So, using the handy little tool you referenced, I scrolled down to see how much of those contributions were from individuals associated with Honda, versus contributions from the Corporation. We'll, the total from Honda, since 1990, was $324k. The total that wasn't from individuals, from the Honda corporation, was...$0. Meanwhile, if you want to find a year where that's applicable to Toyota, you will have to go back to 2012, the furthest back that the history (easily) allows you to go on that site. And their total from corporate and individuals comes in at $8.9M.
My embarrassment knows no bounds.
Mine is always in sleep mode, but I always have it plugged in with the charge limit at 80%. It may not be ideal, but it's always ready. If I'm going to away from home for a few hours, it's still fine. If I was traveling like the OP, I'd turn it off.
