Hamans Gas Canister Refill Adapter, Fuel Transfer Device, Gas Bottle Refill Adapter, Portable Gas Pressure Valve Inflation Valve for Outdoor, Multifunction Camping Canister Bleed Valve

Good quality, not used as of yet, but looks like its a good product

I tried this for the first time just now. Did all the recommended prep - empty cannister in the freezer for an hour, donor tank warmed up in some hot water. Connected them together as per instructions and nothing! Made a bit of noise, but both cannisters largely the same weight afterwards, with the near-empty tank a little less than before.Tried this three times... no joy. Then thought I would just invert it, and connect the donor tank to the 'in' and the empty tank to the 'out'. Jackpot! I could hear the gas flowing, and after maybe 10 seconds I closed it off, purged the vent and disconnected both cans. The empty one (jetboil 100g tank) was up from 120g when nearly empty to 198g. For reference, I had also bought a new cannister of the same size, and that weighed 200g new.So it works, just probably a Friday afternoon version!

Good product works great Good value

I had 2 Coleman gas cannisters, one under ¼ full and the other about ⅓ full.I put the cannister with ⅓ gas into the freezer for 30 minutes as per the instructions and the other ¼ cannister on top of a WARM (not hot) radiator for the same amount of time.I fitted the adaptor on the ⅓ cannistor from the freezer first and then the warm ¼ cannistor. There was the faint sound of escaping gas but a final tightning stopped this quickly.When the twist bar (?) is turned to the + symbol the sound of the gas bubbling through can be heard (sounds like water running through a pipe). After about 30-45 seconds the noise stopped so i turn it off, pressed the small button to equalise the pressure between the cannistors and turned it on again. I did this twice in total.At a quessimate i would say the entire operation from screwing the cannistors together to unscrewing them when finished took no longer than 5 minutes but i would expect on subsequent uses that time will be less.Definitely worth the money.

Worked fine but poorly made from cheap materials. Threads on valve stripped after two uses. It is now in the bin and have ordered a proper one made using metal which is harder than chocolate. Buy cheap buy twice :/

Works great,Both supplied adapters are working fine.good quality

No problems, all works fine.As with any gas canister use, you do get the 'psssh' when attaching it but it doesn't leak and works as it should. Handy for organising and consolidating dregs in cannisters.Store mine in a little square tinder tin to carry in my cook kit.

Helps reduce waste, and saves time.
