BlackBerry Micro USB Extra Battery Charger (D-Series)

This is a Blackberry product that I am using with the D-X1 for my Blackberry Storm 2. The only piece that ships with this product is the charger itself. You have to use the Micro-USB charger (the transformer/wire) to power this charger. You can also use the car charger (but the instructions state that you can't use the computer USB wire for a charge).The materials suggest that there is a Y-Cable splitter to allow simultaneous charging of the phone and the extra battery, but I haven't been able to find that part anywhere yet.If you want to always have a fresh battery available, I highly recommend this product.
This works great, especially when travelling. I always have an extra battery charged during the day and use this to charge the depleted battery at night.
