There are number of them out there. Amazon has a pretty good selection. I personally own the Motorola version, model WPS-601-P793. Verizon sells them for $49 dollars if I remember right. It is a 1420 mAh. Does a pretty good job...will recharge your phone about 50%.I would like to know this as well
I have two and got both from Amazon.
Motorola mod. WPS 601-P793 it has
1390 mAh, as stated it only recharges my MAXX about 50%.
Newtrent mod. IMP52D
It's output is 5200 mAh and I get 1-1/2 charges out of it. I really like this unit, I've used it to top off my phone and then my bluetooth head piece. Plus it has a laser and a flash light!

Hey all, I'm shopping for an external battery for my Razr and wanted to know if anyone has any experienced advice or suggestions? Thanks.

I just received this through Amazon yesterday:
Amazon.com: QQ-Tech® Energy Expert: Best External True 2400 mAh Extended Battery Backup Charger Power Bank for Motorola Droid RAZR XT910 (World First & Best) Black: Cell Phones & Accessories It's done a fantastic job thus far, and the added bulk is that of the Razr Maxx's. I've had mine on since 06:00 (currently 15:11) with moderate use, and my Razr still has a full charge... while the external battery is only at 4 out of the 5 regular power spots. dancedroid
