USB power banks are very handy for charging your phone but with KOMA Strom Mobile you can repurpose them to power your synths, drum machines and sequencers.

They are made, of course, for the KOMA Field Kit but there’s no reason why they couldn’t run any other devices that take 9v or 12v power. The first thing to understand is that they are now power bricks themselves, but rather they are adapters that take USB power and converts it into something more useful. The Strom Mobile can accommodate 2 power banks, creating two power channels each with 2 outputs giving you the power to run 4 devices (or more with a daisy-chain cable). There are some handy LEDs showing how much current you are using.
It’s totally brilliant and I can’t believe no one has thought of it before. Perfect for getting out there, off-grid and making some music.

The 9V/12V DC power output is clean and low noise and you can set each channel to either. In the box you get cables for USB and DC-DC power and a printed manual.
Cables
You can also pick up a cable pack which doubles up on the USB and DC-DC cables but also includes a 1-to-5 daisy-chain DC cable and a polarity changing adapter.
The Strom Mobile is available now for €175 and the Cable Pack is €35. Below is a video of the device in action, along with some music being made by devices powered by it.
Update: Of course it’s been thought of before, particularly in the guitar market. You can get adapters that will let you power 9V guitar pedals off USB power banks. Something like this is under £20, although you can get generic Amazon ones for a fiver. This from Mugig will handle a number of pedals for $25. The Strom Mobile has more features, dual channels and 12v power but is perhaps seeming a little expensive in comparison.

FYI A company called Mugig makes a similar product (Power Station) for less than $25 on Amazon. Only outputs 9V, but works as advertised.
Good tip – i’ve amended the article to reflect this.
