Compare the POM MK3 and POM Runner on power, capacity, and carry style. Find out which model delivers the strongest defense for your daily routine.
Quick answer
Both the POM MK3 and POM Runner share the same powerful POMClear formulation (1.4% major capsaicinoids, 10% OC, 2M SHU) and identical burst capacity. The real difference is in the carry design: the MK3 is a pocket-friendly keychain model, while the Runner is optimized for clip-on waistband or bag carry. Choose the one that fits how you actually carry your spray every day.
Power and performance: identical core specs
Both the POM MK3 and POM Runner use the same ½ fluid ounce canister with up to 20 half-second bursts or 10 seconds of continuous spray. The stream pattern reaches up to 12 feet, and the POMClear formulation delivers 2 million Scoville heat units with 1.4% major capsaicinoids. In terms of stopping power, there is no difference between the two models.
Carry style and everyday accessibility
The POM MK3 is designed as a compact keychain unit, making it easy to attach to your keys or a small carabiner. The POM Runner, on the other hand, features a low-profile clip that attaches securely to waistbands, pockets, or the inside of a bag. If you prefer not to have your spray dangling from your keys, the Runner's clip design keeps it discreet and instantly accessible.
Trade-offs to consider
- Identical stopping power: Both models use the exact same POMClear formulation with 2M SHU, 1.4% MC, and a 12-foot stream. Neither is more powerful than the other. Your choice comes down to carry preference, not power.
- Keychain convenience vs. clip security: The MK3 attaches to your keyring for quick access but can swing or get tangled. The Runner's clip stays flat against your waistband or bag, reducing bulk and keeping the spray in a fixed position. If you carry keys separately, the Runner may be more reliable for draw speed.
- Same capacity, different profile: Both hold ½ fluid ounce and offer 20 bursts. The Runner's clip adds a slightly different shape, but the canister dimensions are identical. Neither model sacrifices capacity for its carry style.
