Are parallel cables universal?

Honda and Yamaha simply connect the AC outputs together for paralleling. Most, possibly all, others use a proprietary connection with some sort of sync signal. Kipor's original parallel connection used the Honda/Yamaha method and Honda "sued the pants" off of them, and they changed to a proprietary connection. Honda has their parallel technology patented and it wouldn't surprise if it's cross-licensed with Yamaha.

I just posted this write up about the Honda parallel setup---

Connect Honda EU1000i to a EU2000i WITHOUT Honda's cord

That assumes the receptacles for the plugs are the same on the Champion and the Honda.

Well, the 120v sockets certainly are!

Thanks for the replies. I went out on a limb and bought the last parallel power cable for Yamaha generators I could find here locally. I didn't have time to wait for an online purchase. It fit perfectly with the Costco Smarter Tools generators (AP-2000iQ) and powered up my rv including the AC, so it worked out except now I'm $1300 lighter from two generators with tax plus $110 lighter for the "sidewinder" parallel cord.

No ... generic universal cables
Know nothing about the "smarter" line of gensets
But I do know the Champion line inverter generators use a special cable system (two power cables and a double set of syncing plugs)
The syncing plugs connect the two electronic brains control signals

I seriously doubt the Honda cables and smarter line cables are interchangeable

Yes, there's nothing special about the parallel cables, They just attach the outputs of the two gens together so if they'll plug in then they'll work as long as the gen is capable like Bobbo says.

Be sure the Smarter Tools generators can be paralleled. Not all generators can be. They have to be engineered for that functionality.

Yeah, thanks for that. The newer Smarter Tool model that Costco is selling is capable of being paralleled. .
