Re: How many spare batteries do you have?
 

As much as I liked my Mugen, I hated to death the cheap plastic cover. I got rid of it because I found that I A) didn't use it enough, and B) felt scared to use it for fear of destroying the plastic cover. Now if someone were to make a metal cover for it, I'd get another Mugen in a heartbeat. Well, I would as soon as the need for that much battery life came around again. lol.

Haha how much extra battery life did you have? I'm thinking I might get one for long car rides.

Re: How many spare batteries do you have?
 

Well, the Mugen battery doubles your run time from the stock battery. So 7 hrs of runtime on a stock battery would translate to 14 hrs on the Mugen. I used the thing while I was out in Las Vegas at CES. Watched movies and listened to music almost the entire way out, plus time before the flight, and after, and hardly touched more than a quarter of the battery. Of course, after CES, I found that I didn't use it anymore for the above reasons.

That's why I sold mine off. Now if Mugen starts selling their product with a metal cover, I may consider one again. I say *may*, because the times when I really need the extra battery life, such as on previously mentioned long rides (plane, car, etc), can easily be supplemented by my Tekkeon battery pack. :) Once I'm no longer sitting still and I'm on the move, the battery pack isn't needed anymore.

I have two (cheap ones I picked up online somewhere), and they seem fine, but I have a car charger for car trips.
