The Hensel Porty Premium is a portable studio lighting power pack. This baby supplies a whopping 1200 watt/second of asymmetric power in a compact, water resistant pack. Add to that a built-in wireless receiver and quick change battery cartridge and you are set to bring high quality studio lights anywhere you can imagine. Want to do a photo shoot on the beach, or in the middle of the desert? This is the answer. No more worrying about if there will be power available at your location or having to lug around a generator.
A portable power pack has always been one of my objects-of-desire and I just recently had an opportunity to finally pick one up at a great deal (and I mean a really great deal). You wouldn't think a battery pack would be all that expensive. But these things retail for an amazing $2,600 without any lights OR A CHARGER! That's right, it doesn't come with a charger. That will set you back another $350 plus $500-1000 for each light. Definitely not for the faint of heart. But when your photography requires powerful studio lights in remote locations, the porty is the answer. There are other cheaper solutions out there like pure sine-wave inverters strapped to car batteries, but I prefer a unit that won't blow up when something goes wrong. Never a good thing to burn down a clients home or melt the fur off their dog. And who wants to carry around a car battery?
