No info on that. I've been charging a phone from a computer USB and it started 
at 0.47 amp and
a little under 5 V. Now phone shows fully charged and 5.12 V and 0.08 Amp.

I suspect it will do 4-6V and 0-1 Amp. Maybe 2 if lucky.

    Browsing at Princess Auto in Kanata I found a USB dongle that displays 
voltage and current
    passing through to 2 charging / download ports. $4.99. Never seen something 
like this before.
    Thought others might find of interest. Called Voltage Meter with model 
W002. In the electronics
    area.
