Review: I'm giving it 5 stars because all the issues I found with it are well known so couldn't really be considered defects. As best I can tell after a half-dozen uses it is as advertised and good quality. I bought this product partly for fun and partly so I could dive in my pool to do things like inspect the plaster, scrub at algae, clean the drain cover, remove and replace the light with ease. I'm only diving to 8 feet depth so risks of diving like blowing up your lungs because you didn't exhale going up are not an issue I have to worry about. I do not intend to use it in the ocean. If I had a boat I might use it to scrub the keel at a max of 10 feet depth but I'd have to get a compressor and probably a 1 to 2L tank instead. Like many others have reported: a) pumping it up is a real chore. I go with 100 strokes at a time and take a couple of minutes break. Once over 100 bar it is getting real tough. Take it slow! Make sure you release the pressure in the inflation tube with the bleed valve before releasing it from the tank or you will get one hell of a bang and tube flying out of your hands. Fortunately I only made that mistake once when the pressure was still low, I would not like to have done that at 200 bar! I do find it a little scary pumping up the cylinder. I reckon at least with a separate electric pump I could have it inflate in a different room where it won't blow my leg off it exploded for some reason! b) 0.5L at 200 bar is about 100 liters of 1 atmosphere air and maybe 100-200 breaths at the surface. You'll get fewer breaths as you get deeper because at 10 meters (33 feet) the pressure is 2 bar so your breaths will consume twice as much air (make sure you exhale as you ascend!!!). With an average rate of respiration at surface depth you could eek out 10 minutes but my experience as a novice diver not trained in breath holding or skin diving is closer to 5 minutes. It could be even less if you're not comfortable with the whole breathing underwater situation and especially if you don't have dive weights and are working hard just to stay down. As the pressure goes down you'll have to work harder to take a breath which can be a bit alarming so you're never comfortably going to use all the air in the tank. That said IMO this is a nice sized device for infrequent short shallow dives. I could not imagine taking it to a beach - I wouldn't want to risk getting sand or salty water into the pump. Even if I did I would want the full-face combo mask they sell so I could snorkel and then only use tank air when diving. I'm not sure how well that works but it would be essential to maximize the fun. I'd really like to use this to practice breath holding - but the effort of pumping it up makes that a real chore. After getting it to 200 bar I need a lot of time to relax and get my heart rate down so it is a low ratio of dive to pumping time. Really I need to spring for an electric pump but so far I'm not convinced I want to spend the $200 or so extra for that. For shallow task diving you could also argue that the surface floating low pressure dive systems with a tube you breath out of (like a long snorkel) are better suited and give extremely long run times albeit with decreased mobility due to the tube (they are also mostly $1000 or more so at least double the cost of a tank based system like this with a compressor). Review: Tried this mini scuba tank and it’s awesome for quick dives or snorkeling. Super compact, easy to carry, and fills up fast. Perfect for beginners or anyone who wants to explore a bit underwater without full scuba gear. Feels sturdy and well-made, great for travel or boat trips. Definitely recommend if you love the ocean! ## Features - 【HOUVAN H300】HOUVAN H300 scuba diving tank has a capacity of 0.5L up to support 10 minutes of underwater breathing time, and the specific use time is determined according to the breathing rate, diving depth and other factors. The Houvan H300Plus mini dive tank is small in size and weighs only 2.38 pounds. The H300 is equipped with an anti-loss rope and carrying pouch, so you can go hands-free underwater and don't need to carry a traditional heavy diving tank. - 【High Quality】The whole bottle body of HOUVAN H300 mini scuba tank is made of 6061 aviation aluminum, and the three-layer process of washing casting, frosting and sandblasting is adopted, which makes it have better corrosion resistance, can better resist seawater corrosion, and protect the scuba tank body from damage. There is food-grade silicone in the mouthpiece part, which can be used with confidence. - 【Professional Design】The valve head adopts a constant pressure outlet device, and the high-pressure gas is depressurized and output through the decompression chamber in the bottle. With 5K explosion-proof valve, when the pressure inside the bottle reaches or exceeds a fixed value of 5000psi, the gas will break through the internal explosion-proof copper sheet and leak out to reduce the pressure in the bottle.Once the explosion-proof copper sheet is damaged, it needs to be replaced before diving. - 【Inflatable Method】If you have a diving qualification certificate, you can inflate directly at the dive shop; It takes about 4-8s to inflate with the HOUVAN scuba adapter; You can also use the HOUVAN air compressor to fully charge in about 11 minutes; Inflate with a HOUVAN mini high-pressure manual pump, which takes about 25-30 minutes. It is more difficult and is recommended as a backup device. Working pressure: 3000PSI/200bar/20Mpa. - 【Services】You can get：HOUVAN H300 scuba tank，anti-lose rope, user manual and some other additional accessories.
