While I briefly mentioned the Primus EtaPower MF (multi-fuel) backpacking stove on Day 3 of OR, here's some more information about it and the new integrated canister EtaExpress for all the stove gearheads.

Primus EtaPower MF

Primus EtaPower MF

Unlike many stoves that call themselves “multi” or “all-fuel,” but really only burn liquid fuels, the EtaPower MF is an actual multi-fuel backpacking stove that will burn any available fuel—butane, propane, diesel, paraffin, or aviation fuel. According to Primus, the EtaPower MF “blends the most fuel-efficient stove design in the world with the convenience of omnivorous multi-fuel technology.” Primus claims its ETA burner design is twice as efficient as average stoves, allowing for faster boiling times, less fuel consumption, a lower total weight, and a more environmentally friendly stove.

The EtaPower MF has a piezo ignitor and comes with a burner stand, windscreen, 2.1 liter EtaPower pot with heat exchanger, and .35 L fuel bottle that nests inside; additional accessories include a frying pan, handle, and bag that doubles as pot insulation. If you don’t need the multi-fuel option, Primus already has the EtaPower EF (easy fuel) out for $80 less. Can’t wait till 2008? You can watch Primus’s online video about EtaPower stoves.

Primus EtaExpress

Built on the same heat exchanger foundation as the EtaPower, the EtaExpress is a compact, 14.7 oz, integrated canister version, designed for the solo traveler. It consists of a lightweight stove (2.9 oz) with piezo ignitor that mounts directly to an LP gas canister, a clip-on wind screen for fuel efficiency, and 1 L pot with fry pan lid. A heat exchanger mounted directly to the pot keeps the flame focused where it's needed, reducing heat loss, maximizing fuel efficiency and lowering boil times. The stove and a 230 g LP gas canister store in the 1 L pot for transport.
