Review: Solid. Well made. Expensive. But you only live once and it’s BIFL. - My favorite propane tank I own. I have a lot of DOT legal, refillable, high quality propane tanks but I’ve never had one this tiny. The thing is absolutely cute as heck with a big grill lighting torch, or even a regular little pencil flame braising torch looks huge on top. It’s expensive but then again they aren’t selling a ton of these and they have high quality brass fittings and valves and it’s a high quality steel tank that’s gonna last for thousands of refills. What a little cutie this thing is i swear. Your buddies are gonna be like where the heck did you find this thing? “DON’T WORRY ABOUT IT CUZ.” 😂 Edit [allow me to explain the volume for folks who aren’t clear]: The capacity of this propane tank/bottle works exactly the same as for any other propane tank. The volume of the comtainer is not the actual usable volume. There are a few numbers to go over real quick and it will all be clear. For any tank, (1) there are 4 numbers. There is the total volume of the tank. That’s how the total volume of water it would take to fill the tank. (2) there is the amount of space you need to leave as vapor at the top of the liquid level (or “head”), which is 20%. (Propane expands and contracts A LOT compared to other fluids, approximately 17X as much as water expands and contracts.) (3) there is the amount of liquid that you never want to go below, or your minimum liquid level, which is also 20%. (4) you have the amount that is left over [from the initial 100% volume], after subtracting the 20% gas at the top to allow for expansion and also the 20% minimum liquid level that below which most normal appliances designed to operate at normal pressure will automatically shut off, which is 60% of total liquid volume. For a 20 pound tank, those numbers are: (1) Approximately 25 lbs or 5 gallons. (2) Approximately 5 lbs or 1 gallon. (3) Also approx 5 lbs or 1 gal. (4) 15 lb or 3 gallons Most people know that they only get a max of 20 lbs in a normal tank, which actually holds 5 gallons of water if filled with water. What many do NOT realize is that you only have 15 of these 20 lbs available as usable propane. The last 5 lbs is not available. Now, for the ¼ lb tank: The actual total volume of the tank is 3.85 oz. They say ¼ lb some places and they list the 3.85 oz number elsewhere. ¼ lb is rounded up. From there, you get a max fill level of 3.08 oz. (# 1 minus # 2.) Once you also subtract the last 20% you can not use, and the actual usable volume of the propane tank is 2.31 oz. So you will fill it the first time with 3.08 oz. If you empty it, it will be down to .77 oz. The next time you fill it, you will only fill it with 2.31 oz (plus or minus about .05 oz with each fill). Every other time you fill if after emptying will take 2.31 oz, plus or minus .05 oz. (That’s plus or minus about 1% to 1.25% total volume) So if reviewers say this is a ¼ lb bottle they are telling the truth—technically 3.85 oz is the correct number but they are def within spitting distance. If they say it only held 3 oz they are telling the truth. If they say they only get 2.3 oz of useable propane every cycle, they are telling the truth. It’s a funny thing. Hopefully this illuminates some of the haziness and confusion around this subject.
Review: Cool size - This is a good size bottle to use an adapter and pair with a backpacking stove. I used it for car camping to make cups of coffee. So far I have boiled 7 cups and still have about 10 grams left of propane. It is a little on the heavy side. About 300 grams for a full bottle. Add a BRS 3000 stove and the adapter and you’re looking at 358 grams. The BRS stove with a 100 gram isobutane canisters is 240 grams. Not a whole lot of extra weight, but you are getting more fuel with the 100 grams canisters. It would be nice to have a flatter “pancake” style 1/4lb as this can get top heavy. I’m 3D printing a base for stability. I love what Flame King is doing! The bottle holds about 50 grams, not a true 1/4lb FYI.

## Questions & Answers

**Q: Is there an adapter to fill these with a 1lb tank?**
A: Yes, you still use the adapter for 20 lb tanks and add a 20lb to 1lb adapter. This is readily available at your hardware store and it's purpose is to allow you to hook up a 1lb propane bottle to your BBQ for when the 20lb runs out in the middle of a cookout.  Sometimes called a "Steak Saver" HTH

**Q: Is tank suppose to leak gas after the bleeder valve is closed after filling?**
A: No it should not leak after filling. But the smell of propane is strong give it a minute after filling to air out.

**Q: Why is it called a 1/4lb tank? It weighs half a pound empty and only holds about 1.5oz of propane.**
A: It hold 50 grams of propane. I have filled two of these containers multiple times and 50 g is how much propane can be held. I have a YouTube viewer that independently verified the weight. 

The claimed 3.85 ounces is approximately 100 g which is double the actual capacity. Maybe the flame king company and explain. For fun I filled up one of these tanks with butane, and I weighed the fuel as 65 g.

**Q: Im loving how the cylinder looks, but is it a snap head or a screw on head?**
A: it is a screw on head, the same as standard 1lb propane bottles to screw onto propane torches and anything that takes those
