Propane Refill Adapter with Valve and Gauge, Fill 1 Pound Bottles from 20lb Tank, Fits QCC1 / Type1 Propane Tank and 1 lb Throwaway Disposable Cylinder Propane Bottle Connector

Works like a champ. However, when I first got it, I simply tried to fill a small 1lb cannister from my 20lb tank. Did not work. Until I watched some videos on how to do it. I know you have to turn your big tank upside down. Propane is a liquid. Then hook up the small cannister. But that did not fill it. You have to release the pressure first from the small cannister. So I took a small Phillips head, pushed into the small cannister and released air for a good 10 seconds. Then and only then was I able to fill it. You can hear the gas go in. When it stopped, I released more pressure and was able to fill in more propane until it was full.

Awesome to fill refillable and works great.

I've used the CALPOSE Propane Refill Adapter to add about 8oz to the 1lb canister. I think I can add more Lp into the 1lb canister, but it will require additional steps. 8oz is easy enough.

Worked Fantastic ti refil the little green tanks! Worth Every Penny!

I was pleasantly surprised at how well this worked. I was able to refill two small canisters without any problem. It is simple to set up and use, and I had no issue with gas leakage. I assume it works best if your filler tank is full.

Cheap and easy to refill tanks

Works on my refillable Flame King 1 lb. cylinders.I prefer ball valve adapters,just my opinion other designs also work well.

The propane refill adapter is easy to use, makes life more convenient and saves us money. The gauge allows you to visually see how full the tank is. We refill our small green propane tanks from a large tank with the refill adapter. You do have to temporarily open the air vent on the green tank in order to get the green tank completely full. Make sure you close the air vent when your small tank is full.
