Mine here are all 5/9/15/20V.  I "think" they're missing only 1 or 2
voltages, but that's enough for my laptops and cell phones.  Not really
sure what'd ask for 9 or 15 volts ... 

Bear in mind that it's ONE output, and you negotiate the voltage on the
wire as part of the connection handshaking (IIRC CC1/2 or maybe
something more active later on, been a bit since I read up on how PD
works)
