Sorry Lew, you have no clue (outch, I just couldn't resist, apologies). I believe you honestly try to help out here, so props for that.
Understand that direct battery voltage isn't used for pretty much anything in a mobile device. It's all stepped to the appropriate levels. Also, you wrongfully make an assumption that a sensor would run all by itself until the battery charge is depleted. Long story short, the battery bankshot isn't going to work, like, at all. So that was a strikeout... Just to be clear: The unit of power (that's what I am interested in) is VA, the unit of current is A (sayeth the trusty documentation), which is incorrect. Sigh. On a sidenote. Not suggesting Lew you did - is this what we're getting when folks listen to the likes of Peter Thiel? Stay in school kids please and get an education.
