One of the most problematic elements of chargers like this is that the 
connector that connects to the cell phone is non-standard and the 
charging voltage and current are unknown. This makes it a bit of a 
challenge to home brew something to replace it.

I'm seeing an increasing number of chargers and/or power supplies like 
this, shipped with everything from cell phones to UHF/VHF mast-mounted 
preamps!  Have not yet tested them for RF trash, but it's on my to do list.
