Any mini usb charger will work that is yes. However there are the odd times that if your blackberry is fully dead, any usb charger will not cut it to power on the phone you would need the exact charger to power it up. As there is a very tiny current difference. Otherwise if your phone is on any usb charger will charge the phone.
I have noticed, BB charging with an USB charger will work fine may take a little bit longer. But using a BB charger on a motorola device is a no go.....
I just realized same thing. My son was using my krazr charger for his 8130 and is having problems keeping signal/radio off/battery low etc. I checked the output voltage of the krazr/motorola charger, and it's 5volts dc. The krazr battery is 3.6 volts, which makes sense for charging. So how are you going to fully charge a 7.2 or 7.4 volt battery with only a 5 volt charger? Maybe the razr is a higher output voltage? Does anyone know the actual output voltage of a genuine 8130 wall charger? Possibly the car charger is different than the wall charger voltages?
I use the Car Charger for my old Razor for my Berry and it works great but as for home chargers I would use the Berry charger. Messing with what is set for 110 power and crossing things with chargers could over time prove to harm the phone.
