Honda 2000i vs. Honda 2000i Companion


I have a couple questions about the Honda inverter generators that I'm hoping someone on the forum can help us with. I've copied them below. Thanks in advance!

- If our budget only allows us to buy 1 2000w generator, should we purchase the 2000i or the 2000i Companion? In the photos of the generators online, I see that the Companion model has the 30 AMP receiver built in, whereas the 2000i does not. So, I'd assume we should buy the Companion model so we can plug in our 30 AMP cord, but want to check with the experts first.

- If we can buy 2x 2000w generators, should we buy 2x Companions or 1 Companion and 1 2000i? On Amazon, you can buy a bundled package, which saves some money, but delivers 1 Companion and 1 2000i. My concern with this approach is that every time we only need to use 1 generator, we would have to use the Companion because it has the 30 AMP receiver. My concern is then if we allocate the bulk of our use to one generator, we wear that generator out faster.

Thanks in advance!

The standard practice is to have one of each when linked together. I don't know if you can connect two companions together, that's a question for Honda.

If only buying one you can buy either generator and use a 30A to 20A adapter for the non companion. One generator won't give you enough power to need more than 20A.

Similarly if you have one of each and are concerned about using one more than the other you can alternate generators by using the adapter when you don't bring along the companion.
Imo, I don't think using one generator more than the other is something you need to be concerned with. I don't think anyone has worn out one of these generators, i bought my set used from a construction company that used them to run portable traffic lights. I'm sure they have a lot of hours on them but they still run like new, start on the first pull and don't use oil.

The companion would be preferable to get one of, even though you still can't run the air conditioner with it alone.
As for purchasing two, you only need one companion, a regular 2000i will connect to it, and the trailer will plug into the outlet on the companion.

I bought the companion first, since I caught it on sale. But it really does not matter which you buy first.

There is no need for two companions. One of each is the way they are designed to work together. If you look at either model you will see two round single opening receptacles labeled "parallel operation outlets". (two side by side) That is where the cords plug in that combine the two generators.

My companion has a twist lock receptacle, not an rv receptacle, so I cannot plug the trailer cord in without an adapter.

Solid advice above.

Note that whichever generator you buy first will require an adapter to connect the 30amp power cord. The non-companion will need a 20 amp to 30 amp RV adapter. The companion requires a 30 amp twist lock to 30 amp RV adapter (your power cord end is not the twist lock standard it is what's known as a "30TT" for travel trailer).

I have one of each generator both converted to LP. Pics in my gallery if you want to see that arrangement. I have the proper adapter in each generator so I alternate use when I need only one but parallel them for AC and run both.

If you bought Yamaha 2,000 watt units they would be identical. The parallel cord used to connect the 2 generators together already has the 30 amp RV receptacle. No need for anything else when running in parallel. You will still need a 20 amp adaptor if you run only one generator.
PPL motor home usually has good prices on Yamaha generators.

First buy the single, then the companion. For very little money you can buy a converter to hook up the single. I started with one and then got my companion. I think they are very good. Have had the first one for 5 years and it works great, no trouble. Be sure and use fuel stabalizer in the winter.

Starting an AC is the issue. Some AC units can be started with a 2KW generator. The key is that the AC be equipped with a "hard start" capacitor (which often can be added to as an aftermarket upgrade). Once started, an AC unit needs far fewer amps than what was needed to get it started. I'd buy the Companion model (usually about $100 extra). I had a 3KW Honda Handi which was a sweet little unit. Powered everything on the 17' Casita Travel Trailer I had at the time.

We have two Honda 2000s... We got the Companion first, along with the paralleling cable (which is very simple and easy to use), figuring that SOMEone would have a regular 2000 if we really need to establish a cool trailer at a campout or rally... before we got the 2nd regular generator. We got the regular one later. The advice above is solid. You will need an adapter for either generator...a 20-to-30 for the regular one and a twist & lock to regular 30-amp plug in for the Companion.. BE SURE to have these before you head out for a trip! These machine are highly reliable and user friendly. You can do you own maintenance if you wish ... we do our own oil changes, and the minor stuff, but take them to a Honda dealer for service about once a year for the more in-depth stuff. Be sure to drain the gas tanks AND carburetors if you plan to let the generators sit idle for more than a month without using them.

Just to be clear. You will not get 26 amps out of the companion generator without the 2000i run parallel with it. Therefore, you cannot run your air conditioning until you have both.

We have one of each. Companion has the advantage of the 30 amp outlet, and the regular 2000i has a 12v charger outlet that can be used if you have trouble with Tow Vehicle battery.

I've had a pair of 200i's for a while. Had a Honda 3000 that worked like a charm but was too heavy to lift up into the bed of my 4WD pickup. My electrician friends said that the plug was the limiting factor in output so I got the parallel kit that had the right plug. It was a little more expensive but now I can run all kinds of stuff at the same time without any issues. Mine is older but I THINK this is the Honda part number 08E90-HPK2001. But it does come from Honda so a dealer can help you with that. I think the risk with generators isn't that you wear them out but rather there are issues from lack of use. I always use both even though I rarely need both.
