[NLRS] Re: battery booster

What is the actual mechanism used in these battery boosters?  Are they
a switching converter that accepts say, 10 to 14v input and yields a
regulated 13.8v output? or is there some other kind of magic at work?

Other magic.   The booster provides the necessary power above the battery
voltage to assure 13.8 vdc at its output.    For example, if the battery
voltage is 12.0 vdc, the booster provides an additional 1.8 vdc so that the
(battery + booster) system output is 13.8 vdc.    The advantage of this
design is that not ALL the supplied current runs through the booster ; only
that that is needed to assure 13.8 vdc.    As such, the device is
physically smaller and is more efficent.    I use one for my 10 GHz work
..... for those who have seen it I have the booster strapped to the side of
a large deep cycle battery and it connects to my systems via a PowerPole.
I've used the same power system for field testing and other work from time
to time.    Works well.
