S400 Mini Scuba Tank, 1L Portable Diving Lung Air Tank | Aluminum Pony Bottle, DOT Certified, Reusable, for Recreational Diving, Pool Training, Boat Cleaning, Beach Vacation & Travel

Excellent experience. The application works very smoothly and is easy to use, even for people who do not have much experience. I really liked the organization of the tools and how intuitive the whole process is. In addition, it allows projects to be created quickly and efficiently. I certainly recommend it for those looking for a practical and functional option.

I bought this mainly as a backup / short underwater use option, not a replacement for full scuba gear — and for that purpose, it works exactly as expected. The build quality feels solid, connections are tight, and it holds pressure well. Very compact and easy to carry, which is a big plus. Air time is obviously limited (as stated), but if you manage your breathing and know what you’re buying, it’s totally fine. Setup was straightforward and everything arrived as described. I tested it carefully and had no leaks or issues. This is not for deep or long dives, but for short underwater tasks, surface dives, or emergency backup, it does the job well. Good value for the price if you use it correctly.

This tank is amazing for a beginner snorkeling tank. So far with practice I can get 17.5 minutes of air. It’s so easy to set up and fills at home in 20 minutes. We bought a portable compressor so we can fill it at the beach from our car. Best purchase so far this year! Great quality tank and rebreather. There is no better quality for the price.

Muy bueno el producto en buen estado, me gusto, pero estuve muy preocupado porque no me informaron a que servicio de entrega fue el que recibió en mi País Ecuador, en Amazon salía como entregado pero aun no recibía nada, estuve asustado, pero averiguando veo que lo tenia Servientrega, lo retire 3 días después de la entrega programada.

Love this tank! Very portable, and use it in pools to do maintenance and for fun. Looking to take it on vacation soon. I have two different size tanks. The half liter I can stretch to about 12 minutes of air time and with this one liter, I can get it to between 15-20 minutes. I had one issue with the respirator where a piece got stuck closed and I couldn’t breathe, but it’s easy to unscrew and fix. Maintenance is a breeze with additional gaskets/o-rings provided, but haven’t needed them yet. Stay away from the hand pump. It just takes too long, but you’ll get a good workout from it. The half liter took a couple hours to fill with a hand pump. Get a small air compressor to pair with this. This is not for the serious diver unless you’re carrying it for backup air! I am not yet certified in diving but can say this is good for a multitude of tasks. Pool/boat maintenance, shallow diving for spear fishing, exploring shallow ponds and lakes.

I wish i had purchased this earlier. What a great compact way to travel with diving gear!

I always wanted one of these to work in pool or under boat. When saw this had to jump on it. I was blown away by the quality of the feel and the machining. Is airlines safe and easy to hang off a knapsack. Great value and can’t wait to use it next month.

So I'm very familiar with pressurized gas and obtaining it due to my job (unique kind of welding). Due to liability reasons even though the air used in scuba is the same that comes out of a compressor one might use for a nail gun or sandblaster you need a scuba certification to get it filled. I was always under the assumption that scuba tanks contained some mixture that had supplemental nitrogen and other gasses added to make it safe but it just is compressed air. Looking back I might have just been told that when I asked why pure oxygen wasn't a viable option. This tank comes with a "certification" that says it has been tested but this is no more than a card the manufacturer made themselves and means nothing to a professional shop. So usually when you get any gas filled they need a hydrostatic test and inspection that's valid to make sure the tank is safe and clean enough to be filled with something you will inhale or something that if not properly contained would make as decently sized crater even if this accident happened on asphalt. This is usually a 25$ test at most and happens in a day, most shops with nice owners won't even make you do it as long as they trust the shop that the tank has been filled at before and most tanks that you fill have been around for 60-80 years. Sorry for this off topic fact but oddly enough most people who fill these for work have ran into 3-10 tanks stamped with the symbol commonly used by that the evil guy with the funny mustache. If you ever see a tank with 4 boxes it's because that's the easiest way to cover that up. So even though it's common practice to get a tank that was made before youre grandpa was born, those in the know would trust a tank from back then more than one made this year in China. Even though you can just hook a compressor up to these unless youve been instructed how to use one to breathe in a safe manner going even 10 feet under could be fatal. It's easy to assume that you just need to let the air out and breathe it in but without doing lung exercises and using proper technique there's a sliver of a chance the expansion that happens to your lungs could be fatal. So even if youre built different and can handle stuff like that I found that it was harder to get this filled than it was for me to get a tank of hydrogen when I was 17. I still might try it anyway because I'm also built different 😂 but I'm going to make sure I have a partner with me and talk to an experienced diver beforehand. Hope everyone who reads this gets to live out their fantasy of being a mermaid safely. This is not the best route.

I work in the film industry in the Stunts department and purchased this product for a specific Stunt where I had to use the equipment in a confined space and it worked exactly as advertised. I am very happy with the product.

A really cool piece of kit, pumping it up is a nightmare though. I'd suggest buying an electric pump (with filter). Easy to set-up and use. Getting about 25min out of a full tank.

For my use these pony tanks work. Underwater photography. I still have not filled them to the psi that is suppose to be the max. I hve trust issues when it involves a explosion in my face. I fill using diving tanks and a jumper hose/regulator. Not the hand pump. If a hand pump is your goto you will be disappointed. The air Gauge is crap. I would recommend the manufacturer start using higher quality gauges as sometimes they stick or you run out of air and the gauge has just hit the red mark, no reserve. NOT FOR CHILDREN AND NOT FOR THE INEXPERIANCED unless your only going a few meters down

Product is not suitable for Canada …professional scuba divers shops refuse to fill up the tanks..

Je suis un plongeur certifié et j'ai acheté le produit pour des plongées en eau peu profonde et le produit m'a vraiment impressionné. J'ai réussi à obtenir une autonomie de 25 minutes à moins de 20 pieds de profondeur avec un remplissage à 300 bars (45 minutes pour remplir avec un compresseur de 4500 PSI) ! Je vais donc acheter une 2e kit afin de plonger avec 2 bouteilles. Il peut également servir de bouteille de sécurité. La courroie transversale par contre qui maintient la bouteille en place est moins intéressante et lorsque la bouteille est en place, le cadran de pression est plus difficile à lire. D'un point de vu prix/qualité, je recommande le produit !
