hey,

i purchased a dual USB 5v micro car charger the really small GRIFFIN one that has two USB ports, it works perfect with all my devices ipod, iphone, 8900, 9700 , 9780 but for some reason even with the 5V USB cable from the 9900 box it will not charge ?
Does anyone know the reason for this ?
i really want to keep this charger due to its size is there anything else comparable and comptanible with 9900

Griffin one is nice

I have the same problem. I have two Griffin car chargers and neither of them work with my 9900. It's strange because I'm assuming the power output is the same..

I had to go buy a new car charger unfortunately.

which one did you purchase? those griffin ones were perfect size
and even on google it says they are 9900 compatable :S
no one at futureshop bestbuy really knows why either

same here. I used it to charge everything. Got the 9900 and it didnt work so i just bought a bb car charger for the 9900

I do experience this issue on the 9900. On the 9700 or 9800, it works flawlessly but on the 9900, it doesn't work most of the time!! Why? Can someone explain?

Me too I have the same problem with all my USB Car chargers, even the Griffin PowerJolt that can charge my 10 watts iPad.
PowerJolt Micro for iPad - Ultra-low profile 2.1 amp car charger - Griffin Technology

I also have the same problem with Belkin one:
Belkin Car Micro Charger 1 AMP F8Z446ttP

And I also have another brand named RocketFish...

BUT THEY ALL WORK when a use a flimsy retractable USB cable that I got from another charger....
The retractable usb cable looks like the one from this charger:

I also own the Mophie Juice Pack Powerstation

It's the same issue, I can't charge my BB 9900 with any cables except the retractable cable....

it works fine with a lower amperage charger. . a 1 amp will do.

The same here. It's really annoying. Any solutions so far ? Or any other double USB chargers working with 9900 and iPhone ?


rafiks - spec says 5 volts @ 1 amp

i using Nokia DC-6 Micro-USB Car Charger (DC 5.0V/550mA),

and it's works flawlessly on my bold 9900

It doesn't work with BB9900. You can ask griffin to replace it with this one:
PowerJolt Plus Mobile - Car charger for USB mini/micro devices - Griffin Technology

[Strus]

So this one works with 9900 with no doubt ? Can I plug that not working with BB dual USB charger into this one so I can charge BB + 2 other devices ?

[jly.public]

Will they replace it for free? I only have the unit, no box or receipt.

If you're wondering why these chargers don't work its because of how RIM has set up their charging system over USB.
They took a page from Apple's book and the normally unused datalines for chargers in the USB cable carry a very particular voltage to tell the phone that this is a RIM charger and what type of amperage it offers. I'm not sure what voltages RIM uses but apples uses 2V/2V to signify a 500mAH charger (usb standard) and 2V/2.8V I believe to say its over an amp. These aren't the values of the RIM chargers though as they don't work from my tests.
Found most this out working on a DIY charger project for my 9900.

So ya, most chargers ignore or short the datalines however newer bb phones won't charge until they get the correct voltage signal from them. Which makes a lot of the universal chargers useless for this phone.

Hope that helps.
