Perhaps Black Friday is a good day to start a thread about 2024 potential gift items.
I have used one pound bottles of propane for a long time but have always hated the thought of simply throwing them away when they were empty. Yes, I tried recycling them but found that difficult to do given the few places that will accept them. Yes, I tried connecting a hose to a larger tank but found that to be a bit cumbersome. Yes, I tried a five pound tank but didn't like it. Finally, a couple of years ago I saw a one pound tank (Flame King) that was (legally) designed to be refilled. But, there were a couple of design items of that tank that I didn't like. Finally, about a year ago the company that makes the Big Buddy/Mr. Heater propane heaters can out with a refillable one pound tank that seemed to be what I was looking for, so, I bought a couple - a Fuel Keg.
To use this tank I also needed what they call the Refill Kit. I've now used these tanks and refilled each of them three times with no problems. It is a simple process that takes less than five minutes (from dead start to putting everything back where I got it). A full one pound goes into each tank during the refill and they work exactly like the old disposable tanks but you simply don't throw them away.
Assuming that you can purchase the throw away tanks for $5.00 each and I refill each of the refillable tanks about ten times I will start to save money in addition to not adding to the landfill.
There are a ton of review videos (like THIS one) or (THIS one for Flame King) on YouTube.
Happy shopping!
