Jetboil MightyMo



Our Rating:

At a glance
: Fine flame control, pressure-regulator, solid construction.
Minuses: Expensive, works best with Jetboil’s pots and pans.

Features: A pressure-regulated stove offering consistent output for the life of the canister. It weighs 95g, uses push-button Piezo ignition and has semi-serrated pot supports designed to work with Jetboil’s Fluxring range of pots and pans which provide greater efficiency and wind protection. The flame adjuster requires four full turns to reach maximum output, allowing micro fine-tuning of flame size. 

Construction: Stainless steel with durable pot supports that don’t bend or twist with hand pressure. One potential weakness is the exposed electrode – a thin wire sticking out above the burner head. I suspect this exposed position contributed to the Piezo ignition usually requiring more than one press to ignite the flame. 

Power: The stove pumps out 10,000BTU, making it the least powerful stove tested and suggestive of why it took longer in the boil tests. It’s performance is said to improve by using Jetboil’s Fluxring pots and pans. The flame adjuster allowed fine-tuning of the output and flame size to the nth degree.

In use: The stove’s pot supports are big enough to accommodate large-diameter pots and pans. However, these didn’t seem to grip my cookware, which moved while stirring foods.

Lighting the stove always required more than one press of the Piezo because the handle needs to be turned an extra turn or two to get enough gas flowing. The Piezo button is placed at an angle to the flame adjuster, making it easy to press while controlling the gas.

The sea level and altitude tests results were identical, with both taking 2min10sec to boil 500ml of water.

Even though it doesn’t have a wind-blocking ledge around the burner head, the stove did not seem to be overly affected by wind gusts.

The large, glove-friendly flame adjuster was a real asset during the risotto test, and allowed me to control the flame to a much greater degree than I am used to. 

Value: The stove seems expensive, especially when taking into account it works best with Jetboil’s own pots and pans. 

Verdict: For fine-tuned cooking where absolute control over the flame is required, you can’t do better.

Where and how the stoves were used

This stove, the MSR Pocket Rocket Deluxe and Soto Amicus were all tested under the same conditions and for doing the same tasks. They were used to boil water at sea level and at 1000m altitude in Tongariro National Park in temperatures ranging from 13℃ to 19℃. The stoves were also used to cook a risotto meal which required 20 minutes of continuous cooking time.
