Everything works great with my PP2+. But...
The PP2+ manual states 200 watt maximum draw on the AC auxiliary outlet (don't plug your amp in here). The effect I want to plug into it says the adapter is 12VAC 1000mA and it uses two preamp tubes but it doesn't state the wattage draw (Electro Harmonix, Wiggler).
Is there a formula I can use to find the wattage draw out on this or other devices so I don't have to ask questions like this?
(Volts???Amps??? = Watts)?

E x I = P

Multiply the Voltage(E) by the Current(I) to get Watts(P).

This would be 12V x 1A = 12W

Generally a wall wart adapter will always be fine to use from the Courtesy Outlet.

Is the Courtesy outlet able to power another PP2+ or an ISO-5?
I did not find any wattage specs in either manuals.

In fact I am using a PP2+, but I have more pedals on my board a single PP2+ can power without daisychaining....

It is perfectly acceptable to power any Pedal Power unit from the Courtesy Outlet of any other Pedal Power unit.

Thanks, that's good news

(Newbie disclaimer...) I want to use an EHX Q-tron that comes with a 24 volt DC (inner positive) / 100mA external power adapter. Could I plug that into the pedal power 2 auxilliary 200 watt jack? Or is it necessary to use two of the standard pedal jacks to power the Q-tron?
