16 oz propane refill

Wear gloves.

The amount of spray you're risking isn't enough to be all suited up, but it will be more comfortable and a bit better than if the -40F liquid does pfft a bit on your skin.

MAKE SURE THE VALVES ARE OFF BEFORE DISCONNECTING!!!

NEVER TURN ON THE MAIN GAS WHEN THE SMALL BOTTLE'S VALVE IS OPEN AND NOT CONNECTED!!!

WEAR EYE PROTECTION!!! Your eye likely will NOT be happy if -40F hits it.

Not a fire risk, but a physical, send you to the hospital risk of a violently whipping around valve risk.

Filling a different kind of bottle a bunch of years back, I had a "helper" who mixed up the order of things and told me the big tank was empty.

As he turned on the big tank, I tried the grab the valve but too late. I took a valve to the face. Fortunately the glasses protected my eyes, but I had two mighty cuts on the cheek and eyebrow that required repair.

Be smart and be careful.

Also know that propane is heavier than air and will collect at your feet like puddles in dips and stuff. We're talking about big leaks, not pffts here and there.

End of safety message :)

I have refilled 1#'s, but now I have 2 small 5 (?) pound regular tanks. They are a smaller version of the standard 20# tanks. Same price per gallon at Tractor Supply as filling a 20# tank.

SAFETY and INTELLIGENCE can confuse some folks.

"Checked OK when filled - but leaked later" may be a sign the bottle was overfilled.

Filling by exact weight is VITAL. Eyeball to bottle I have seen overfilled bottles BULGE. Note the plural conjugation of bottle. The relief valves did not pop. Bulge so bad they wobbled.

Even a digital bathroom scale can be used if empty bottle "tare weight" is Factored. Wear gloves. Vented liquid WILL cause frostbite.

A forced heavy liquid vent (bottle upside down) cleared many leaking ports for me.

This was done down here where dozens of campers showed up on a remote beach. 1 lb bottles were not available anywhere. One guy showed up with 30+ bottles from another camping beach 35 miles away. The were desperate for lantern light.

I not only froze the bottles I left the 20 lb pot out in the sun. Put a 1/32" restriction orifice with valve inline with fill hose. Charged a buck a fill and my man Rodrigo made a fortune at eqvt 50 cents a bottle while I snoozed in a hammock. Too many bottles refused to seal. Two blowdowns and it failed the test. I smeared lanolin onto the bottle threads.

Or they understand exactly how it works...

they are so easy to fill there is no need to get them full.

Trying to use up the partials folks give me means I rarely need to refill.

The number of leak failures complained about really takes the bloom off the rose with the Flame-King. Maybe I'll just spend the forty dollars and get a canteen shaped Mexican 10 liter pot which could not be refilled in the USA.

I have 4 of the flame kings, and in the year I've had them, I've had no issues with leaks. One key is to open and close the fill vent correctly with the correct allen wrench. and don't overfill.

but that is a sampling of only 4 bottles.

And I have yet to have a non refillable leak on a refill either. I just weigh them when done to make sure they are not overfilled and do a quick soap test on the schrader valve.

the 1 gallon or 2 gallon tanks make lots of sense for anything that doesn't need a 1 lb cylinder. but then kinda hard to tote around a coleman lantern with a 2 gallon tank in tow. or my tabletop patio heater.

U-Haul has refillable 1# propane bottles. I'd just go with that... they may be a bit more, but you can reuse them safely.
