Wherever you need power, the Yamaha EF2200iS Portable Inverter Generator can bring it to you. This portable generator is made with a peak wattage of 2,200 and a running wattage of 1,800. With that level of output, you can power a television, refrigerator, and a computer all at the same time with wattage to spare. This portable generator can also power multiple tools like a saw or air compressor. So if you have a job site or campsite with multiple people, you can take care of all of their power needs with this 1 generator. There's even an RV outlet for use with a camper. But a high power output isn't the only important part of a generator. With sensitive electronics like computers or phones, it's important that the power comes out consistently. Otherwise, the appliances can get damaged. Because this generator is an inverter generator, it's able to deliver electricity at a highly consistent rate, making it safe for smaller electronics to use. One of the things that sets this portable inverter generator apart is the Smart Throttle feature. The smart throttle is able to tell the engine to relax or work harder based on how much power you're pulling from it. That makes the engine more efficient since it'll only be running as hard as it needs to. This feature also lets the generator run more quietly. At 0.25 load capacity, this compact power generator only produces a sound of around 57 dB. That's about the volume of a soft conversation. With the ability to run for over 10.5 hours at 0.25 load capacity, the Yamaha EF2200iS Portable Inverter Generator can be a reliable source of power for all kinds of outdoor energy needs.
