How to parallel two Honda Generators

Generators with Parallel Capability allows you to connect two portable generators, increasing or almost doubling your power output. So here is our guide on how to parallel two Honda Generators.

If your model does not come with an exclusive companion unit, you can still parallel most inverter generators with the help of parallel cables that have a 30-amp outlet.

These cables allow you to connect two of the same generators when there is no companion unit available. If you are wondering how to parallel two Honda Generators, then this article is for you. We have prepared a simple step-by-step guide to take you through the whole process.

With Parallel operation, you can link two Honda EU2200i or EU2000i generators together using a special parallel cable kit to get as much as double the power output. This gives you extra power when you need it without having to trade up for a larger heavier single generator.


Operating a generator can be dangerous if used improperly. Always refer to the owners manual regarding the safe and proper operation of your generator. Generator exhaust contains carbon monoxide which is a poison you can’t see or smell. So avoid using a generator inside a home or garage even if the doors and windows are open only use it outside far away from windows doors and vents.

The companion versions of the EU2200i and EU2000i generators provide a built-in 30 amp receptacle. These models are designed specifically for parallel operation with another EU2200i and select EU2000i models.

You’ll be able to use the 30 amp outlet on the companion to draw the full combined power of the two units. It’s perfect for RVs and for home use with the transfer switch or wherever a 30 amp outlet might be suitable. You can easily purchase Parallel operation cable kits from authorized Honda power equipment dealers.

All EU2200i Honda generators can be connected to another EU2200i or EU2200i companion generator as well as select EU200i model generators that have specific frame serial numbers. The table below shows the compatible frame serial number ranges.

Compatible ModelsFrame Serial Number Ranges

To parallel, the EU2200i generator with another generator follow these simple steps.

Step 1

With both of the engine switches in the off position, connect the parallel cable labeled L to the left parallel outlets, then, connect the cable labeled R to the right parallel outlets.

Step 2

Attach the ground terminal from each parallel cable to the corresponding ground terminal on each generator and tighten each screw securely.

Step 3

Start each generator and confirm that the green output indicator is illuminated on each. If using the eco throttle be sure that both generators are set to Eco throttle ON, once both generators are started.

DC Charging Guide

The EU2200i models are equipped with a 12 volt DC charge port that when used with the Honda accessory battery charging cable can charge a weakened 12-volt automotive-style battery.


The DC charge function should not be used to charge the battery long-term as the voltage is unregulated which could damage the battery if left unattended.


Plug the accessory charge cable into the DC receptacle.


Connect the red lead of the accessory cable to the positive terminal of the 12-volt battery followed by the black lead to the negative terminal of the vehicle battery.


Start the generator with the Eco throttle switch off and allow the battery to charge.

Do not attempt to start any vehicle while the generator is running and the charr cable is connected to the battery otherwise generator damage may occur.


To disconnect the battery charge cable turn the generator off and disconnect in the reverse order of installation.
