FANOVO Propane Filler Adapter 1 Pound 304 Stainless Steel Braided 1lb Propane Tank Refill Adapter with Gauge & Shut Off Valve QCC1 Inlet Propane Bottle Fill Converter Connector for 1lb Samall Bottle

Love the hose and gauge. Gauge indicates how much fuel in large tank.Good value for money.

Exactly what I was hoping for.

Overall good product. I got the stainless steel braided one and it’s stiff.Still functions as designed.

First, this works great now, but it took a lot of tinkering to get it to work. Directions are not helpful at all. Since your reading this, I'll let you know how. I put the little tank in the freezer for several hours, then screw it in and put the big bottle upside-down higher than the little one. If you get it cold enough, it will take 1-2 minutes and Bob's your uncle.

Filling up my little tanks for heaters and saving bunch of money . It's safe and affordable .

Worked great for a month than started leaking from ball valve stem.Edit: company reached out and made things right

Propane, much like butane, sinks in the atmosphere, they call that a creeping gas because it stays low and spreads out. Inadvertently some atmosphere gets into the tanks when changing the connection. There is a valve on the bigger tanks that vents & it is opened when filling it. Liquid propane is pumped in & any air is vented. They stop filling when a bit of the liquid starts to exit the vent, then they close the vent and stop the pump. So the small tanks have basically a Schrader valve, like a tire has, on the top beside the threads. If one were to open that during the refill of the smaller 1lb tank, I think it would fill faster, require less of a temp difference, & make it more filled. I am buying one today and trying it, I have two to fill so I am doing the method in the ad first to give it the advantage of a tank with more in it. I will also weigh both and note their torch time. Same nozzle style torch, identical tanks, burns with only one setting. I feel like having atmosphere in with the LP, air would always be forcing the propane out, filling slower from resistance & ejecting LP while in use, shortening it’s work-time. Why does the professional, required to be certified mind you, open a valve? Why does the 1# bottle have a needle valve? It would have to be done carefully regardless of methodology. The process will take a few days, but I use torches a lot & will report my data forthwith.

It's works as it should unlike the others
