So, I ended up seeing this at Staples last night...

...and just ordered one from Amazon. I already use the Skosch magnetic mount in the car, so I already have one of their mounting plates in my Priv's case, so that makes it perfect... except for only being 2.1 Amp charging. I wish I could find one that does either 2.4 Amp or QuickCharge 2.0 or 3.0, but beggers can't be choosers. This option was hard enough to find to begin with. Once I've tried it out, I'll post again with my thoughts on it.
