There are cheaper powerpacks, and cheaper to make one yourself. But this is a nice all in one package with radio! lol $130 and has a 28AH battery instead of the AlienBee power packs with 20AH battery for $299 +sh. So 1/3rd the price and 1/3rd more power. Seems like a good alternative.

excuse my ignorance, but you always see the warnings about 'pure sine wave' crap and all the compatibility issues... can you say with confidence this will create no issues?

If the lights are designed to be plugged in to standard wall outlets, I'd feel perfectly fine plugging it in to the Duracell. When you get down to it, an inverter is an inverter, and while one may offer you recycle times or something, I don't foresee any problems at all with an off the shelf power pack.

just my $1/50.

Where are you reading "pure sine wave" warnings, Drew? Unless you are referring to my radio slave sync issue -- but what else have you heard?

I agree with Brandon, don't think there should be any issue as long as it is an AC plugged device.

Hold on here --- is this Duracell product a "pure sine wave" inverter at all??? If not, it will not work with capacitors (which is what monolight strobes really are.) Someone correct me if I am wrong, but I have tried it out using a marine battery and a cheap regular inverter with no success.

You have to use an inverter with a pure sine wave or you will blow your alien bee. A quick look in the strobist group or on the alien bee forums willl back this up.

Right... the duracell powerpack uses a modified sine wave, which doesn't work with alienbees in it's stock form. But, my plan for my use is to use it with a generic strobe of some sort. Most likely it'll be picky too, but there is most likely a solution to this.

Has anyone tried a UPS with this? I realize it's just basically just an inverter, but....

Maybe I ought to just take my UPS to work and start playing around with test equipment.

Yeah, if I were to buy nice lights I would bite it and buy a nice pack. No sense in possibly destroying a great deal of equipment to save a couple clams.

So are you going to take the Alien Bees out in the field? Otherwise you can just plug them into the wall. Someone correct me if I am wrong.

UPS I think use the modified sine waveinverters, or most of them do anyways unless they are higher end.

Since I capacitors I think only get charged up through dc current, the strobes probably step down the 120vac to something dc. I'm almost tempted to buy one of those cheap china strobes and have a look.

brian you are right they plug right into the wall. but it sucks when you have such nice light in guy and are stuck too a wall outlet. I'm thinking about making my own. I have just about everything i need. erikseo.com/blog/2008/how-to/diy-vagabond-portable-power-...

lol, I have all that stuff laying around except the bag and inverter. Ebike building and strobe power packs are surprizily similar.
