tommy, my last post was deleted by whoever. But it was echoing your post that it can’t matter if the gear is on or off, or the four week charging time would start over every day for any gear not left on indefinitely. But before seeing this written, I had assumed it was charging from something being emitted from the gear or at least some electrical force if attached to a fuse box.
You know I am skeptical, but in a really nonchalant manner, but now I am wondering that if it isn’t charging from the gear, when you say "waiting for the mats to charge up can be frustrating", I honestly wonder what the heck is charging the mat, perhaps the sun’s energy bouncing off the atmosphere or the gravitational pull emanating from the center of the earth, bombardments from gamma rays (really)? I don’t have a huge sense of curiosity, but just honestly wondering about this stuff out loud.
