Find out in this review whether the Yamaha EF2200iS is any good so you don’t invest all that money in only an average generator.
Yamaha EF2200iS review in short
The Yamaha EF2200iS is an alright small inverter generator for small power needs during camping, tailgating, DIY session, etc.
Its 30 amp outlet makes it easier to connect to certain RVs and campers.
That being said, because of the expensive price and a few cases of issues, you will likely prefer other good 2200 watt generators.
For example, the WEN 56225i 2250 is more budget-friendly, quieter, and seemingly more reliable.
Additionally, the Powerhorse 2300i is a more reasonably priced alternative with a 30 amp outlet.
Pros
- Easy to carry around
- Compact dimensions
- 30 amp outlet is relatively easy to connect to RV (but don’t expect 30 amps)
- Has a CO sensor
Cons
- A few cases where customers got a Yamaha EF2200iS that did not work
- Expensive for this power level
Some of the best uses for the Yamaha EF2200iS include:
- Camping
- RV’s
- Tailgating
- Running certain power tools
- Boat trips
- Fishing

Some of the bigger devices the Yamaha EF2200iS should be able to power include an electric grill, a 10k BTU window AC, or a hair dryer.

Yamaha EF2200iS outlets
The outlets of the Yamaha EF2200iS are somewhat unusual for this power level. They deserve some extra attention in this review.
More specifically, the 30A TT-30R outlet does not actually offer 30 amps of power.
Due to the 2200 starting watts and 1800 running watts, the Yamaha EF2200iS “only” offers 18.33 peak amps and 15 running amps.
You may wonder why this small inverter generator then has the 30A TT-30R outlet.
The answer is that this makes it easier to connect the Yamaha EF2200iS to certain RVs or campers without too many adapters.
Yamaha EF2200iS customer reviews insights
The specifications of the Yamaha EF2200iS are still an important part of the review.

There are sometimes generators that good look in terms of specifications but have technical problems relatively often.

Whether this is an issue of certain retailers or the Yamaha EF2200iS itself is not entirely clear.
Since Yamaha often delivers (although in a pricey way), the EF2200iS gets the benefit of the doubt from me.
