[710] Awesome battery pack. I use it on location and it works perfectly with my 202VF heads. The fans are disabled when using with the pack. The only drawback is the weight if you have an assistant holding it while shooting.

[53] I've purchased these before, for guitar pedals, but also as a power source for a small project. This instance was no exception... they're good power-supplies.

[53] I use this primarily in the studio and along side another 2403cx and a 4803. This pack is very versatile and easy to move around.

[710] Adding in some newer packs to supplement my equipment. Speedotron works well, is reliable, doesn't cost an arm and a leg, and don't need repairs too often.

[53] I am a professional portrait photographer. Great for in the studio and light enough to shoot on location as well... but only if you feel like lugging 28 pounds around with you not including the heads. Fantastic light quality, extremely well built and solid like a rock. If your looking for pack and head system, this is the way to go for sure. Just about every pro I can think of uses them.

[710] I use this to power a guitar pedal rather than changing out batteries. Works perfect, no complaints.

[710] Just used it in an airport shoot. No trip hazard so battery power was needed. Ive had Blackline traditional HEAVY power pack for awhile (2401A). To be honest it was gathering dust since I've moved to Canon 600ez-rt speedlights. The need for real power lights are less and less in this clean-high-iso-camera era that doesn't need the nuclear blast of a 45 lbs of 80's American engineering encased in heavy steel. But when you do need some portable powerhorses there are the newer kids in the block like Profoto, Hensel.... I was about to starve and give up drinking for few months so I can afford these hipster Euro units but this Digital Explorer came to rescue. Since I've had some black line heads I bought this wonderful workhorse. I was impressed with this unit. the consistency of output, the sturdy workmanship, the well thoughout case. The power is enough to go through big softboxes, 7 ft umbrellas or the like. The bad: You can only do 1:1 ratio or 1:2 ratio. The variable knob adjusts both lights at the same time. you can't adjust them separately . Black line users are used to this but the lack of other ratio makes it less flexible. But honestly, I think most will use to this to power just one head with a modifier. So its not that bad. The other bad. The menu system is horrible. its like trying to program your 90's VCR. But once you get used to it, it only takes a few minutes to check the battery level... sheesh. Its powerful, the flash duration is pretty fast (on 103's) battery life is not too bad and best of all you don't need to starve or give up drinking to buy one of these things!

[710] I've owned Speedotron for several decades and find it to be the most reliable strobe equipment. I was hesitant about this pack because it was a new design and didn't know how it'd hold up. After a few years on location my doubts are history. This pack is very versatile and at lowest power settings there is excellent flash-to-flash consistency. .1 stop according to my Minolta Flash meter. I was shooting on a football field late at night one time and when the sprinklers went off three feet away, I thought I'd see the power supply short out. Even though it got some water splashed directly on it, the pack didn't die. We finished the shoot and as a safety measure I sent it in to Speedotron's renown service department and it came back two days later without any problems or need of repair. The only down-side to this pack is its weight. It's about 25 lbs., of which 20 lbs. is the battery.

[53] Out on location my go to is the Juice Box Battery for Explorer 1500 Power Supply. The great thing, its 100% less noise then your clunky generators. I have two of these workhorses and i'm very confident out on location.

[53] I've primarily been a studio photographer for the past 25 years, but recently more and more of my work has been on-location. I have always used Speedotron so I have enough of their gear to light a city. These Explorers allow me to take all of my equipment anywhere I want. Durable, dependable, powerful. Best investment I've made in a long time.
