Alternative / portable power for 7U cases


#21

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!

Right now I’m leaning toward the Aimtom SPS-155

Cool, thanks.
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! :wink:
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’ll definitely consider UK wigglers, but I wont have any way of testing how products made for that market would work. I’ll be sure to spend some time checking out euro alternatives though.


#25

Maybe someone will offer to pay for a flight to the UK so you can test some power solutions there


#26

I am considering this one. Any thoughts?

And does it have to be a pure sine inverter for eurorack (usually more expensive from what I can gather, and for more delicate equipment)? The one linked above has a modified wave apparently.
Thanks.

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?
