I don't know if they do or not, as I don't have any here I could poke at to test, and there's no quick search that finds any specific info on it. There's probably info out there to tell you, though.
Your best bet to find out *for sure* is to find the communication spec, create a device to let you use this to set whatever voltage you want, then stick taht and a voltmeter on the appropriate type of plug and go to the charger you'd like to use and see what you get for output.
