Design, Dimensions & Weight
Since this model is on the lower end of the power spectrum, it is more compact and less heavy than models with higher rated supplies. In terms of weight, it has a dry weight of 28.7 lbs.
Its hard plastic exterior is responsible for this sturdy yet light design.
It has a tank with a fuel capacity of 0.6 gallons or 2.3 litres. When this is filled to capacity with gasoline, this model can weigh around 32.5 lbs. This means that even on a full tank the EU1000i is extremely light, making lifting it an easy task.
Its dimensions are also sufficiently compact as it has a length of 17.7 inches, a width of just 9.4 inches, and a height of 15 inches. None of its dimensions exceeds even one a half feet, which makes it extremely easy to transport and store in small spaces.
Since it is so compact and lightweight, it comes with a convenient handle for carrying it but does not come with a mobility kit or wheels.
While Honda itself has not uploaded an official video of the EU1000i, there is a popular user-uploaded video of the model which you can view to assess its dimensions and suitable in real-life settings –
Power Output / Generation
The engine of this generator is manufactured by Honda itself and is labelled as Honda GXH50 engine.
While not much information is given about this engine type, it is stated that this is a four-stroke engine. This is crucial as it means that only 4-stroke engine appropriate oil should be used for this generator.
Honda doesn’t specify any one oil type for the engine. Rather, the manual in this model comes with a chart which lets you assess the oil type based on the temperature range across which you use the generator as well as the starting and ending temperatures of two consecutive usages.
In general, however, Honda does state that an SAE 10W-30 is fine to use over a wide range of normal temperatures.
However, you should definitely consult the manual if you use this general in locations with extremes of climatic conditions.
The generator is capable of producing a maximum power supply of 1000W while the rated supply is 900W. This is capable of power small electronic items and gadgets within your house such as fans and lights.
Furthermore, since it is an inverter generator it is capable of producing an extremely smooth output which means it can be used to power sensitive electronics such as computers or laptops as well.
In case the power output is too low for your use, you can also connect two units of this model in parallel with each other to generate a larger power supply, thus being able to meet more minor needs.
Fuel and Noise
The fuel for this model is unleaded gasoline with an octane rating of 86 or higher.
This octane rating should not be hard to find as most commercially available gasoline has an octane rating above 85. The gasoline must also contain less than 10% ethanol or 5% methanol by volume.
Stale gasoline should not be used. Neither should gasoline which has contaminants such as water, dirt, or oil mixed into it.
Its fuel tank has a capacity of 0.6 gallons or 2.3 liters, which is a relatively small tank size. However, this model is very efficient with power generation and can make a full tank of gasoline last for 7.1 hours on a quarter load.
In terms of noise, it is marketed as being extremely quiet. It has a decibel level of 59 dB at a distance of 23 feet.
While this is definitely quiet, brands such as Champion also manufacture generators with the same noise level so
Honda’s claim of being uniquely low noise is not completely accurate.
This model is CARB compliant which means that it can be used in all 50 states, including California.
Display & Control Panel
Most of the controls on the EU1000i are concentrated on one panel which is compactly laid out.
Despite being compact, each control is given adequate space and is labelled in a large, white font which is highly visible against the black panel, making it very easy to read.
The starter grip and the engine switch are located on the side next to the panel, rather than on the panel itself. The choke lever is also located on the opposite corner of the same side as the engine switch.
The following controls are present on the panel :
Eco-Throttle Switch: this is used to turn the Eco-Throttle mode on, which adjusts the speed of the engine to the power load on the generator to increase efficiency and hence conserve fuel and decrease noise
Parallel operation outlets: used to connect two units of this model in parallel with each other to increase available power supply
DC circuit protector: automatically shuts off the DC circuit if the battery being charged gets overloaded
Output indicator: is a green light which turns on during normal functioning of the generator – it is also a simplified hour meter as when you put the generator on, this light blinks depending on the number of hours it has been used for – for every hundred hours of use it blinks one time
Overload indicator: turns on when the generator is overloaded and shuts off the power supply to the loads while the engine continues to run
Low oil indicator: turns on when the generator engine is low on oil and shuts the engine off
Grounding terminal: it is used to ground the generator – consult local regulations before attempting to ground it
3 receptacles: it has a 12V DC outlet and a 125V, 15A duplex for AC
Startup and Shut down Process
This generator only has a manual start option. Electric or remote start options are not available for it.
Before starting the generator, ensure that no loads are plugged into it and that it is in an open space with ample ventilation. Also, ensure that the Eco-Throttle switch is OFF. After this, follow these steps :
- Turn the vent lever on top of the fuel cap to ON
- If the engine is cold, move the choke lever to CLOSED position and if it is still warm, leave the choke lever at OPEN position
- Turn the engine switch ON
- Pull the starter cord slowly until resistance is felt and then pull sharply
- If the choke lever was on CLOSED position, slowly rotate it to OPEN
Before stopping the engine, turn off and disconnect all loads attached to it. Then follow these steps :
- Turn the engine switch to OFF position
- Let the engine cool slightly and then rotate the vent lever on the fuel filler cap to OFF
- Optional step: In case you have connected two units in parallel, disconnect the parallel connection cables.
Honda is known for creating its own technologies for its generators and as such, each of its generators has special features which mark them off from other models available on the market.
The EU1000i has the following features:
Basic hour meter: the overload indicator light on this model functions as an hour meter – every time the generator is put on, the light blinks – the number of blinks start at no blinks and for every 100 hours of use it blinks one more time, thus functioning as a rudimentary hour meter
Eco-Throttle mode: this is a special technology developed by Honda which allows the engine speed of its generator to slow down when the load is less than maximum – this conserves a lot of fuel and dramatically reduces the noise level of the generator
Warranty and Repairs
The EU1000i has a warranty of 2 years if it is used for personal usage. However, its warranty period for commercial use is also extremely good as it lasts for 1 year after the date of purchase.
The Warranty can be availed only by those who have bought this generator from an authorized dealer by American Honda in the US, Virgin Islands, or Puerto Rico. It allows you to seek replacement of malfunctioning parts as well as repairs free of charge.
However, this warranty is voided if non-genuine Honda parts are used as replacements, unauthorized adjustments are made to the generator, proper maintenance is not carried out in a timely fashion, or it is used improperly.
For emission-related parts, Honda also has a specific Emission Control System Warranty which lasts for a period of two years, which is the same period of time as the warranty of the generator itself so users will most likely not have to avail of this warranty.
Honda also provides warranty on any parts, accessories, and apparel for the generator.
For private residential use, parts have a warranty of 6 months, accessories have 12 months, and apparel has 6 months. For commercial or rental use, however, they all only have a 3-month warranty.
