re: Watch Charging Caddy.

I like my iPhone.  Very rugged.  They don't like getting dropped in the river or Loo.

I get their lowest cost model.  Mine don't need charging stations, sure they won't let me get away without a charging dock.  

Found on my last AARP 8 ways to find your car. One way uses your iPhone.  Yes AARP marks me as retired.

Duck nice build and well documented.
