Thanks to all, elektrona answered me and they say that i can charge he battery case with the gas generator while using it. But, as UlFKrentz said, it's fast to give the energy but slow to take it from the gas generator. So i will run out of energy faster then the battery charges itself... Frankly i don't like the fact of pollution and a gas generator is not my first solution, but it seems to be the only practical one!
So UlFKrentz you didn't never experienced problems with those beautiful Honda with very delicate electronic devices? I'm going to use mostly my 7a 1200w pack do you think that the 20i is enough?
Again, many thanks!!!
Hi Michele,
we don´t own Profoto gear, so I cannot state if it will work, but I don´t see a reason why it shouldn´t. That Honda 20i is working very well with all equipment we ever tried, we use Bron Grafit and Scoro packs with it. Like I posted before there are also other solutions that are working, including battery powered systems.
You may ask at some rental houses if they have experience with Profoto packs on gas generators or could somebody else here please state something?
In general here are my thoughts, based on my experience:
1. Buy cable. Even if you have 300m of distance it´s still the cheapest and most reliable solution.
2. Use gas generators. Working fine, don´t need much attention. We prefered two of the smaller 20i paralleled. You can carry them alone, and in case one unit should fail (which didn´t happen until now) you have a second one and could go on working somehow.
3. Use battery powered systems where you can´t use gas generators or for small (short) jobs.
All battery powered systems are heavy, need quiet a lot attention, you have to keep your batteries charged and stored carefully. You only have the energy that is stored in your batteries, even less, when it is very cold outside, so you will have more batteries than you really need or run out of power on one of your next jobs. You need to replace batteries from time to time. So regarding pollution, I really don´t know what´s worse. Batteries have to be manufactured, charged even when not in use and at their end of life you have a harmful piece of junk, LithiumPolymer power doesn´t help here either. The Honda generators are not very noisy and I am still astonished, we never had to refuel them on a job. So put them a bit apart, they don´t need to be placed next to the model.
Patrik stated the flashfeeder has a 24V Battery, so forget my advice to connect it to your car (unless you a driving a 24V powered truck) and I am not sure about the battery charger output of the Hondas as well.
Cheers, Ulf
