So just to be clear, what is it exactly about BB chargers that might fry the phone? Are we talking more volts then our phone can handle, the amps, or maybe the pin outs are arranged differently then what standard androids use?
The phone is rated to pull up to 1A. Even if a charger is rated at 2A, the phone will still only draw 1A. So, being rated higher is not an issue.
Blackberry car chargers are typically rated ~750mAh. Obviously this is less than the 1A the TB is able to pull. This is also not a problem. The TB will ingest whatever it can get, without any issues.
The TB will only pull 500mAh from a
USB car charger - regardless of whether the output rating of the charger is rated higher than that or not. Because of the way USB car chargers are wired (internally), the TB will see the USB charger as a USB host. It will assume it is plugged into a computer and will not suck anymore than 500mAh in order to prevent damaging the host. In this case it is working as it should. You could crack that charger open and solder a few pins together to circumvent this, but it's probably not worth the effort.
Car chargers are different. Most (if not all) car chargers that Verizon sells are rated at 750mAh out. If you walk into a Verizon store and ask for a car charger -- for your BB -- they are going to sell you the exact same car charger they would sell you for your TB. The one they sell with the USB port on it? That 750mAh is shared by both the cord and the port if you are using both at the same time.
Here's where people run into problems:
If you're in the car using Nav, with the backlight on, and perhaps doing a voice call, or even streaming media, you could potentially be using power at a rate faster than a USB car charger (500mAh) or the Verizon car charger (750mAh) can feed the battery. Since the TB can pull 1A, I would recommend getting
this one that I've used with my Incredible, EVO, Droid X, Fascinate, and now the TB. Feed the phone with all the power it will take. It will not take more than it can, and this is all handled by circuitry.
As far as voltage goes, the TB battery is rated at 3.7 volts, so you need a voltage that is 4.5 to 5.5 volts to generate enough voltage potential to charge the battery. The TB has a voltage regulator to regulate the voltage to the required charging voltage. That said, if a charger went to far over that number, it could actually fry the regulator.
In my experience, it's not the chargers that Verizon sells that cause issues. It's usually the cheap aftermarket chargers that you buy on eBay or other non reputable manufactures that cause issues. I remember back with the EVO, it actually went nuts if you plugged it into certain chargers.
Historically, every forum has a history of threads where some people report that their BB charger works fine, and other say things like
this. I could post about 55 other threads just like that if you want
With BB chargers specifically, it seems to be about a 50/50 split on whether they work or not.
The next step is finding a quality cable, for the wall charger, they including with the TB. The cable that came with it is too short.
I'm looking at
this one and
this one.
Way more info than you asked for, sorry.
