Docking Stations for construction sites?

As the title says, I currently have a job landscaping and lately have been doing a lot of work on new houses. I want a docking station that will be able to handle being banged around a bit, and protect my iPhone. Does anybody have any suggestions?

Makita Construction Series radio and fast charger or Bosch Power Box. Both at Home Depot - I prefer the Bosch, you can hook the iPhone up using a cord instead of a dock port and keep the phone protected in an Otter case.
