WiKa UltraLight spirit burner review

An aluminium alcohol burner with a carbon felt insert, and the only stove in this hub that takes no gas canister at all. It states an output and a weight — and gives two different weights for the same burner.

The bottom line The odd one out in this hub, and the honest one about its own figures — until you notice it publishes two of them for the same weight.

What this listing puts on record

An aluminium burner cup with a high-temperature carbon felt insert, sold on its own. There is no pot support, no windshield and no canister: it is the burner and nothing else.

The fuel decides the rest

The maker names ethanol, alcohol, spirit and alcohol-based burning liquids. That is a different supply problem from every other stove here — no valve standard to match, no cartridge to find in a village shop, and no half-empty canister to carry home. It is also a different flame: alcohol burns invisibly in daylight, and the maker gives no boil time to set against the gas stoves.

What the felt is for

Two claims, both stated. It holds the fuel, so a knocked burner does not empty itself. And it is stated to light at sub-zero temperatures immediately, with no wait for the burner to reach full output — which is the failure mode of gas as a canister cools.

What the listing keeps quiet about

No boil time, no water volume, no packed size. And the weight is published twice at two different values: 23 g in the title, about 25 g in the maker’s own bullet.

Before ordering

Work out what it sits in. The maker names its own FlexFire, StormFire and LightFire bodies and a separate FlexCook pot stand; it also says other makers’ systems will take it, without naming them. Follow the maker’s instructions on filling, lighting, extinguishing and where the burner may be used, and the rules of the site you are on.

What it does well, and where it gives way

Strengths

  • Publishes an output figure, which most of the gas stoves in this hub do and most alcohol burners do not
  • The carbon felt is stated to hold the fuel against spillage and to light in sub-zero temperatures without waiting for the burner to come up to power
  • An EPDM lid seal is named, stated to be alcohol-resistant and to contain fuel and smell if the burner is closed before it has burned out
  • Names the stoves and the pot stand it is built to sit in, so what else you have to buy is known before ordering

Compromises

  • Two different weights for the same burner: 23 g in the title, about 25 g in the maker’s own bullet
  • No boil time and no water volume, so the 1,200 W figure cannot be turned into minutes on any published basis
  • Nothing to cook on is included — no pot support and no windshield, and the maker sells the stand separately
  • No packed size, which on a burner meant to live inside a pot is the measurement that decides whether it does

What people ask before buying

Does an alcohol burner need a canister fitting?

No. It is filled with liquid fuel and lit directly, which is why the canister fitting line on this stove reads as not stated rather than as a thread size. That also means none of the gas cartridge standards named elsewhere in this hub — the Lindal screw thread, the MSF-1a bayonet, the Campingaz CP250 — apply to it.

What does the 1,200 W figure tell you?

It is the burner output the maker publishes, and it is a real number. What it is not is a boil time: without the water volume and the minutes beside it, no stove in this hub can be turned into a time at the stove. Read the maker’s instructions for filling, lighting, extinguishing and where the burner may be used.
