Optimus Polaris Optifuel incl. 0.4L Fuel Bottle review

Research-based review · exact US-locale model page: SKU 8019408

The important difference in this Polaris package is the included 0.4 L Optimus fuel bottle, not a new burner mechanism. Katadyn’s US-locale page identifies item 8019408 and EAN 7612013194084 by the exact name “Optimus Polaris Optifuel incl. 0.4L Fuel Bottle.” Its action is “Inquire,” not a normal retail checkout, and the captured page does not provide a complete box checklist or a total package weight. Treat the bottle as the model-specific inclusion; verify the rest of a seller’s package before relying on it.

What the bottle bundle changes

The Polaris burner can use either an Optimus threaded EN 417 canister or a pumped liquid-fuel arrangement, but the latter needs a fuel bottle. This exact SKU makes a 0.4 L bottle part of the named package. The manufacturer’s main image associated with the 8019408 page shows the Polaris connected to an Optimus bottle; it helps identify the package, but it does not prove every other accessory in a box.

Compared with the standalone 8019229 product, the practical attraction is having the named bottle together with the burner instead of sourcing it separately. That matters if you specifically plan to cook with the manual’s liquid fuels. If you expect to use canister gas only, a liquid-fuel bottle adds carried bulk without changing the gas connection or cooking position. The package page does not say whether the pump, screen, heat reflector, tool or bag are included; confirm exact item number and contents with the seller. Liquid operation requires the correct pump as well as the bottle.

Do not treat 0.4 L as a fill instruction

The 0.4 L is the package’s nominal bottle description, not a safe-fill volume or an instruction to pour in 400 ml. The Polaris manual says not to fill to the top and directs the user to stop at the maximum line marked on the bottle so there is room for the pump and pressurizing air. The exact product page does not state the numeric volume at that line. Use the marked limit on the actual bottle and the instructions supplied with it.

For liquid use, the manual names white gas, gasoline, kerosene, diesel and jet fuel, requires an Optimus bottle, and instructs the user to pressure, prime and leak-check the system. It forbids mixing fuels. For canister use, it calls for an Optimus threaded EN 417 cartridge up to 450 g; the manufacturer sources do not establish that this is the exact MSR 80/20 or Jetboil JetPower blend. Similar threads do not prove that a brand-specific fuel requirement is met.

Same burner rules, with more to carry

The exact 8019408 page links the same Polaris English manual used for the 8019229 burner. That manual describes one adjustable burner, upright canister vapor feed for the best simmering control, and an inverted canister mode only after a 30-second upright start. It also explains that liquid-fuel operation needs the pump and a separate bottle. Because the product page and exact image identify the same Polaris burner body, the 330 g manufacturer minimum without pump is useful as a burner-only figure; it is not the weight of the bottle bundle. The shared manual lists 475 g for the stove with pump, and the extra bottle, fuel, cookware and other equipment raise the actual carry load. No complete package mass is available.

The manual limits cookware to 220 mm (8.5 inches) and 4 kg combined pan plus food. It permits the Optimus windscreen arrangement with a 25 mm gap between pot and screen; keep the canister or fuel bottle outside the screen and add the screen only after lighting. The 0.4 L bundle page does not publish a separate screen or pot specification, so these are the shared burner-manual limits, not evidence that the pictured assembly includes every accessory.

Read the output figures cautiously

The exact bundle page displays a generic 4,200 W value and an approximate three-to-four-minute boil time without separating a gas mode from a liquid mode. The Polaris manual identifies 3,300 W for canister gas and 4,200 W for white gas, while the manufacturer’s fact sheet for the same 8019229 burner body lists a different gas figure. Those sources conflict on canister output; this assessment does not pick a favorite number or rank the stove by wattage. Published boil and burn times are conditional manufacturer estimates, not measured results.

Who should choose this package?

Choose 8019408 over the standalone Polaris only if the named bottle solves a real liquid-fuel packing need and the seller confirms the pump and other required equipment. It remains a single-burner system with a sizable carry load and careful handling steps, not a light shortcut. If you only need gas, compare the standard 8019229 package instead and check whether a bottle is actually included. The captured US-locale manufacturer page is inquiry-only; no live price, stock or exact Amazon listing is claimed. This is research-based, not hands-on testing.
