Ever since upgrading to my Samsung Galaxy Note 8 (Quick wireless charging and waterproof) I'd been searching for a weather proof wireless charging option for the phone on the Valk. I even wrote to RAM Mounts asking if they had any solutions, and was told that no, they don't.
So I started thinking.
Scary, I know.
That's when I found this device on Amazon:
https://www.amazon.com/gp/product/B078MGY2S1/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1High speed wireless charging, ultra thin, and weather proof. Even comes with a sticky pad to mount it.
Got one, mounted it to my existing RAM mount on the Valk, plugged it into my existing high-speed charging USB outlet, and wham, my Valkyrie navigation and music (And other things) is now weather proof, wireless (I don't have to futz with the cable to plug it in every time I get on or off the bike!)
Took it for a test ride today and so far, it works awesome!

(I'd post a pic of the phone mounted on the mount with the wireless charging puck in place, but it's hard to take a pic of the phone that you use to take the pics, and I'm too lazy to get my real camera out of the safe to take the pic.

)
Hope this might help someone, I'm happy I found this combination at least!
