Its compact, disassemblable design is airline-friendly, making it ideal for emergency rescue, boat cleaning, and backup air supply during shallow dives up to 16 ft, with support for deeper dives up to 100 ft. Multiple refill options and included harness make it a versatile, ready-to-go solution for professional and recreational divers alike. ## Description Product description Completely shut off the air source, no air leakage during storage. Underwater fluorescent display High quality, soft silicone, comfortable design and reduce jaw fatigue. Ensure the safety of the filling process Review: Excellent product - 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. Review: Surprisingly solid for its size - 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. ## Features - USING IT MORE SAFER: SMACO S400 pony bottle adopts constant pressure exhaust and explosion-proof device.The high-pressure gas in the bottle is decompressed and output through the decompression chamber,making breathing smoother and safer to use - RELIABLE AIR SUPPLY: The S400 1L scuba tank delivers approximately 75 breaths at 200 bar (tested at 16 ft depth).It incorporates a double-layer filtration system that effectively blocks dust and impurities, ensuring clean and reliable air with every breath - BOARD THE PLANE: After you disassemble the small scuba tank, you can take it on the plane and go diving anywhere.

The build quality feels solid, connections are tight, and it holds pressure well. Very compact and easy to carry, which is a big plus.

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. ## Frequently Bought Together - SMACO Scuba Tank Diving Gear for Diver 1L Mini Scuba Tank Small Diving Oxygen Cylinder up to 20 Minutes Dive Time Portable Diving Tank Kit for Underwater Exploration Emergency Rescue Pony Bottle S400 - Creation Core High Pressure PCP Hand Pump Air Filter Water-Oil Sparator with Female and Male Quick Connect for High Pressure Air Compressor Pump 30Mpa Blue - SMACO PCP Air Compressor 4500Psi/30Mpa High Pressure Air Compressor Paintball Scuba Tank Compressor HPA Pump Fill Station Auto-Stop,Oil-Free Powered by 12V DC or 110V AC with Water/Oil Separator --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/268488613-mini-scuba-tank-1l-small-diving-tank-for-underwater-breathing](https://www.desertcart.hr/products/268488613-mini-scuba-tank-1l-small-diving-tank-for-underwater-breathing) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-16*
