I wanted a smaller propane tank for camping.Exactly what I wanted.I suspect most folks purchasing this 5lb tank are infrequent users of propane or are getting it for things like weekend camping. It's quite good for this.Some important notes if you're thinking about purchasing one of these for that usage, and don't have that much experience with refillable propane containers1. These containers must be purged before filling! They ship devoid of propane, and you need to expel the air inside and replace it with propane. This process requires specialized equipment usually...but later in this review I'll write a method for making your tank usable in a pinch.2. You must transport these upright, and ensure they don't roll around. Dangerous otherwise.3. Typical 5lb propane containers run between $40-70. Don't overpay. These are all basically the same. At time of writing there's a cheaper one from flame king.4. Mine arrived with manufacture date of Feb 2021 (arrived in May 2021) so only 3 months! Seems like others have reported up to 15 months old. Either way your tank is certified for 12 years so at (conservatively estimating) ~$10/yr in total cost, it doesn't really matter.Q: What if I already filled it blindly before purging?!If you already filled it blindly, you should try plugging it into a camp stove or whatever and see if you can get a consistent blue flame; chances are you can't. That won't boil water or cook food; you need to purge it.if you can't find someone who has the proper equipment (I live in the SF bay area and literally miles around -- there is basically nobody who will purge your container, only fill it) -- the good news is you can do it in a hacky way. What you need to do is get it filled with about half a gallon of propane. Or fill it all the way, that's okay too.The compressed air inside is lighter than propane, so if you leave it standing upright for some time it will mostly rise to the top. Now (without agitating it) take it to the middle of an empty parking lot away from anything that is flammable. Please don't smoke while doing this. Take a flathead screwdriver and turn the release screw. You should hear gas start to come out. Stand upwind of it and let it go for a few minutes. You can close the screw and feel the weight of the container to get a sense for how empty/full it is. You don't want to totally empty it, but get most of the propane you added out.Now go back and plug it into your stove and make sure it burns blue. If it does, you got out most of the air and you can go fill it up all the way. You probably wasted <$5 worth of propane. Also this is totally not the normal way to purge the container and it won't get the container as perfectly purged, but it works in a pinch!If you have more time, you can order a propane purge kit online. It usually takes quite a while to come though and will run over $30. Amazon doesn't sell them as of this writing.I needed a 5lb tank for my original Weber Performa Grill. My current tank had expired, which was a non-match replacement. This tank was the same design of the original tank. I purchased it online so it came purged and needed to be filled by an LP supplier. Turns out the tank would not take a fill. I contacted the manufacturer and learned that these small tanks have an issue with with the overfill check valve, in that if there is a surge of Liquid Propane, the valve will trip, then the tank needs to sit for 24 hours to clear the valve before another fill can be attempted. The trick is to connect the tank to the LP source, turn on the LP source and then slowly open the 5lb LP tank valve. This will enable the flow to start without tripping the safety valve.So the sellers need to include a notice about this method of filling. Also my newly purchased tank was over a year old, and the limit now for the life of a tank is 10 years from date of manufacture, so be ware most sellers are selling from stock that could be a few years old before you get it.Date of tank was acceptable manufactured July 2020 bought it March 2021.This tank filled weighs less than a 20 pound tank does empty.When I had it filled it took 1.1 gallons of propane, and I didn't do any special purge before hand. Ran my tent heater for 2 nights on low for about 10 hours a pop. Also ran my Coleman stove off it for about 30 minutes on medium heat, and there is still some propane left in it.In an attempt to escape the 1 pound green tanks I used a 20 pound grill tank last season. Quickly realized they are too heavy and too bulky for what I do. This thing is so much more practical its ridiculous.Use for small overlander camper.First time use. This past week. Great for week long trips and a bit more. Happy with seller and product. Find the price to be a bit more expensive then it should be. However you are not seeing 5lb tanks on the market as much anymore. Which I don't understand.Was made in Thailand. Other then that value is good, fill was easy, and most importantly it is small.The tank works fine, and saves a lot of money compared to the one pound tanks, but where is the quality control?A solid 2/3 to 3/4 of the knob was completely broken off (and not in the box), so it appears to have been that way when they put it in the box to ship out.I’m feeling like I’ve been had a little bit with this thing. I heard good things about the company but it is not a domestic made product and I feel I paid twice as much as I should have.
