This was a very good tool for filling up my mini propane bottles that I use on my camping trips. It saves me a lot of money from having to buy new ones and then just throwing them away so it’s nice to be able to recycle them.

High quality and works great. Here's the science, without math. When a tank is half full, half the contents are liquid (LP=liquid propane) and half are gas. The liquid turns to gas until a certain gas pressure is reached inside, equalibrium. Opening the valve lets gas out, reducing pressure in the tank causing more fuel to turn from liquid to gas as fast as you use it. When you burn all the fuel, the gas pressure inside becomes that of air, well below that of a tank still having liquid inside. An empty little tank will partially fill from an upside down big tank, because the little tank's gas pressure is lower than the big tank's pressure. But, as soon as some liquid gets into the small tank, it starts to turn to gas because the little tank's pressure is low. For all gases, PV=nRT where nR is a constant and thus Pressure times Volume is proportional to Temperature. When you put your little tank in the freezer, you lower the temperature without changing the volume (i.e tank size) so the pressure must go down. If the small tank was empty to start with, the pressure was already low, that of air, and now it becomes less than air. If the little tank wasn't quite empty, its pressure starts high and goes down some, but not as much as if it were empty. Connecting the big tank to the little tank, you want the little tank to have as little pressure as possible. It is thus best if it emptied and then chilled. The big tank's liquid is at the bottom when it is inverted. The big tank pressure is higher than the empty and/or cold small tank, so liquid goes from the big to small until both tanks are at the same gas pressure. The little tank's pressure goes up as liquid transferred to it turns to gas while the volume for that gas is being reduced by the entering liquid's volume. Because it is chilled, that pressure is not as high as in the big tank. At some point, the little tank's pressure reaches the big tank pressure and liquid stops transferring. With regards to overfilling a small tank, the physics seem to indicate that is not possible, but there's a catch, so keep reading. Here's what might be happening. The small tank is chilled and then mostly filled with liquid, leaving just a bit of space for the non-liquid gas. The two tanks are equal pressure so the small one is fully pressurized. It gets disconnected and then starts to warm up. Remember, PV=nRT. With the volume constant, when the temperature goes up, the pressure must go up. Since it was at full pressure when it was cold, it is now over pressurized and thus could cause tank bulging. Without doing the math, it's not clear how much overpressurization will occur. There are a lot of variables here, like how hot was the liquid from the big tank and how long filling took and how much warming of the small tank occurred during filling. Some reviewers suggest poking the valve with an Allen wrench to let the gas out to fill with more liquid. It will reduce pressure temporarily or overpressurization as it warms. After you poke it you need to quickly reattach it. Now, back to the catch about overfilling. If your stove runs with the tank not fully upright but the tank is 99% full, what will come out? Liquid. Will it turn to gas before it gets to the burner and what will happen if it doesn't? I don't know and don't want to find out firsthand. Best to use the scale and let some out if you've overdone it.

It takes some experience to do it safely and in proper sequence (bleeding the gas, cooling the refill container, not contaminating the refill with air, etc.), but after three or four ~1lb. refills I was glad I bought it. I'm doing 3 more next week. It was already paid for after the the first three. Do wear leather work gloves and safety glasses though, don't tempt fate. Oh good hint...when you flip the gas cylinder, keep the refill shaded/wrapped in some insulation (a blanket, etc.) and face the cylinder to the sun...goes much faster.

Had the Black one years ago and it Worked fine a few times, no issues, then sold it. Years later then tried the Mr Hearer brand variety, and it always leaked one gust of propane out every time attaching it and required pliers, and the valve on my standard tank went bad and could no longer be refilled at the refilling stations, and I blame the Mr Heater brand one for breaking it. So I ordered a 2 pack of the red ones this time, 1 looked a little scuffed up in the threads as if it was used, and the other 1 looked fine so I used it, and on the first fill it worked perfectly, nice and full fill, no pliers, no leaks, no issues. Excellent device, I only needed 1 anyway and the 2 pack was the price of 1 anyway. I like how it does not insert inside the standard tank like the Mr Heater ones do. In the past I remember the black one did not fill my green bottles very well, and the Mr heater one did better in that regard, but this new two pack of red ones I got, they filled the green bottle I filled just as full as the Mr heater brand one was able to get them. Without doing any funny business techniques you hear/read about, they get about 2/3 full. I have tried putting the green bottles in the freezer 30 minutes prior to refilling them and it helps a little more go in, but not enough to go to the trouble. I would estimate you only get maybe an extra 1/6 fill by putting them in the freezer. I mean, if you're already leaving your standard tank out in the sun heating up anyway it's the same deal, as long as your green bottles are in the shade.

This product is designed to be used to connect a 20- or 30-pound propane cylinder to a 1-pound propane cylinder so that liquid propane may be re-filled into the 1-pound propane cylinder. The 20- or 30-pound cylinder must be placed in an upside-down position and the large cylinder’s valve used to allow the liquid propane to flow into the 1-pound cylinder. Please note that extreme care must be used when refilling such 1-pound propane cylinders to ensure that re-filled cylinders are not over-filled. Re-filling the 1-pound cylinders must be accompanied with a weight check to ensure that they are not over-filled. This product consists of a QCC1 Acme Nut connection (Red) that is rated for a 400,000BTU/hr flow rate that is connected to a male CGA 600 connector. The CGA 600 connector is a 1” X 20 threaded connection that is found on the one-pound propane cylinders. The connection is sometimes called a “Throwaway Connection” since it is seen on the one-pound disposable propane cylinders. This is the most basic connection that can be made between a 20- or 30-pound propane cylinder and a 1-pound propane cylinder. This product appears to be made of high-quality brass components and should last a long time. I am happy with this product.
