Primus Lite Ultra XL P356045 with visibly larger 1.2 L pot and separate burner assembly.

A useful fit for

A one-burner walk-in system for someone wanting a somewhat larger 1.2 L matched pot while keeping the burner, heat exchanger, lid and storage system nested together.

The main tradeoff

The 290 g figure is burner plus pot, not a minimum fueled load; the maximum alternate-pot diameter is unknown, the manual forbids wind shields and its capacity text identifies the 0.8 L sibling rather than P356045's 1.2 L pot.

Your needs, this model

Does it fit your priorities?

Does the XL's 1.2 L name establish how much water is safe to boil?

No. The exact product page identifies a 1.2 L pot, but the page-linked 3560 manual names a 0.8 L pot and limits water to 0.5 L. That capacity-specific limit cannot safely be transferred or scaled to the P356045 XL; check its shipped instructions before planning a fill amount.

Can I meet a separate-windscreen requirement with P356045?

No. The exact product page links a 3560 manual that says not to cover the stove or cartridge with a wind shield, rock or similar object. Its pot-capacity wording does not identify the XL size, so follow the exact unit's supplied manual; no extra-screen approval is asserted.

Is its 290 g burner-plus-pot weight the same as a minimum carried weight?

No. Primus labels 290 g as burner plus pot; the separate 2206 cartridge is not included, and the page does not identify a strict minimum-weight or full package measurement. The maximum alternate cookware diameter is not documented either.

The Lite Ultra XL Stove System 1.2 L (P356045) enlarges Primus’s integrated one-burner format, adding a larger matched pot while keeping the burner, lid and cooking system together. The exact US page identifies the SKU but shows no UPC. Primus describes it for quick meals and one-pot cooking for up to three people; that is a maker-use description, not a tested serving count. This review relies on manufacturer materials, not personal ownership, use, weighing or cooking trials.

The XL difference is capacity, not another burner

The US listing describes a hard-anodized 1.2 L pot with integrated heat exchanger, low-profile lid, titanium handles, piezo ignition, pot supports for other cookware and a fabric storage bag. Fuel is not included. One burner still means one active cooking position, so “XL” does not imply that two dishes can be heated at once. The larger pot can expand a one-pot menu, but the product pages do not make its 1–3-person label a meal-size guarantee.

The listed product weight is 290 g for burner plus pot. The smaller P356044 page lists 240 g for burner plus pot, a 50 g arithmetic difference between the two maker figures. This is not our measured difference between complete packages: neither page describes the number as the strict minimum-weight field in this finder, and the separate fuel canister remains outside the figure. The distinction matters to anyone comparing a product-card number with the load that will actually go in a pack.

A manual link with a capacity mismatch

The exact P356045 manufacturer page links the Primus 3560 Lite Ultra manual. That is the source that makes its safety guidance relevant; however, the PDF text identifies the accompanying 0.8 L pot and tells users to fill it with no more than 0.5 L water. P356045 is the 1.2 L XL. I am not transferring that 0.8 L pot limit to this larger version, scaling it up or inventing another fill limit. Check the instructions supplied with the specific XL unit, and ask Primus for confirmation before relying on a capacity-specific cooking boundary. The product identity itself is clear in the exact P356045 US product page, while this documentation mismatch remains an explicit limitation.

For the same reason, the 1.2 L value is not an answer to maximum alternate-pot diameter. The product page mentions supplied supports for other pans but gives no maximum vessel width. A support ring’s visible size, the 1.2 L pot capacity and the outer dimensions of the product are not valid substitutes for a manual-approved cookware ceiling.

Fuel, flame and wind protection

The manual linked by the exact P356045 page specifies the Primus 2206 propane/isobutane/butane cartridge and says not to cover the stove or cartridge with a wind shield, rock or similar. It also describes adjusting the flame with the burner valve. These are documented fuel and control statements, not evidence that a low flame has been independently tested for stable simmering. The precise cartridge blend is not the MSR 80/20 or Jetboil JetPower option in the finder; fuel is not supplied.

Although the PDF names the 0.8 L pot, its basic directions also require outdoor use and upright, stable placement, and it warns against covering the stove or cartridge. Because the document is linked from P356045 but has text that does not match the XL pot, use the manual delivered with the exact unit for capacity-specific directions rather than assuming the PDF is perfectly version-matched. No separate-screen permission is claimed; the linked manual's warning is the opposite of permission to add an external shield.

Who should compare it?

The XL can suit a hiker who wants a more capacious single-pot system than the 0.8 L Lite Ultra, but still wants the burner and heat-exchanger pot nested together. It is a different use from the PrimeTech multi-pot systems: those use a remote burner with two pots, integrated screen and gripper, whereas Lite Ultra keeps a single small pot attached over a top-mounted burner. None of those package layouts should be collapsed simply because each has one heat source.

Before ordering, confirm P356045, the 1.2 L pot and supplied support pieces, the proper Primus 2206 cartridge, and the manual present in the box. If the purchase hinges on a verified maximum fill, alternate-pot diameter, published minimum carry weight, separate windscreen permission or low-simmer test, the reviewed materials do not supply all of that. The compact manufacturer photograph and listed mass are references, not a personal review or proof of field performance.
