Move your fuel between canisters with a device that weighs less than a penny. The Alpenflow was dreamt up along the Pacific Crest Trail in 2023, after seeing piles of semi-filled rusting fuel canisters in hiker boxes. You can borrow fuel from hiker boxes, split canisters amongst friends, or consolidate your pile of half-filled canisters.
Specifications:
2.4 grams (0.09 oz)
Works with all threaded isobutane canisters (built per EN 417)
100% Made in USA
A refrigerator or direct sunlight also needed to drive transfer
Warm Your Donor Canister and/or Cool Your Recipient Canister
This transfer requires a pressure difference to push the upper liquid fuel down into the lower canister
The donor canister can be warmed in the sun, never use an oven or flame
The larger the difference, the faster the transfer will run
Place Warm Canister on TOP, Cool Canister on BOTTOM (no threading needed)
Press Down Hard for 5 - 10 seconds
Repeat as Needed, especially if filling a near-empty lower canister.
Once the warm donor fuel mixes & heats the lower liquid fuel sufficiently, the transfer will slow and eventually stop.
To mitigate the risk of liquid butane expanding when canister is heated, never fill beyond the original fill level (~80%)
Fuel canisters do not meet D.O.T. requirements for commercial transportation after refilling (a.k.a. it’s illegal for businesses to transport refilled canisters)
Never use a flame or oven to heat canisters
Never fill canisters with pure propane, and only transfer “winter mix” fuel (70% butane / 30% propane) into canisters rated for winter mix fuel.
Purple & pink plastics are a reinforced nylon blend molded in Fresno, California
Foam is molded in New Jersey but die-cut on Long Island, New York
Packaging is printed and cut in Irvine, California
Assembly is done in a lent-out cabaña in Atherton, California
Ping me if you have any questions! I might be snarky if you just aren’t following the instructions tho
