Might be interesting to some people: Myvolts has a kickstarter two devices they call “The Alchemist” and “The Silent Alchemist”.
The Alchemist is a device that provides USB-C-Power to multiple devices from a variety of stationary (wall outlet) or mobile (power bank, solar panel, car battery etc.) sources, and apparently you can daisy chain several Alchemists to one power supply.
It has 4 outputs with 3A each, so one could power 4 Elektron devices (even a Syntakt that draws 1.5A).
In the Kickstarter, they offer packages that also contain a number of their Step Up USB-to-DC-connectors.
The claim you can even daisy chain one output to multiple devices:
They also have a bigger version called “The Silent Alchemist” that has 8 isolated USB-C outputs, which is designed to help with hum and noise in the setup.
There’s also a webtool (PowerMyGear) for planning setups.
The Kickstarter is running until June 20 and the rewards are supposed to be shipping in October.
Looks like two interesting products that - if they actually manage to deliver what is promised - might solve a lot of problems people currently have around powering their setup. That being said, it’s rather expensive, the reward bundles start at $200, so definitely on the pricier side of things.
Edit: I find these things do come with disadvantages that are worth considering: it appears wasteful to me that you require expensive USB-C cables and external converters (at $20 each) for running power to a barrel plug, and also it appears that you can use the USB-C ports on your devices only for powering the device, so everything that would rely on data via USB is lost for USB-powered devices.
Edit 2: If you create and save a setup on PowerMyGear, they currently give you a code for 15% off for ordering stuff on their website (not on Kickstarter, though). So if you planned to get some things anyway, here’s your chance to get it cheaper.
Edit 3: The PowerMyGear app is nice in theory but needs more work, it sometimes won’t connect the devices you added, a lot of gear is missing, and there is no button to report obvious errors like this one:
