MENSI New Updated QCC1 Type Propane Refill Adapter Hose for Filling 1lb Bottles from 20lb Tank 35.5" Long with ON/OFF Control Valve Easy Refill Tool

Nice product for refilling your propane bottles for Buddy heater

Refilling small propane bottles saves time, money, and cuts the ridiculous waste of throwing them out. It helps to have a forked screwdriver to open the pressure-relief valve while filling. This hose and its appropriate ends makes the rest easy. I also recommend the brass sealing caps available on Amazon for the refilled canisters, as those caps make them safer when they are full.

I ordered this to transfer propane from my grill tank to a 1lb tank. I was very sure to read the description to know I was picking the right thing as this is out of my element a good bit. It arrived and barely put fumes into the 1lb tank when my husband attempted the transfer. So he was sure I ordered the wrong item. I knew I had read it and it was not the wrong item! So I came back here to the page and put the time into reading directions. I'll never understand why men can't be bothered with directions... Sure enough Mr. I wont read directions if it would save my life was the 1 wrong here. This hose worked beautifully! LOL SMH

I was a bit apprehensive about purchasing this item, but after my first use -- its the real deal. Totally worth it.**First off: I am not a propane bottle filling professional. My comments below are not meant to guarantee a safe process on how to fill these bottles. Follow my lead at your own risk. (You have been warned.)**I filled my first batch of nine empty bottles -- all were Coleman Brand 16oz Propane bottles. I used a small digital scale to monitor fill progress by weight as I went. I was filling from a standard residential propane bottle that holds 15lbs of propane. It was fairly full (only used one time for my grill). I placed it inverted (upside down) in the sun, and had my scale & small bottle in the shade (I think this important -- will note later on.) After my first two bottles, I started cooling my bottles to fill in an ice bath before filling. (Remember High School Science kids -- a water-ice mixture is exactly 32degF.) It was a sunny day, but only about 65 deg F.The first two filled to 11oz: not great. By the last five, I had the routine down and I could consistently fill 14 ozs into the bottles by net scale weight in about five minutes plus or minus before the rate really slowed down. I think the weight could have gone higher, but personally, I am good with 87% full.So, conclusions?1. It probably will not fill the bottles 100% full (I don't know that I would feel comfortable filling that much).2. I started the ice bath to try to improve the transfer. Those first two that were only 11 oz? Yeah, they slowed down a lot sooner than the cold ones.3. Big tank in the sun? Again -- noticed on one bottle that the rate had slowed down and the sun had shifted so big tank was shaded. Push back in sun, rate improves.My conclusion -- you need the differential temperature to generate the pressure differential to move the propane. Having the small bottles cold and the big one warm really makes a difference.My calculation is that I break-even on this purchase with 12 refills ... it's great if you use many of these each year camping or whatever.

I own an adapter to screw the 1 lb propane bottles to the tank to refill them, but it was always inconvenient. I thought this looked like an easier way to refill the bottles and after the first use on 5 bottles I highly recommend it. While I did not follow the recommended procedure to place the tank in the sun and the bottles in the freezer I had excellent luck releasing the schrader valve to bleed the bottles as I had done in the past to get a good fill. NOTE it is important to not fill these bottles entirely full to allow for expansion. Therefore I tipped the bottle towards the schrader valve at about a 45 degree angle. this will ensure that when filling that liquid will be released while there is still an air gap on the opposite high side. As soon as it first spurts liquid, release the schrader valve and immediately close the supply valve. In most instances you can refill a bottle in about 1-2 minutes. I had one bottle where the valve would not fully open to allow escaping gas and that one took a little longer. There may be better tools, but I use locking forceps to grasp the valve. I had to grind off the edges to make it small enough to fit in the opening on some bottles. I've also heard that there is a split screwdriver type of tool that works well too.This seems to be a quality made product that is the most convenient method I've seen to refill 1 lb propane bottles.

Took only a few minutes to fill each 1# canister. Much more convenient compared to the small refill valves where you have to lift the large tank to turn the gas off and on between each refill.

It worked good for about 3 time usage. Then, the hose fittings leaked. I will not buy it again. Good thing I didn't purchased extra as back up.

This worked just great filling the small propane tanks with twenty pound tank. To fill have small tanks cold and use a small pair of needle nose pliers to vent the tank to push out air as you fill with propane.
