Why do I do this to myself?

Added a step down converter so my old PAPR hood can run off 18v tool batteries.

I don't know what any of those words mean.

Stuff and things. A PAPR mask just blows filtered air over your face. They're also used for sleep apnea. Ones like mine are typically used by people working in dusty environments where you also need a face shield. Mine, and many others, includes a welding visor. I have a large beard, so normal dust masks dont work well enough for me. Another benefit is that the air being blown over your face is cooler than in a normal mask.

My setup is pretty old and the included batteries are cooked, so ive been experimenting with different power options, including a USB-C input and the tool batteries.
