PRIMUS P-156S Ultra Spider Stove III — Separated Single Burner for Outdoor Use

Ultra-lightweight outdoor burner for backpackers

The PRIMUS P-156S Ultra Spider Stove III offers a compact solution for on-the-go cooking. Weighing just 192 g, this separated single burner brings dependable flame control to tents, shelters, and campsite tables without weighing you down. Its minimal footprint makes it easy to stash in a daypack, while the metal construction promises durability in diverse environments.

Key design and performance features

• Weight: 192 g
• Output: 3.5 kW (3000 kcal/h)
• Maximum pot diameter: 6.7 in / 17 cm

The stove uses a 4-blade trivet that includes an extension rod and is set in an X-shaped arrangement to double the windshield. This thoughtful geometry helps shield the flame from side gusts and contributes to steadier simmering and faster boiling, especially when weather turns breezy. The burner legs fold into the assembly for a cohesive, compact profile, making setup simple on rocky ground or grassy patches.

Wind resistance, stability, and efficiency

Pre-heat pipes guide gas vaporization through combustion heat, which helps promote consistent flame behavior as you start a cook or adjust flame height. The integrated legs and the wind-shielding X-shape work together to reduce heat loss, so you can boil water or keep a small pot at a steady simmer more reliably in outdoor conditions. While not a guarantee of performance in every environment, these design choices contribute to a more predictable cooking experience when you’re away from home.

What you can expect in real-world use

• Quick setups at campsites or trailheads thanks to a compact, single-burner form factor.
• Reliable heat for boiling water, rehydrating meals, or simmering sauces in a small cooking pot.
• Stable cooking when paired with appropriately sized cookware up to 6.7 inches in diameter.

For campers seeking a lightweight, dependable burner that minimizes bulk without sacrificing essential features, the P-156S offers a balanced blend of portability and performance. Consider it for minimalist camping kits, weekend hikes, or any outdoor cooking scenario where every gram counts and reliability matters.
