The Wouxun SPS30 III is a 12v switching power supply that can turn your mobile two way radio into a base station.
In this video, Danny from Buy Two Way Radios unboxes this powerful, yet amazingly affordable power supply and shows you how it works.
Not bad at all. Good features and good price point.
We have one connected to a KGUV920P at home and it does the job when my son and I are on evening and weekend ragchews.
