I use my Honds a LOT. My 30 amp twist lock adaptor is a quality piece. I have neve seen a 15 or 20 amp adaptor that doesn't look like a toy in comparison... So the 100.00 is worth it to me... Plus it gives me ultimate flexibilty as to which generator to use.
My only point was that it seemed you were mislead by a tech as to the ability to use a companion by itself.... You can. Whether it is worth it to you is between you and your wallet.

The plug that came with the standard unit is the widely used 3-prong. How much more flexibility you demand is a bit of a stretch.
I made my own 15 and 20 Amp adaptors out of industrial grade electrical devices since I have access to suppliers with my electrical license. So, I'm quiet familiar with devices that don't look like toys.
Your point is taken: Camping World Tech may have been "enticing" me to get the standard since I really planned on buying two. But for now I would like to see how this Honda works and get the Companion later.
All the best.
