Quite operation that cuts back on gas and fumes.
Weighing in at less than 30 pounds, the Yamaha EF1000iS is an ultra-portable power solution that powers anything in its capacity for a good 12 hours on a full tank. It features a simple design with clean easy filling, a decent power output at 900 Watts and the ability to filter out noise through the sound reduction system. This is an intelligent unit that is capable of sensing changes in load and accordingly adjusting the fuel throttle. It is CARB compliant and comes with a two year consumer warranty.
About the Yamaha EF1000iS
First off, the Yamaha EF1000iS isn’t your powerful compact generator, it is more of a temporary solution or a portable answer to specific needs. Do not expect to operate your entire range of machinery from the power generated by this generator. To start with, it has got a nominal output of just 1000 Watts, which is actually a sober 900 watts enough to power a single heavy machinery. It is built using an inverter system that helps generate more power from less fuel and produces perfect sine waves that is more reliable and dependable. As for usability, it works great in power outages keeping a large refrigerator powered up plus a few fans and couple of CFL bulbs. Just don’t try to overload this little beauty, it can trip and needs a manual restart.
The low power output and use of sound reduction technology together actually help drop noise levels by a good 10 dBA over its elder 2000 Watt rated sibling. This particular generator uses noise absorbing glass wool construction that dampens noise levels and helps keep it at a minimal sound level. Add to this its minimal weight of around 27.6 pounds and you get a lightweight generator that is going to pass any nature trail requirement. I have taken this along on camping trips that stretch over a week and powered my cell phone, laptop, a 2.1 speaker system and had juice leftover for the night to keep two table fans running on full blast throughout the night. The 12 hour battery backup, officially suggested by Yamaha actually applies to full load and not partial output. The Yamaha EF1000iS can actually recharge a few batteries for you with the 12 Volt DC outlets, which is an excellent addition for boat owners, auto or RV enthusiasts.
On a final note, the Yamaha EF1000iS offers exceptional fuel efficiency and a decent warranty cover, with the dependable name of Yamaha. One thing is for sure, the engine on this inverter generator is not going to fail you within a couple of years and if it does, the warranty covers replacements and repairs free of cost.

Won’t power everything in your RV or home so don’t try to overload it as it will trip continuously. Also, tends to maintain a medium setting by default so expect a sudden surge when you connect an additional load to it. Expensive considering its limited 1000 Watt maximum rating.
