SMACO Mini Scuba Tank 1L Small Diving Tank for Underwater Breathing Portable Lung Air Tank Diving Oxygen Cylinder Kit for Emergency Rescue Boat Cleaning Backup Air Source Pony Bottle S400

I have to say this is one of the best investments I’ve made for underwater exploration. From the moment it arrived, I was impressed by the compact design, professional build quality, and thoughtful engineering. The S400 provides up to 20 minutes of dive time, which is perfect for short underwater adventures, emergency backup, or even quick maintenance dives. It’s lightweight, easy to carry, and surprisingly simple to use. I really appreciate the constant pressure exhaust system it makes breathing smooth and consistent, and the explosion-proof design adds a reassuring layer of safety. The double-layer filtration system is another standout feature. The air feels clean and fresh, which speaks to the quality of this product. I’ve used it for shallow dives around 30 feet, and it performs flawlessly. Also, the fact that it can be disassembled and taken on a plane makes it perfect for travel and spontaneous dive trips. Filling options are super versatile. I’ve refilled it using a standard scuba tank and the 8mm adapter it only took seconds! Knowing I can also use a compressor or hand pump if needed gives me peace of mind. The harness included is comfortable and secure, and the whole setup feels solid and well-made. I wouldn’t hesitate to recommend the SMACO S400 to anyone who wants a reliable, portable diving solution. Whether for fun, emergency, or utility this tank delivers.

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

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 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.

Waiting to long to get this one delivered to the house, but anyway it is very nice looking for scuba diving. Now i onlu need to enjoying with this.

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 !
