Primus OmniLite Ti Multi-Fuel Stove Kit review

Scope note: This review covers the exact Primus US OmniLite Ti kit P321987 / UPC 7330033897463. It is a source-based assessment: I did not operate, weigh, test or photograph the stove in use. Its separately sold OmniLite Ti silencer is not included unless an exact offer adds it.

A compact multi-fuel kit with a titanium support structure

The P321987 package combines one burner with an ErgoPump fuel bottle, cleaning-needle multi-tool, multiple jets, foldable windscreen, heat reflector and pouch. The page highlights titanium pot supports and a design intended to work efficiently with Primus PrimeTech heat-exchanger cookware. The cookware itself is not listed as included, and the product page does not provide a general maximum cookware diameter. The burner can cook one pan at a time; its multi-fuel capability does not create a multi-burner layout.

As with OmniFuel, the value proposition is flexibility paired with deliberate setup, not a universal fuel adapter. The manual assigns separate jets: 0.36 mm for Primus disposable cartridge gas, 0.32 mm for white/stove gas and unleaded petrol, and 0.25 mm for kerosene or similar fuel. Those are OmniLite Ti model-family instructions, not values to transfer from OmniFuel. Primus' web copy also mentions diesel and aviation fuel, but those claims are not included in the matchable set without clearer fuel/jet permission in the exact manual. Verify the exact procedure for the fuel you intend to use; changing fuels requires more than turning the control knob.

Different from OmniFuel—and not independently tested

Primus positions OmniLite Ti as a lighter one-to-two-person option, with 2,600 W and a sub-four-minute liter boil when used with an efficient heat-exchanger pot. Its table separately lists three minutes and 185 g/h for a regular pot; the exact ID 3219 manual states about 2.3 kW and 130 g per hour at one bar. These manufacturer figures differ and have not been independently reconciled. The 341 g value has no stated minimum/bare/complete-kit basis. It should not be treated as a fueled pack weight, and it does not prove a strict manufacturer-listed minimum-weight requirement.

For the actual kit boundary, the US product page specifies the pump/bottle, tools, jets, screen, reflector and pouch, while saying gas is not included. Primus' listing says the stove is adapted to its heat-exchanger pots, but no evidence here supports a particular pot-size limit or independent fuel savings. Consider whether you will actually use its alternate liquid-fuel modes; if not, carrying the pump and spare jets may be unnecessary complexity compared with a canister-only burner.

Use the screen and silencer only within their limits

The kit includes a foldable windscreen and heat reflector. The manual recommends Primus' screen/reflector when the stove is not shielded from wind, while warning never to cover the stove or gas cartridge/liquid-fuel bottle. Keep the supplied screen in its intended orientation; do not enclose the fuel, substitute a makeshift shield or operate indoors, in a tent or in a vehicle. The exact manual requires at least 1,250 mm clearance from the stove to the ceiling and nearest wall, outdoor use, stable placement, proper hose routing and full priming for liquid fuel. It warns against relighting a hot appliance and calls for keeping the hose and bottle away from hot surfaces.

The OmniLite Ti Silencer is a separate accessory. Primus says it is suitable with LP gas or white gas but not diesel, kerosene/paraffin or aviation fuel. It is not in this kit's contents and should not be paired with every fuel mode merely because the burner is multi-fuel. A quieter accessory therefore adds another compatibility boundary rather than making the complete stove universally interchangeable.

Who may value this exact kit

Compare P321987 if you want a one-burner expedition kit with titanium supports and intend to use its distinct, documented gas/white-gas/petrol/kerosene jet plans. It is less suitable for a shopper seeking a simple canister burner, a documented maximum pot width, a verified minimum carried weight or permission to use any fuel named in marketing. Match the exact kit number, check the included parts and manual edition, and follow the fuel-specific jet and clearance instructions. The review makes no claim of personal use, price, current inventory or measured boil performance.
