Review on DZS Elec Adjustable Electronic Stabilizer Tools & Equipment by Bobby Posner

This worked well for my hobby applications for example. arduino/raspberry pi and 2S lipo/8cell nimh applications. I usually output 5V or 3.3V. If you care, it has a really "high" quiescent current, ie 5-10mA, but I guess it wouldn't matter/would be anything else to most people choose if you would care. Just look at the data sheet and maybe then confirm if the claims are legal.
