Inverter generator with 10.5 hours of power, a Smart Throttle load feature, and extremely lightweight design
If you’re looking for an extremely portable generator that still provides a lot of hours of power, the Yamaha EF2000iS is a good candidate for you. It’s an inverter generator, which means it uses clean and reliable pure sine waves to generate electricity, and in Economy mode, it can run up to 10.5 hours during an emergency or any other time you need power, like at the cabin. Features like a Smart Throttle load factor into the Yamaha’s overall efficiency and CARB-compliancy, and it’s extremely lightweight design makes the generator truly convenient and truly portable.
The EF2000iS gives out a max of 2000 watts using an inverter system. This means it creates its energy using pure sine waves, so the resulting electricity is cleaner and more reliable. More fragile tools that are prone to short-circuiting or damage by unrefined energy will be better suited to the inverter.
10.5 hours in Economy mode
Because the engine is an overhead valve engine, the generator as a whole is more fuel-efficient. It’s so efficient it’s been awarded with CARB-compliancy. When the generator is in Economy mode, you ran run it without refuelling for about 10.5 hours, which is great for emergencies like power outages where you need to keep your fridge running and charge all your phones.
Smart Throttle load feature
Another way the generator earns its CARB label is through the Smart Throttle load feature. This allows the Yamaha to adjust its engine speed based on the amount of electricity being given out, so the engine isn’t always running full speed depending on what you’re powering up.
Generators can be loud and when you need to run it for hours on end, that noise can really wear on you. This generator is designed to block sound and is made of glass wool, which is ideal for absorbing noise even when you’re running the generator at full force. Combine these features with the muffler, and you have a very quiet generator.
This generator can recharge batteries with its 8A12V DC output, so you don’t have to rely entirely on the generator for all your devices and vehicles like RVs, boats, and cars.
Many portable generators can weigh upwards of 200 pounds or more, making that label a little iffy. The EF2000iS is only 44 pounds, so it is actually very portable and is designed to be carried around. It’s very convenient for camping and even to keep in your car for on-the-road emergencies.
Not enough power for big energy consumers
Besides charging car/boat batteries, about the biggest thing this generator can handle is a fridge. 2000 watts isn’t the highest amount of energy out there, and more energy-sucking tools and devices might overload the generator. If you need a generator to power up an entire house or cabin, you’ll probably want to choose a bigger model, but for less serious emergencies or device-specific power-ups, this generator is a convenient size and has enough power.
The Yamaha EF2000iS 2,000 Watt OHV Gas Powered Portable Inverter Generator is one of the more energy-efficient and truly portable generators out there. It’s CARB-compliant and uses an inverter system to generate cleaner, more reliable energy for charging batteries, home appliances, and more. For really big power jobs like supplying energy to an entire house, you’ll probably want a more heavy-duty generator, but for only 44 pounds, this little Yamaha can give an impressive 10.5 hours of quiet, refined electricity.
