DOZYANT Propane Refill Adapter, LP Gas Cylinder Tank Coupler - Fits QCC1 / Type1 Propane Tank and 1 lb Throwaway Disposable Cylinder Propane Bottle Connector

Saves me TONS of money!! Works great and easy to use. Screw onto large tank before attaching 1lb tank. Turn upside down and it fills the small tank right up. I fill my big tanks at Costco so this is going to save me lots of money.

Does what it is supposed to, easily and well.

work good

Works perfectly it's a money saver

The product is well made and no leaks when properly installed. HOWEVER, for this product to effectively transfer propane from a larger tank into the small one pound tank there needs to be a temperature differential between the two tanks with the smaller receiving tank considerably colder than the supply tank. I tried for the first time with the larger tank having been stored outside (45 degrees) and the smaller receiving one pound tank having been stored in my garage (55 degrees). What happened was the one pound tank (it had about 20% of fuel still in the tank) emptied into the larger tank. Videos say to chill the small receiving tank first but I wanted to try just to see what happens. The warmer of the two tanks will transfer propane into the colder of the two tanks. It's a good product that will work if one makes sure there is a temperature differential .... supply warm, receiving tank cold.

I was unfamiliar with using propane and especially refilling the 1 lb bottles from a larger tank. This seemed like a decent price and the reviews were favorable.For anyone looking to do the same thing I do which is use a small propane heater which runs off of 1 lb tanks this is definitely a better value than buying pre-filled tanks. Attaching the large black knob end directly to the 20 lb tank is easy. It has a nice grip to it so it could be attached firmly. The 1lb tanks screw easily into the smaller brass side. I always make sure to snug it down and when removing it I just hold the brass fitting to loosen the tank slightly then the tank unscrews so that I keep my hands well away from any vented propane.I did purchase brass caps to put on the refill tanks in between uses. If you use those caps with a gasket inside of them be careful the gasket doesn't stick to the 1lb tank. If you attach a tank and that extra gasket gets in there, the valve won't completely open so it's more difficult to fill the 1 lb tank to capacity. Otherwise it's been a flawless process and I have saved a lot of money on propane. I just emptied the last of my first 20lb tank with no issues. The last bit doesn't want to come out quite as readily. Be sure to use the freezer technique on the 1lb tanks & have your large tank as warm as possible by sitting it in the sun etc & you should have no concerns. The greater the pressure deferential between the two the faster the transfer will be & your tanks will fill closer to their capacity.

Used product as directed worked very well and would recomend product only issue was it was late being deliverd now got conversion adapter for my iso butane stove to propane. Is very nice to have options for fuel

I bought this after talking to a friend but as he had never used one he couldn't say that it worked, well I can. I followed the simple directions , put the empty bottles in the freezer for a few hours than connected the 1 lb bottle to the adapter then screwed it onto the tank inverted the tank and in less than a minute I had a full 1 lb bottle. I weighed the bottles before and after and they actually filled to just over 1 lb. Now I don't have to spend $3+ for one lb of propane when it only cost about $0.83 lb . We use the 1 lb for our Mr Heater Buddy in our TT to take the chill off. One note I think it works better to attach the adapter to the large tank first then the bottle. Also note that the bottles are very cold after spending a couple of hours in the freezer so maybe some gloves. When unscrewing the bottle do it quickly as some of the gas will escape as you remove the bottle. I think this is a great addition to our camping gear and highly recommend it to any one who uses 1 lb bottles and now I don't have to throw them away any more
