5v Micro USB to 9v Battery Adapter

thingiverse

I have a Rode Video Mic Pro that constantly requires battery changes. Frequently, I use it as part of a setup, so 5v USB power is readily accessible. The screws are aligned for secure contact on the inside and line up perfectly with the 9v battery profile. Step-up converters come with instructions, which I simply followed (adjusting the screw) and tested the output voltage. I found the converter on Amazon here: [Icstation MT3608 Micro USB DC Voltage Regulator Step-up Converter](https://www.amazon.com/gp/product/B01N9ZVXTR) All USB cable ends I've seen are too long to fit completely inside the housing. With a soldering iron, I eventually made one where I cut off a cable end and attached it directly to the soldering pads on the board. Then I drilled a hole where I needed the cable to come out. Although a cover isn't necessary, I created one just to cap things off.
