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! 
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.
Maybe someone will offer to pay for a flight to the UK so you can test some power solutions there
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?
I’ve used a ChargeTech 54000 mAh hour battery for a pretty good run. It has two 110v grounded outlets.
how long you think you could run that setup for on that battery?
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.
Looks like a good option! I’m surprised I never came across that when I was researching options.
I bought the Aimtom and so far so good. Had a fun but chilly jam on the beach.
Here’s my article on portable power if you’re interested: https://ask.audio/articles/on-the-road-portable-power-options-for-synthesizers-electronic-instruments?fbclid=IwAR2mBm4T9oDWyC7Zz7i-ceWo2JOyfmqhIqArVq4tj54iL2dwnhFTuvSj7Qw
Great, thanks!
BTW, “Ann Annie” is a he, not a she. 
Are there speaker modules anywhere? (it doesn’t have to be intellijel who makes them—just whisper using italics when you’re talking about another manufacturer so the Canadian robots don’t get jealous)
Intellijel briefly made a speaker called the Boombox, so you might be able to find that around.
Otherwise Ladik and Critter & Guitari make speaker modules. Not sure how good they are though.
If Canadians get jealous, we just quickly apologize and move on…
I’m quite happy with my latest Modular By Nature video. It gradually turned into this trippy ambient dub techno groove: https://www.youtube.com/watch?v=brcR6uhT4yc
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 
If anyone is interested here is a video of it in use: https://youtu.be/2D8sI-lE4FA
Really really nice stuff. Were you able to use one of the included barrel cables directly to the 7U?
If anyone’s been interested I have a bunch more portable jams on my youtube channel. Here’s the latest one: https://youtu.be/Y3oBZsdDxGA
