Honda EU22i 2.2kW Inverter Suitcase Generator

Genuine Honda inverter power you can carry in one hand. The EU22i pairs Honda's 121cc GXR120 engine with clean inverter output, so a laptop, phone charger or TV runs on it as happily as a work light. At 21.1kg dry and 52 dB(A) at 7m, it's built for places where weight and noise matter: pitches, moorings and remote spots far from a socket.

Why buyers choose the EU22i

• Clean power for electronics. Inverter output suits laptops, TVs, chargers and other sensitive equipment.
• Quiet where it counts. 52 dB(A) at 7m, with an acoustically insulated case and advanced muffler, makes it a good neighbour on a campsite.
• Eco Throttle. The engine slows to match the load, which cuts noise and fuel use.
• Double up when you need more. Two EU22i units can run in parallel for 3.6kVA rated output, using Honda's optional parallel kit.
• Protected as standard. Oil Alert shuts the engine down if the oil gets too low, and overload protection cuts the power if you ask for too much.
• Two 13A sockets. Ordinary UK plugs go straight in, with no adaptor needed.
• Simple to look after. A maintenance door gives easy access for routine servicing, and the output light even blinks to show roughly how many hours it has run.

Is it right for you?

Ideal for: caravans and motorhomes on sites without hook-up, narrowboat owners moored near the bank, camping and remote trips, and modest professional loads such as a market stall. Honda's professional-use warranty is shorter, at 1 year.

Look elsewhere if:

• You need to run a full 3kW kettle, air conditioning or several large appliances. The Hyundai HY6250SEi gives 5kW of continuous inverter power.
• You need backup for a whole house. See our 5kW to 10kW generators.
• You need to run it for many hours between refills. See our long run generators.

What will it run?

Plan around the 1.8kW rated output. The 2.2kW maximum is for short bursts, such as a motor starting. Running slightly over the rating may not trip the protection, but Honda warns it will shorten the generator's life.

Example: fridge 150W + TV 100W + lights 40W + laptop 65W comes to about 355W, a light load that leaves plenty in hand. Add a 1,200W microwave and you reach about 1,555W, still inside the 1.8kW rating. Switch Eco Throttle off when you run several high loads together, as it helps keep the voltage steady.

How long will the fuel last?

The 3.6-litre tank lasts about 3.5 hours at rated output, and up to around 8 hours on light loads with Eco Throttle on. Use fresh unleaded petrol with no more than 10% ethanol, so standard E10 is fine. Don't fill above the upper limit mark.

Where to put it

• Stand it on firm, level ground outdoors, at least 1m from buildings and other equipment, and well away from doors, windows and vents.
• Never run it inside a caravan, awning, tent, garage or any enclosure, or with its covers removed.
• Never run it on a vehicle. Take it off and set it up in a well-ventilated spot. Honda also warns against leaving it in a hot, enclosed vehicle for hours, as fuel can vaporise.
• Keep it dry, and don't run it in rain or snow.

Earthing and connecting it

If your appliance is earthed, Honda says the generator must be earthed too, using copper wire at least as thick as the appliance's cable. If you run two or more appliances, Honda specifies a 30mA RCBO. Never connect it to a building's wiring without a qualified electrician, because power can feed back into the mains.

Before your first start

• Add engine oil. It takes about 0.4 litres. Honda recommends SAE 10W-30, API SE or later, for general use.
• Add fresh petrol, keeping below the upper limit mark.
• Disconnect everything, then turn the fuel cap vent lever and engine switch on.
• Start it. Close the choke from cold, pull lightly until you feel resistance, then pull briskly. Open the choke as it warms.
• Connect appliances once the engine has settled.
• When you finish, switch off, let it cool, then close the vent lever.

Delivery note: Honda generators can have a longer lead time than other brands. If you need one by a certain date, please contact us before ordering and we'll confirm availability.

Keeping it ready

Honda's warranty depends on servicing to this schedule by a Honda Authorised Dealer, using genuine parts, so keep every service receipt. If it will stand for months, follow the storage steps in the manual so the fuel doesn't go stale.

FAQs

Will it run a caravan air conditioning unit? Many units need a high start-up current that can exceed a single EU22i. Check your unit's start-up figure first, and consider a soft-start kit or two generators in parallel.

Can it charge a leisure battery? The 12V outlet is only for charging 12V car-type batteries and needs Honda's optional lead. Turn Eco Throttle off when using it. If you use AC at the same time, keep the AC load below 1.7kVA. You can also plug a mains battery charger into a 230V socket.

Can I run two together? Yes, with Honda's approved parallel kit, which isn't included. Keep the generators at least 1m apart, with their exhausts not facing each other.

Can I run it on a boat? Set it up on the bank, on firm, level ground and well clear of any cabin vent or opening. Exhaust gas is dangerous, so fit a working carbon monoxide alarm on board as well.

Why has the power cut out? The red overload light means it's overloaded or an appliance has a fault. Stop the engine, find the cause, then restart. A brief red light for up to about 4 seconds when a motor starts is normal.

Why did the engine stop by itself? Check the oil first. Oil Alert shuts the engine down if the level gets too low.

How does the warranty work? Honda UK gives generators 5 years for domestic use and 1 year for professional use. The machine must be registered for warranty by a Honda dealer and serviced to schedule. Neglected servicing, non-genuine parts, the wrong oil or fuel, stale fuel and use outside the owner's manual aren't covered. Please ask us about registration when you order.

Not sure it's the right size? Send us your appliance list at sales@generator-uk.co.uk or call 01744 520110, Monday to Friday, 8:30am to 5pm, and we'll help you size it.

Safety: run outdoors only, at least 1m from buildings and well away from doors, windows and vents. Never run it inside a caravan, boat cabin, awning or tent. Generator exhaust contains carbon monoxide. Let the engine cool before refuelling.
