YAMAHA vs. HONDA 1000 watt Generator

Yamaha and Honda: these big boys lead the way in inverter generators. But despite appearances, Yamaha and Honda generators are not made exactly equal. The challenge for buyers is delving deep into the features to work out which provides the best value for your needs.  

The good news is we’ve done the hard work for you. Starting with the smallest of their inverter ranges – Yamaha EF1000iS and Honda EU10i – we’ve drilled down into the details to give you the ultimate comparison in one place.

On the surface, it’s easy to pass off these two inverter generators as the same. Both the Yamaha and Honda 1000W generators comprise inverter technology making them ideal for use with sensitive electrical equipment, such as computers and mobile phones. They’re both lightweight and compact – in fact their dimensions are exactly the same. They are both quiet and have a recoil start. And because of all this, they are extremely popular generators for the camping and recreational market. But their similarities end there.

Let’s look at the details:

Light Weight: In the battle of weight, the Yamaha EF1000iS wins hands down. Weighing a feathery 12.7 kilograms, it is the lightest 1000W portable inverter generator you can buy. The Honda EU10i weighs in at 13.2 kilograms. While half a kilo might not sound like much, but when you’re moving a generator back and forth on the campsite, you’ll want the lighter option!

Silent Operation: Let’s be honest, you can choose either of these models, switch them on and pretty much forget they’re even running. But thanks to the patented Yamaha Noise Block Sound Reduction System the Yamaha EF1000iS boasts super silent operation with only 47 decibels of noise at a quarter load, as measured at seven metres. That’s quieter than a normal conversation! The Honda is slightly louder at 52 decibels.

Fuel Efficiency: Don’t be fooled by the compact size of these 1000W models, the Yamaha EF1000iS can run for up to 11.9 hours at a quarter load before needing a fuel top-up. By comparison, the Honda EU10i lasts for 8.7 hours – three hours less than its Yamaha counterpart.  The Yamaha 1000W generator features a smart throttle, which automatically adjusts the engine speed to match the required output. This maximises fuel efficiency so you get more power when you need it. Similarly, the EU10i has an Eco-throttle. The Yamaha 1000W generator also has a larger fuel capacity with a 2.5-litre fuel tank over the Honda’s 2.3-litre fuel tank.

Top Features: The Yamaha 1000 watt unit comes with features you would usually only see on larger generators, such as a low oil alert, an AC plug and DC charging cord, and a spark arrestor. The Honda 1000 watt model does have something the Yamaha doesn’t – a Parallel Connection feature. This means that if you have two Honda EU10i generators, you can link them with a cable and double your output to 2000W.

Honda EU10i: The Yamaha EF1000iS is especially popular for caravan, camping and boating trips.

Warranty: With either of these inverter generators, you’re getting the peace of mind that comes with the strong Yamaha and Honda brands. Both manufacturers are famous for engineering the best power equipment in the world. That said, it’s still wise to choose a generator with a good warranty period in case the worse happens. Luckily, both the Yamaha EF1000iS and Honda EU10i come with a four-year domestic warranty, backed by a national service network.

The Winner

Looking at the comparison, the Yamaha EF1000iS is a clear winner. It is lighter, quieter and more fuel-efficient that the Honda 1000W model. The only added advantage the Honda has is the Parallel Connection, but that’s a feature you can only enjoy if you have two of the same generators.

    Hi would either one of these charge a set of three deep cycle batteries in a camping trailer?

    • My Generator Admin June 29, 2015, 12:04 am

      Hi Lars, The short answer is yes. The 1kVA inverter generators are very popular for charging your auxiliary camping batteries. Just be sure to use a battery charger between the generator and your batteries, as this will ensure the power is properly regulated and will not damage your batteries. Most inverter generators do have a DC charging capability, however this is not suited for charging for prolonged periods, and that is why we recommend using a battery charger between the generator and the batteries. Thanks, Steve.

    I have a C Tek25 watt battery charger that quotes a requirement of 2.9 ARMS. If I used this on the Yamaha 1Kva how much would I have left to use? Sometimes I would also need to plug in a 12 volt 7 Amp charge to charge two batteries at once. I presently have a Honda 2.0 and it does it easily but the weight is too much.

      Hi David, we’d recommend you find out the peak wattage draw for your particular battery equipment. Typically the Yamaha EF1000iS is a very popular choice for charging camping deep cycle battery packs (via a battery charger), but just to be sure it can handle all your charging requirements for your specific batteries, its important you first find the exact wattage draw. Thanks, Steve

  • David Hobbs October 8, 2015, 10:24 pm

    I know what you are saying, but I am having trouble calculating what an ARMS is in usage? It quotes a 100-240 v 2.9ARMS input?

    I have a caravan with 2 solar panels (135w each), 2 batteries (120w each) these work fine, until no sun. Is it possible to use a generator to top up my batteries by plugging a lead from the generator into the 240v, 15amp inlet on the van. What else will I need?
    Thanking you
    Annie

    • Lachlan June 6, 2016, 7:38 am

      Hi Annie – thanks for your question. You will need a battery charger to connect between the generator and your batteries. This will ensure the charge is regulated and the charge is done properly, without any risk of damaging any of your equipment. Using a Yamaha EF1000iS and a battery charger is a very popular way of charging camping/auxiliary batteries, especially when solar is not an option. Many thanks.

    I need to power an IP-camera and an internet router, so the power from the generator needs to be completely reliable and continuous. Would either of these be suitable for this use, and would I still need something in between of my devices and the generator?

    Thanks so much,
    Mark

      Hi Mark, a quality inverter generator from the likes of Honda or Yamaha will deliver pure sine wave power. These inverter units provide power as clean or cleaner than the power output from your home wall socket and therefore they are suitable to run your sensitive electronic equipment. One of our more popular units for your type of application such as running camera equipment and other small electronic appliances is the Yamaha EF1000iS – you can actually see a video on the product page of a customer using this generator for that exact purpose 🙂
      Many thanks
