Two of the most iconic backpacking stoves ever made — and they couldn't be more different in philosophy. The Jetboil integrates pot and stove into a single system optimized for boiling water fast. The MSR Pocket Rocket is a tiny, lightweight burner that works with any pot. We tested both head-to-head so you don't have to guess.

Boil Time Test Results
In our tests at 65°F with no wind, the Jetboil Flash boiled 500mL in 2 min 20 sec — significantly faster than the Pocket Rocket 2's 3 min 10 sec with the same volume. In windy conditions (15 mph), the Jetboil's integrated windscreen gave it a bigger advantage, while the Pocket Rocket slowed considerably without a separate windscreen.
Weight & Packability
The MSR Pocket Rocket 2 weighs just 2.6 oz and packs to the size of a golf ball. The Jetboil Flash system (stove + 1L cup) weighs 13.1 oz — but it replaces both your stove and cooking pot. If you're already carrying a cooking pot, the Pocket Rocket adds almost no weight. If you're buying both a stove and pot, the Jetboil can actually be lighter overall.
Real Cooking Performance
The Pocket Rocket wins for actual cooking — its excellent simmer control lets you sauté onions, simmer a sauce, or fry an egg. The Jetboil Flash is fundamentally a water boiler: great for rehydrating freeze-dried meals or making coffee, but frustrating for anything requiring heat control.
Our Verdict: Which Should You Buy?
Choose the Jetboil Flash if: you primarily boil water for dehydrated meals or hot drinks, you want the fastest setup and boil time, or you camp in windy conditions frequently.
Choose the MSR Pocket Rocket 2 if: you want to do real camp cooking with multiple pots and pans, you're gram-counting, you're on a tight budget, or you camp in cold weather (the Pocket Rocket 2 has a pressure regulator for better cold-weather performance).
