The lowdown

The first thing that struck us about the Onja stove was the design. It’s so sleek and hip looking, I didn’t know if I wanted to just sit and stare at it, or actually cook on it.

Open the straps, and remove the thick oak chopping board to start cooking on the Onja. Pull the legs apart to create a wide, stable cooking surface, then turn it onto one side to screw in your gas canster underneath (you will need 2 if you want to cook on both burners).

The smallest 100g gas canister available for the Onja is shown in the picture above, and costs around £3.50; available from outdoors shops like Go Outdoors and Decathlon. We’ve been told that this kind of gas will operate at a lower temperature from the long, thin aerosol gas canisters we’ve used in the past.

The gas is easy to attach with the screw in threads, and once secure, you’re ready to start cooking. We only had a small lighter with us, so lighting the stove did require some pretty quick reflexes; we’d recommend using long matches or a long lighter designed for starting BBQs and fires.

Thanks to the design, once in use, the burners are partially shielded from the wind, and we found that our breakfast bacon and eggs cooked pretty quickly outdoors on a fairly windy morning, with the stove in an exposed area on top of a table.

The verdict

The Primus Onja stove is beautifully designed and quite unlike any camping stove we’ve come across so far. It’s simple and intuitive to use and highly portable too, which makes it ideal for camping, picnics and days out at the beach. It’s smaller than some other double burner stoves we’ve seen which makes it a practical choice, especially if you are limited on space.

Our only gripe was with the cooking surface. We used our usual camping pan and a large based frying pan on the stove, and whilst both fitted despite being larger than typical camping-specific pans, I did find that the frying pan had a tendency to slide on the surface slightly. 

This meant that when stirring or turning food over, it was necessary to keep one hand on the handle, to hold it steady and stop it toppling off.

  • The lack of auto-ignition may put some off
