The ultimate stove: anywhere, anytime, any gas

Finally. For years, we’ve been hunting for a multifuel stove that burns both liquid gas and canister fuel, burns them equally well, and easily converts from one mode to another. The Universal is that stove—and possibly the last one you’ll need to buy. We cooked it side-by-side with a half-dozen current and past multifuel stoves, and testers from BACKPACKER and CLIMBING reached this verdict: It burns as hot and efficiently in liquid-fuel mode as any; it performs better in subfreezing and high-altitude conditions; and its field-fixable and -cleanable construction gives it an advantage in a category notable for the importance of durability (a failed stove would have ended our trip in Chile, as we had to melt snow for drinking water).
Even better, it solves the two challenges historically plaguing multifuel stoves: lackluster performance in canister mode, and clunky conversion processes with too many steps or pieces. In controlled conditions, it beat every other multifuel stove in boil-time tests with canisters, and compared favorably with (and even beat some) dedicated canister stoves, especially in cold temps. That’s unprecedented, and it’s due to engineering that inverts the canister and burns the fuel evenly. The technology, called AirControl, adjusts the oxygen/fuel mix to prevent the steep tail-off commonly seen as fuel pressure drops. And switching modes only requires two steps: swapping jets on the head of the fuel line, and attaching the new nozzle to the fuel pump (liquid gas) or canister.
Testers had two gripes—priming can be futzy, and you must take care not to lose several small parts—but overall they agreed with an editor who called it “the new benchmark for stove versatility.” $140; 11.5 oz. (liquid-fuel mode); 9.5 oz. (canister-fuel mode); cascadedesigns.comState of the art cookware and revolutionary stove design combine to create the fastest, most fuel efficient stove system ever. The Reactor’s radiant burner is enclosed by a unique heat exchanger for unmatched performance in windy conditions while an advanced pressure regulator provides optimal heat output over the life of each fuel canister. Stove and fuel canister stow inside of the high-efficiency 1.7 liter pot that’s great for everything from solo trips to cooking for groups of up to three people. A collapsible handle locks the unique see-thru lid in place for safe and easy transport.
