Honda Parallel Cables for EU1/EU2/EU3i
Parallel capability is an additional benefit of inverter technology.
Using a special cable you can link two EU1000i, two EU2200i, two EU3000 Handi, or two EU3000is generators together to get as much as double the output. (Please note: you can only parallel two identical units together.)
This gives you extra power when you need it, without having to trade up for a larger, heavier generator. You get more power without sacrificing portability.
Honda also offers a special Companion version of the popular EU2200i with a built-in 30-amp receptacle. This model is designed specifically for parallel operation with another EU2200i. It's also perfect for RV and use with a transfer switch, where a 30A outlet might be preferable.
Parallel cables allow the user to obtain the full power of both units, limited by the capacity of an individual outlet. Parallel cables are available for the EU1000i, EU2200i, EU3000 Handi, and EU3000is.
If you have a regular EU2200i and the Companion model, you only need a parallel cord. You will be able to use the 30A outlet on the Companion to draw the full combined power of the two units.
