The Coleman Powermax Fuel Adapter allows any Coleman X-stove to run on conventional, more readily available butane-propane fuel canisters. That gives traveling adventurers the option of powering their stoves with either Coleman's proprietary Powermax fuel or standard, threaded butane-propane blended canisters. The innovative adapter also effectively converts the LP canisters into a liquid-withdrawal fuel system, to mimic the performance advantages that the Powermax system and X-stoves deliver: consistent performance throughout the life of the fuel cartridge, including strong performance at higher altitudes and in below-freezing temperatures. The lightweight aluminum adapter attaches to an X-stove fuel connector; two swing-out legs provide a stable platform for the fuel canister. The threaded butane canister is inverted and attached to the adapter upside-down to allow a liquid-withdrawal method of fuel-feed to the burner. This inverted liquid-withdrawal system results in more reliable performance in below-freezing temperatures, and is less affected by altitude than vapor-withdrawal systems.
