Hi Mex,
Thanks for the information. Now I'll have to hunt for a "real" surge device. In the mean time the plug in unit may offer some small coverage (even if it is about as useful as a leaky pot).
Looking at what is inside the Progressive Industries product shows they only have MOV technology--and not a whole heck of a lot of it.

I would imagine that Surge Guard is no better--but I have not found a photo of the guts.
BTW the Sola Basic is a "stepped" unit which has 3 layers of boost ( switching in at 110, 100 and 90 volts) and one layer of buck (135 volts).
It switches fast enough to react to surge from the air conditioner. It is quite delightful to see the voltage go UP by 3 volts when the air cycles on. I've observed this on 15 amp, and 30 amp shore power supplies where I was the only user.
