So I thought I would put it out there. Have you noticed any discrepancy between different chargers on your BlackBerry PlayBook? It does not look like the PlayBook charger will charge a BlackBerry smartphone any faster but now I am starting to understand the purpose for the rapid charger accessory. I wonder if it can push out more than 1.8A.
The thing is this means many current BlackBerry accessories like car chargers or phone chargers should not be used if you need a rapid boost on the go. On the other hand I have had no issues with the PlayBook battery with it easily lasting a whole day and more.
