PocketWizard AC57-PA adapter

AC57-PA adapter

Here's how it works:
1. Plug the cable of your Canon compact battery into the AC57 power adapter.
2. Plug the AC57 Power Adapter into the side of your 580EX or 580EX II Speedlite.
3. Slide your 580EX or 580EX II Speedlite into the hot shoe of an AC7 RF Hard Shield and lock it in place.
4. Start recording.
It's that simple!

Important: We recommend that you do not connect or disconnect your external power cable to the AC57 adapter while the Speedlite is in the AC7's hot shoe. This may place some strain on the input jack of your flash.
