I had complained that I had discovered that my HF radio could only use the upper 58% of
a lead acid battery charge because it's minimum voltage requirement was above the minimum
produced by a nearly discharged lead acid cell.

I was told devices to take a variable input DC voltage and produce a constant 12 VDC output
were very expensive. Turns out that's not entirely true.

This device takes between 9 and 18 VDC in and produces 12 VDC out, at a max of 50 watts.

And for $32.49. That's a fraction of what I was lead to believe the prices were.

I've decided to order one of these power management devices. I'll let you know what I think of it
after I've had some experience with it.
