Zack Morris, we found your new cell phone variant. I keep a charger in the car, and a usb at work to help combat the poor battery life of my MotoDroid
Holy crap.....that picture reminds me of that superbowl commercial where the guy says his cell comes with security system too and when the other guy asks to see it, he whips the phone at his head knocking him out. LOL, with this brick stuck to the back of the droid it would definitely be classified as a lethal weapon.
That's not to bad of an option if one really needs an extended battery. I think most people would be better off just realizing that smart-phones require a different charging mindset (i.e. if you're stationary it should be on the charger, home, car, office). Just my $.02
You are right to be wary. There is much bullcrap. Be wary of me too, because I may be wrong. Make up your own mind after you evaluate all the evidence and the logic. - Mark Rippetoe
Although the size of the battery is outside the envelope of the original phone design, this battery fills a need for some and I applaud the finding. At this stage I have not had any issue with battery life so remain with the OEM one but for others like the original poster this may be a great solution to enable the Droid to be used as they need it.
