The Honda EM7000isAB combines power of the EM6500S with inverter and i-monitor technology to serve needs at both the home and on trips. It can be used in close surroundings without disrupting neighbors because it only produces noise levels of 69 dB @ rated load and 63 dB @ ¼ load. Its i-monitor technology provides system information and assists in maintenance. Its inverter technology reduces noise, decreases weight, and increases runtime.  

Honda provides the optional electric start for convenience. The standard model EM700isAB comes with an electronic ignition, electronic circuit breakers, fuel gauge, muffler, and a 120/ 240 selector switch. For receptacles, it has a 20A 125V duplex NEMA plug, a 30A 125V locking plug NEMA plug, and a 30A125/250V locking plug NEMA plug. Honda’s Eco throttle technology enables operation for 4.7 hours @ rated load and 14 hours @ ¼ load on its mid sized 4.5 gallon fuel tank. It has Oil Alert to prevent engine damage. It is fairly large weighing 209 pounds and having the dimensions of 31.9 x 26.4 x 27.2 inches (L x W x H).However, the two wheel kit makes transport possible.

Additional options are a transfer switch to connect the generator to home electrical systems, a hanger kit for storage, remote control kit for convenience, and a storage cover for protection.

The EM7000isAB comes with a standard two year residential and one year commercial warranty.

Honda’s EB7000i is a heavy duty inverter model combined with i-monitor technology, which provides feedback to the consumer regarding his or her generator’s status and how it is performing (i.e. engine speed and wattage). This also proves to be beneficial when the EB7000i needs to be serviced or repaired.

Powered by Honda’s GX390 389 cc OHV engine, the EB7000i has a max output of 6500W. This is a powerful generator designed to supply electricity to various devices at the same time.

It has a capacity to hold 4.5 gallons of fuel which enables a run time of 4.7 hours @ rated load. The Eco throttle enables run times upwards of 14 hours @ ¼ load. This generator is perfect for a wide range of environments due to its quiet operation at 63-68 dB. It is a larger generator weighing in at 198 pounds. To add convenience and ease transportation, this massive machine comes with a standard two wheel kit enabling mobility. It also has many of the features common to Honda generators including, a fuel gauge, electronic ignition, electronic circuit breakers, 120/ 240V selector switch, Oil Alert, USDA qualified muffler, and a GFCI/ neutral bond. There is an additional option for a storage cover.

For receptacles, the EB7000i has a 20A 125V Duplex plug, 30A 125V locking plug NEMA plug, and a 30A 125/250V locking plug NEMA plug. However, it is important to note that this model is not compatible with home and isolation switches.

The Yamaha Inverter EF1000iS from Yamaha was designed to be convenient, versatile, durable, and applicable for many different uses. It is perfect for powering small refrigerators and microwaves either at home or on camping trips. It is extremely light at only 27.9 pounds. Which makes it also very mobile, many can easily carry it. This can partially be attributed to its small .66 gallon fuel tank. Nonetheless, it can operate on one full tank for up to 12 hours. This is due to Yamaha’s smart throttle load sensing technology, which monitors and regulates engine speed to increase efficiency.  This also aids in reducing noise levels. However, it is Yamaha’s Noise Block system that reduces totals to a range between 47dBA and 57 dBA. Often with larger louder models one must isolate them from others; however, 47- 57dBA is very tolerable even by those in close proximity.

Its OHV MZ50 engine with 50 cc of displacement and 2.2 hp produces a max AC output of 1000W and a 12V 8 amp DC output. The DC output comes in handy when recharging 12V batteries. It also comes with an inverter system with pulse width modulation control which ensures a consistent steady stream of clean energy. This enables one to power electronics with microcomputers. The dual coil alternator stator reduces fuel consumption by lowering the speed of the engine. The fuel petcock increases the carburetor’s life by allowing it to run dry. Overall, this is a highly convenient and efficient generator for smaller devices.
