Cool idea and nice execution. Have you considered offering a "dual" tray, but with only one having a charger? Second one could just be a standard storage tray.
I got the single charger and I’m very pleased with it. A couple of years ago when I got my truck, I bought a dual storage tray which was handy for storing small items. Now that I have the single charging pad, I decided to split my dual storage tray in 2, and what you see here is the end result.
