The Yamaha EF2200iS is here to close the gap in range, and while it’s small, it’s powerful enough to power your caravan air conditioner.


The Yamaha EF2200iS inverter generator sits between the smaller EF2000iS and the larger EF2400iS. It has an extra 200W compared to the EF2000iS while being smaller and lighter than the EF2400iS. And this extra 200W of power means it has enough grunt to run your caravan air conditioner. The important part here is that the AC draws more load at start-up than it does when running, so the generator you choose must have the capacity to manage that initial need. This Yamaha model has a peak capability of 2200W but is rated at 1800W AC output. While many caravans these days offer solar power, there are still times when you have to get the generator out. Of course, some people will oppose the use of generators because a noise, but the EF2200iS is quite quiet, Yamaha claims 57~65dBA.

And like the rest of the product line, the EF2200iS is easy to use. There’s an easy-to-read multipurpose LED indicator, it has three handles, it weighs 25kg dry, and it measures 555mm x 300mm x 470mm, so it’s small enough to fit in the front storage bin of most caravans, or even on a fridge slide. The EF2200iS is also easy to get started with, just turn the front dial to ‘walk’, pull out the choke completely, pull chords quickly and fire reliably.

And for those who aren’t on the road all the time, and need to be able to store their generator, the EF2200iS has a fuel drain switch. This means that when you go to store it, you don’t have to worry about it leaking in your caravan or vehicle or ending up with stale fuel in your generator while you’re using it.

Yamaha claims the EF2200iS will run for up to 10.5 hours with a 4.7 liter fuel tank, saying the Smart Throttle function which adjusts engine speed to match the load means the unit runs with increased fuel efficiency.

For charging purposes, the Yamaha EF2200iS has three output sources, two AC outputs, and one 12-volt cigarette lighter style output. In our tests, we plugged in as many devices as we had – camera batteries, laptop chargers, etc. – as well as using a generator to run the AC Dometic FJ2200 in our Ezytrail Ceduna 13 caravan and it handled everything without drama, indeed, never showing a load above three lights.
