Dear Santa,

It's 8500 btu

The Primus Micron Ti Stove uses ALL Lindal valve (screw-on) type, compressed gas, fuel canisters made by @ least nine manufacturers including Brunton, Coleman, Jetboil, Kovea, Markill, MSR, Optimus, Primus, Snow Peak, etc. These canisters can be found in the US, Canada, Australia, New Zealand, western Europe, Japan, & Korea.

Absolutely. The Micron is compatible with any canister that has a Lindal valve. The most common are MSR, Brunton, Snow Peak, Primus, and Jetboil.

This is not refillable, but the advantage is that the fuel is light and burns hot, so you can bring less. If you want a refillable stove, the MSR Simmerlite and Whisperlite are classic choices. Solid, dependable (my dad's been using the same Whisperlite for 35 years), they're immensely popular and it's because you can run them forever and fix them with a stick. They're not the lightest stove out there (that'd be the Coleman Fyrestorm), but the Fyrestorm doesn't have the reputation or the simplicity and really, the Simmerlite's only another ounce. That'd be my vote.

The Micron TI fits into a Snow Peak 600 cup along with an inverted 110 gram size canister, mini lighter, wash cloth, & a modified folding spork. This all weighs 400 grams & will nest in most other cook sets.

The Primus Micron Ti Stove uses ONLY & ALL Lindal valve (screw-on) type, compressed gas, fuel canisters made by @ least nine manufacturers including Brunton, Coleman, Jetboil, Kovea, Markill, MSR, Optimus, Primus, Snow Peak, etc. These canisters can be found in the US, Canada, Australia, New Zealand, western Europe, Japan, & Korea. It also can not use kerosene, white gas, or any other liquid fuel.

If I understand your question correctly, the diameter of the burner head/cooking area is about the size of a quarter. The ports/holes are positioned so they form flames that cover an area the size of a golf ball, spreading out when a pot or pan is sitting on the pot supports.
