This version of the Champion 92120i “The Mighty Atom” can only run at 110 Volts. It has all the main features of the 230V version but is designed for site work. One of the main benefits of the Champion 92120i is the noise level just 58 dBA at 7 metres, which is very quiet compared to most 110V site generators. Being a compact suitcase generator the 92120i also is very light, just 17.6 kg making this a very desirable portable petrol generator.

Power Rating of the Champion 92120i

  • 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)

Is the Champion 92120i Easy to Start and Use?

The Champion 148F-D 79CC 4-stroke OHV engine produces the 2.2KW of power for your work tools when you are on site or home workshop use. It has an easy recoil start (pull start) and an Eco mode for fuel efficiency. Furthermore, the Champion 92120i uses cold start technology to ensure quick starting on freezing winters mornings.

You can connect other Champion inverter generators to the .92120i Mighty Atom 110V with the optional Parallel Kit.

The unit comes with 1 x 110V 13A sockets and 1 x 12V output fitted to the Champion 92120i to connect your electrical equipment up to.

Low Noise Levels

You might think having a petrol generator will be very noisy. Well think again; the Champion 92120i is ultra-quiet at 58 dBA at 7 metres.

What Happens If I Do Not Use My Champion 92120i 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.

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.
