What cable do I use to power my external flash?

Flash unit has an input which says 330V DC in which is a 2 pin socket.

This is the kind of cable used to attach flash to pentax TR3 power pack.

But I don't know what workaround I can use?

Please advise.

Errr.....you can't do it. The VML is *NOT* the same thing as a Quantum pack... :-P

If I'm not mistaken, the Alienbees Vagabond mini II portable power gives you 120VAC. It is in essence a SLA battery and an inverter.

So now the question is how you can power the AF540FGZ from 120VAC.

Quantum has a product called Quantum Turbo AC (link) that converts from 120VAC to 330VDC. You need a Quantum CN3 cable to connect the Turbo AC and your AF540FGZ.

But why?

If you need to speed up the flash recycle time, get a Quantum Turbo.
