At the heart of “The Mighty Atom” is the super economical and reliable Champion 4-Stroke 79cc Euro V Emission Standard engine, which lets you enjoy a quiet 58 dBA at 7 metres for up to 10.5 hours of run time at 25% load (Eco Mode) and helps it produce 2.375 KVA / 1.9 KW of power effortlessly.

Getting the power where you need it has been made easy. At just 17.6kg the Champion 92001i is the world’s lightest 2.2kW inverter generator. (At time of launch July 2020. Weight excludes fuel)

Power Rating of the Champion 92001i

  • 2500 STARTING WATTS (Short bursts of output for approx. 6 seconds ONLY in order to fire up motor driven equipment)
  • 2200 MAXIMUM WATTS (The absolute MAXIMUM output that your Generator will give you for about 5 minutes tops, before tripping)
  • 1900 RUNNING WATTS (The all-important CONTINUOUS Rated power that your Generator will comfortably run at to provide power to your chosen equipment, also this is the most relevant value to compare against other models)

Using Sensitive Equipment with The Electrical Power from The Champion 92001i – The Mighty Atom

True Sine Wave inverter technology makes The Mighty Atom ideal for sensitive electronics such as computers, laptops and TV. This makes the Champion 92001i perfect for your next camping trip or for powering small household items like fridges/freezers, power tools, lighting units & garden equipment.

Is the Champion 92001i Easy to Start and Use?

You bet it is – Champion’s new EZ Start Dial removes all the confusion of starting the generators engine. The Champion 92001i has an easy read LED light display. This shows maintenance, low oil and receptacle status indicators. This is important as you will need to know when your generator will need servicing after the scheduled hours run time has been reached, this will help keep your generator maintained and running for thousands of hours use.

You can connect other Champion inverter generators to the Mighty Atom with the optional Parallel Kit.

The unit comes with 2 x 230V 13A sockets and 1 x 12V output fitted to the Champion 92001i to connect your electrical equipment up to.

What Happens If I Do Not Use My Champion 92001i For Long Periods?

If you are planning to store your generator for a long period its ‘best practice’ to either drain the fuel tank then run the generator until it stops. This will prevent any unused fuel congealing and clogging the carburettor. Or to stop the fuel from going off use a petrol additive. Remember, stale fuel can stop your generator from starting when you need it.

Low Noise Levels

You might think having a petrol generator will be very noisy. Well think again; the Champion 92001i is ultra-quiet at 58 dBA at 7 metres.

When will I receive my order?

In most cases, a product on our website will give you an indication of the current stock availability, but shipping is not uniform for all products. We maintain fantastic relationships with all of our suppliers and we aim to get products to customers within 3 business days of the order being taken. This availability is based on information from our suppliers and from sales and supply patterns. The availability information given is a guide only and not a guarantee as there are external factors that we may not have control over.

Coronavirus Update – UK couriers and transport companies will not currently guarantee delivery times and we are seeing a slight delay in deliveries – please bear this in mind when ordering.

Specialist Couriers – Some items such as the larger portable power stations are sent by specialist courier as standard couriers will not accept them. These specialist couriers are very reliable but sometimes don’t have tracking or timed delivery.

Split deliveries – We sometimes need to send orders for more than one item by different courier networks (portable power stations for example) – so you may receive items at different times.

1500rpm machines or larger diesel gensets however are typically priced on application and all depend on the destination. We will be happy to quote on any large diesel generator and discuss your needs over the phone or via email.

Most orders placed before 12pm on a business day will be shipped from our suppliers on the same day provided the product is in stock. If you need to be certain an item is in stock and available, or if you need a lead time, it’s worth calling our sales team on 01329 722390. Pricing for extended shipping areas like Northern Ireland, the Scottish Highlands and outlying Islands, Outer Hebrides, Channel Islands, Isle of Man, Scilly Isles, and other postcodes not considered as UK mainland can be obtained also by calling our offices.

Please note that the processing of a payment and acknowledgement email does not constitute a legally binding contact. In the case of mispricing, changes in stock quantity, or if we believe the machine will be misused, we reserve the right to cancel the order and provide a full refund.

Heavy Items

You will be contacted by phone after ordering a larger item to confirm a delivery date before your order is dispatched. Large or heavy items are dispatched through a pallet network, so if we can’t get in contact with you, we may be unable to send out your item on a next day delivery. Please be sure to include a working phone number with your order.

Heavy items will require the recipient to make arrangements to take delivery of the goods and may require the recipient to help the courier unload the item. For items that are delivered on a pallet the courier will leave the pallet as close to your door as possible.

1500rpm diesel generators will require forklift (or similar) offloading; if this is not available then we can arrange a Hiab offload at an additional price – please call us to discuss any delivery requirements.


5 reviews for Champion 92001i 2200W The Mighty Atom Petrol Inverter Generator

  1. Mike Bartlett (verified owner)

    I bought this generator for the track, mainly for a pair of tyre warmers but knowing it could run other things too. It’s brilliant!, powers the warmers lovely, is very quiet, seems economical on fuel and is easy to start. Only think lacking is a fuel gauge but apart from that it’s perfect for the track. I think it would just run two pairs of warmers depending on your wattage (mine are 1000w per pair.)

  2. John Cutland (verified owner)

    This is a ‘hope-I-don’t-need-it’ purchase. The danger of losing a fridge and two freezers full of food in a power ‘outage’ is something I don’t want to face. We had a break in supply 2 years ago and I think that this generator is more than enough to give peace of mind. The spec looks good, the sound level is really acceptable and fuel economy looks good. The price and service, with very efficient delivery, from Hampshire Generators made it a sensible buy. If we don’t need it because of a power cut the occasional remote caravan holiday will see it used.

    Cracking bit of kit for the money. well made, well specced, quiet. Champion are an American company and have been around a long time, there are plenty of positive online reviews of this and their other products. Based on this and much reasearch I purchased a 92001i. I was not dissapointed when it arrived. followed the very comprehensive manual and it started on 4th pull from dry. Euro 5 compliant so it will run on E10, 1st service is oil change after 5 hours use, after that annual or as conditions require. Champion uk are reputed to be very supportive of their customers and dealer network, my own experience does not contradict this. This was a factor in decision to purchase. Hamphshire Generators, as suppliers, provided fast delivery, ist rate advice, all round exceptional service and are one of those rare uk businesses that still have time for their customers.

  4. Mark Weston (verified owner)

    I bought my generator it arrived the morning after I ordered it, the delivery was unbelievably quick , I spent a couple of days checking and double checking the instructions just to be sure I didn’t make any mistakes, on filling up with oil and fuel it started on the second pull of the starter cord, if you are looking for a small easily transportable generator this inverter generator is the one to go for.

  5. Bob Tongs

    Picked this up today from Hampshire Generators, staff very helpful, and friendly.
    This is a well built bit of kit, easy to set up and started on 1st pull, can’t do better than that. 1st service is after 5 hours run time, just a case of tilting generator to drain and then refill, everything very accessible. Put fuel in the tank and started without effort. Run for an hour or so, have had lights, freezer, power tools, camping kettle all working at the same time. Tried my quick boil kettle on its own, but blew the trip but at least I know my lower powered one works for a cuppa. The microwave works but as suspected it won’t run the oven part. The generator is not heavy and controls are easy to understand. The eco mode is quite a fuel saver when there is a light load. I haven’t tried out the 12 volt output yet but comes with a useful lead and clips for battery charging, and a double usb output adapter, but it can’t be used the same time as the 240 volt outlet according to the manual, which is a little annoying. Most similar generators on the market have an running output of 1600 watts but the extra 300 watts makes all the difference. As stated by another, a fuel gauge would have finished it off nicely but not difficult to remove the cap and peer in to the tank! All said and done this is a very useful generator, quiet, easy to store and hopefully years of life in it. This is the one to go for.
