Doepfer A-183-9

janky power cable, feels kind of cheap

If you need to:

Plug a USB light
A Microfreak
A Korg SQ-1
etc with a USB power

you need this

It’s build with the same quality materials as other a100 modules I believe, but for the task that quality standards are just not enough. Connecting any usb to the sockets is bending aluminium pannel. Also the sockets themselves have too much of movement while doing so. It’s evident the module won’t last, and you want it to if you buy one for 50€.
Pitty, but for me it’s a refund

I'm using this to power a couple of USB lights and external keyboard (Keystep Pro) and works perfectly. The build quality seems a little cheaper than other modules - in particular the connector was not the standard header but a "lite" version that seemed fragile - it's not a cheap module for what it is so would have expected more from that component.

Very simple module, does exactly what you expect. Make sure you have a 5V rail avaliable in your case, or it won't work! ((There are products like Kavis no-drain to get 5V from the -12V if you need it.))

Be wary that some USB keyboards etc are NOISY, ie, introduce a hum or buzz into your rack. There might be ways to alleviate this, with better cables etc, but i just used different keyboards.

I use this for powering a pair of Korg SQ-1's. No problems so far.
