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.
