Will do! The difficulty of finding information and the amount of confusion out there made me think it would be a good topic for an article. That and the fact that it’s a problem I want to solve for myself!
I am in Europe so this particular model would not apply here I think. Just one more thing to consider for the article, different power specifications around the globe!
Thanks again for your help.
@ScottMFR Just seconding modular’s request that you consider users in UK/Europe in your article. There’s definitely a need for such an article – looking forward to it.
Regarding the USB PSUs designed for phones/laptops. Whilst these often have considerable capacity (40Ahr or more, which is plenty), most of them can’t pump it out at a rate sufficient for our needs. I’ve not found any that can deliver more than 2A or so. I reckon 4A would be better, as this has to be shared between all 3 voltage rails.
I kept researching and I believe I will go with a pure sine inverter battery. Another question I have is grounding. Portable batteries do not have a ground usually - is this a problem to use them with eurorack? Will it create electrical hum and/or static electricity/“floating” in the modular?
I could run the Intellijel rack itself for 10 hours on that battery, easily. The modules in it draw 888mA of current according to Modular Grid (plus power supply overhead). Of course powering speakers is the real draw, but I think practically a few hours for everything in the photo is a fair estimate, which includes the B&O speaker at full volume. You can’t fly in a commercial airline with that battery, but they make a slightly smaller one that is FAA approved.
First off I found this thread incredibly useful and filled with some really good info. Would just like to add that I got this one off ebay and is working great:
Guessing it will last around 4 hours with my 7u 84hp setup. Trying to go as lightweight as possible so I think this one is a good solution. Planning on hiking with it and filming in some mountains here in Alaska. This is actually why I chose this case in the firstplace
