0.5L Mini Scuba Tank with Pump | 5-10 Mins Portable Divng Lung Tank for Snorkeling, Freediving & Emergency Backup | DOT-Certified Air Cylinder

Bought this kit for doing a pool repair. Filled the tank and got under the water and did the repair. Had to refill it several times but without this air tank, I could not have accomplished the task. I would say it is good for about 5-10 mins per a fill depending on your exertion level during use.

First of all the pump barely blew any air. It literally blew less air then flatulence. It took me almost an hour and a half to pump it up, roughly 700 pumps. I barely got the needle into the yellow before I heard a loud pop! Pump hose popes (see photo) then it started leaking air and I was afraid it all my hard work with leak out but Then the nozzle that hooks to the tank wouldn’t come off. I struggled with it for 45 minutes. So I’m going to have to ship this thing back with the nozzle still attached because I can’t get it off.

waste of time filling will be returning. Counted 500 pumps and it is at 1000psi

The media could not be loaded. Love the idea of this! Came boxed perfectly and easy to assemble. This could also be used outside of scuba diving ! I used it while in the pool as well for a longer swim !

I got this product to extend some snorkeling time and depth without going full scuba. Basically instead of just diving 10 to 15 feet down and holding my breath, I wanted something where I could take a breath or two while I was down there before coming back up to the surface a minute or two later. This seem to fit the bill perfectly.After getting the product, the box appeared exactly as as shown in the product photos so you definitely get what you order. And I was able to quickly follow the visual directions assemble the product. Once the pump was connected to the bottle after initially pumping the pump per directions for a while to make sure that it was completely clean air going in, I was able to pump up the cylinder to about 15 Barr. Now according to the instructions, it should be able to hold more pressure than that but honestly, I just got tired of pumping. Perhaps when I actually go with this to the hotel rather than testing it at home I will pump it up to its full capacity, but for now just to test and make sure it work this seem perfectly fine.After unplugging the air hose, I was able to use the mouthpiece and breathe from the bottle. It didn’t feel the same as a real scuba rig that I used before, but sufficient air was coming in that I felt for my extended snorkeling would be perfectly fine the dial Showed the current pressure in the bottle and that could be used to make sure that you have sufficient air and that you don’t go down not knowing how much air is in the bottle. I didn’t notice a slight smell or maybe even flavor to the air in the bottle as being an I didn’t notice a slight smell or maybe even flavor to the air in the bottle as being a bit oily but I expect that will get better with time and use and I will probably thoroughly clean the inside of the air bottle before I actually go on my trip to minimize any kind of smell or taste. I give it 4 1/2 stars but there is no half here so I’m just going to leave it at four stars and say that you will get exactly what you ordered just bear in mind that the amount of pumping that you will need to do is probably more than you expect

Easy to use…. Works great…. Takes a long time and hard to fill with the pump…. Only con I have found so far is that…. If it was easier to fill with the pump would have gotten 5 stars…. But I understand the hand pump is gonna be harder….

Do not buy. Tank leaks

I can finally scuba anywhere, anytime! This is very easy to assemble, comes with great instruction booklet.Extra o-rings and other small replacement parts included as well!
