For a while, I've plugged in my studio strobes to one power pack. While that works, there are times I wish I had one for each so that the recycle time doesn't suffer as much and I can also have more shots per charge. The only thing is that the "cheapest" and most popular power pack (Vagabond II by Paul C Buff) is $300 a pop. Ouch.
...Then I saw this video.
