Optimus Polaris Optifuel review

Research-based review · exact model: SKU 8019229

The Polaris Optifuel stands apart from the light top-mounted stoves elsewhere in this library because it can run either from a threaded gas cartridge or a pumped liquid-fuel bottle. That makes it a plausible choice when the ability to change fuel systems matters more than compact carry weight. It is not a quick, featherweight burner: the manufacturer lists 330 g without the pump and 475 g with it, before fuel, cookware or other gear.

One burner, three documented ways to feed it

The English manual describes upright vapor-feed use with an Optimus EN 417 cartridge, an inverted-canister liquid-feed mode, and a pump-and-bottle arrangement for named liquid fuels. In ordinary gas use the manual recommends the upright setting for simmering. For colder conditions, low canister pressure or a faster boil, it describes an inverted mode—but only after starting upright and letting the stove burn for 30 seconds. The manual also warns about flare-ups when switching and about fuel leaks in freezing temperatures; the O-rings can stiffen. These are procedures to study before a trip, not modes to improvise from a product photo.

The liquid-fuel path is different work. It needs the pump, an Optimus bottle, pressure, priming and careful leak checks. The manual names white gas, gasoline, kerosene, diesel and jet fuel, limits liquid use to petroleum-based fuels and says not to mix fuels. It does not authorize alcohol fuel or arbitrary adapters. The standard 8019229 fact sheet lists the pump and maintenance items but not a fuel bottle. Do not assume the separately named 8019408 package or another bottle is included with this SKU.

For canister mode, the manufacturer specifies Optimus threaded EN 417 cartridges up to 450 g. Although the connection is threaded, the available Polaris sources do not establish the exact MSR 80/20 or Jetboil JetPower blend. The finder therefore does not count this as either branded fuel system.

Cookware and windscreen rules matter

The exact manual caps cookware at 220 mm (printed as 8.5 inches) and the combined pan-plus-food load at 4 kg. This is a maker limit, not a guarantee that every pan base, handle or full pot will clear the hose, support legs and ground. The manufacturer-recommended Optimus windscreen may be used, but fit the screen to the pot with a 25 mm (1-inch) gap for airflow; keep the canister or fuel bottle outside its perimeter; and place the screen carefully only after lighting. The manual prohibits non-Optimus windscreens and heat reflectors. A larger pan, enclosed fuel container or improvised screen is not an acceptable shortcut to the advertised multi-fuel flexibility.

What the weight and performance numbers do—and do not—say

The 330 g minimum is specifically the stove without its pump; the manufacturer lists 475 g with the pump. Liquid-fuel use depends on that pump, while the fuel bottle, liquid fuel and cookware add further carried weight. A full package weight is not stated. Even at its bare-stove figure, this model exceeds the finder’s 300 g maximum, so it is absent from every hard carry-cap match.

Published gas output is not consistent across the manufacturer’s own sources: the US product page gives 4,200 W without naming a mode, the English manual lists 3,300 W for canister gas, and the fact sheet lists 5,300 W for gas. Both the manual and fact sheet list 4,200 W for white gas/liquid fuel. Because those canister numbers conflict, this review does not choose one or use it as a performance ranking. The fact sheet estimates about four minutes per liter on gas and 3.4 minutes on liquid fuel, depending on conditions, and up to 105 minutes from a 230 g cartridge or 100 minutes from 400 ml of liquid fuel at full output. Those are manufacturer claims, not independent boil tests. The valve is adjustable, but no hands-on test here establishes how steadily it holds a low simmer.

The integrated magnetic cleaning needle and included multitool give the owner service tasks to learn; they are not a substitute for the manual’s fuel, pressure and preheating checks. This configuration has no documented push-button piezo igniter, so a separate lighting tool is required.

Who may find the tradeoff worthwhile

Consider this model only if its two fuel systems solve a real resupply or cold-weather problem and you are willing to carry and maintain the pump-equipped setup. A lighter canister-only stove may make more sense for routine short trips; the Polaris’s documented strength is the option to move between a specific canister mode and a specific pumped-fuel mode. That flexibility comes with fuel-specific handling, a 220 mm cookware ceiling and significant carry mass.

This is a source-based assessment, not a hands-on review. The exact US-locale manufacturer page identifies SKU 8019229 but offers an inquiry action; no price, retailer stock or current availability is claimed. Manufacturer output sources disagree, and all boil and burn times above are their own conditional estimates. Check the exact package, included equipment, fuel and current safety instructions before purchase or use.
