So I've pretty much decided I'm gonna get the 1500mAh battery for every day use in my Inc., however that will leave me with an extra 1300mAh. Is there a way to charge a spare Inc. battery without it being in the phone? Secondly, when I go on long trips, it would be nice to use the Inc. for media (music, games, etc.). As stated earlier, taking the stock battery along nearly doubles my play time, but can you buy something like a power brick that you can connect to via the charger? Like a 10,000mAh or something? My current solution to this is use my laptop, which is convenient when it's along for the ride anyway, but I don't want to lug a laptop around purely for an "extended battery". Thanks!
