VEVOR Scuba Tank, 1L Portable Diving Tank, Diving Oxygen Cylinder Support 15-20 Minutes Underwater Breathing, 98.43 ft Diving Depth, Refillable Snorkel Air Tank with Pump for Underwater Exploration

15–20 Minutes of Air Supply for Extended Underwater Exploration

The VEVOR 1 litre scuba tank provides enough compressed air for about 15 to 20 minutes of continuous underwater breathing. This gives casual divers and divers some substantial time to explore without hurrying back up. This window covers most recreational dives at shallow to moderate depths. This feature makes it useful for reef viewing, underwater photography, and quick hull inspections. For beginners on their first dive, this period offers a comfortable introduction without the bulk and complexity of full-size scuba gear.

The tank also provides a reliable backup air supply for trained divers who wish to have emergency reserves for longer dives. It is rated for a maximum depth of 98.43 ft or 30 m, the range in which most of the world’s recreational diving activity takes place. Whether you are exploring a quiet cove on vacation or storing a safety cylinder aboard a dive boat, the 15-20-minute supply window makes this tiny gadget a valuable piece of diving gear.

1 Litre Scuba Tank with 20 MPa Pressure Rating for 30 m Depth

This is a very small overall size, measuring only 3.50 x 14.17 inches, with a maximum pressure rating of 20 MPa (2900 psi) and enough breathing air. That pressure capacity means a single liter of internal volume can support minutes of underwater use, rather than a handful of breaths. The rating also sets the safe operational ceiling at 30 m, which covers the vast majority of recreational and light professional diving situations.

All parts exposed to such pressure, from the valve assembly to the cylinder walls, are designed to withstand multiple cycles of filling and emptying. This 1 liter scuba tank maintains its structural rating with regular use, so performance will not diminish after dozens or hundreds of refill sessions over the tank’s lifespan. For those divers who require a tiny, reliable air supply to grab and go, the 20 MPa rating puts true capability in the palm of your hand.

Aviation-Grade Aluminum 6061 Build for Corrosion-Proof Durability

The body of the 1 litre scuba tank is made of 6061 aluminum, the same alloy used in aircraft structures and marine hardware, where strength-to-weight ratio and corrosion resistance are non-negotiable. Saltwater, chlorine, humidity, and frequent wet-dry cycles will not pit or weaken this material as lower-grade metals do after a few seasons of regular use. That corrosion resistance is especially important for divers who carry their gear into the water, where exposure to salt is constant and unavoidable.

The breathing system is completed by a food-grade silicone mouthpiece that resists cracking, hardening, and chemical deterioration from prolonged exposure to saliva and seawater. The aluminum body and silicone mouthpiece combine to form a system designed to last for years of active diving. The entire kit weighs 10.89 lbs, including all accessories, and is light enough for one diver to transport, pack, and set up unassisted at any dive location.

Three Inflation Methods for Flexible Refilling Anywhere

The supplied manual high-pressure pump lets you top off the cylinder anywhere, on your own. It takes 800 to 1200 pump strokes to reach the full pressure, depending on how fast you pump, but that’s not a problem at a beach, lakeside, or isolated dock where there is no electricity or access to a compressor. This self-sufficiency is what sets the 1-liter diving tank apart from larger systems that are completely reliant on refills from the store or onboard compressor access.

The 1 litre scuba tank can also be filled with air from a standard air compressor or with a supplemental adapter that attaches to larger, compatible cylinders for a quicker turnaround. With access to the necessary equipment at a marina, dive center, or workshop, these two powered methods drastically reduce refill time. With three distinct inflation methods, your dive plans are never held up by a lack of a particular refill method, and the tank is always ready for your next use, no matter where you are.

Pressure-Regulated Vent System for Smooth, Steady Breathing

The constant flow of air underwater is not just a comfort factor; it also directly affects how comfortable and safe a diver feels at depth. This tank has a built-in pressure-regulated vent mechanism that dispenses air at a steady, uniform rate regardless of how full or empty the cylinder is. That regulation prevents the surge-and-drop airflow pattern that unregulated systems can produce as tank pressure drops during a dive.

Divers will also breathe steadily, which lets them get the most out of their air supply, potentially extending the 15-20 minute supply toward the higher end instead of burning it all in a panicked, uneven breathing pattern. The regulator adjusts automatically during the dive, letting you focus on the water around you instead of your gear. This consistent, hands-off approach is especially helpful for new divers, since it removes one of the major causes of tension underwater and allows the diving experience to seem natural from the very first breath.

Compact 1 Litre Scuba Tank with Carry Pack Sack for Easy Transport

The supplied carry pack fits around the cylinder, protecting it from scratches, dings, and other surface damage during travel and handling. An unprotected aluminum tank placed into a bag or the trunk of a car can quickly acquire cosmetic and functional damage. The packsack also makes it that much more convenient and orderly to tote the whole kit about, putting the tank, pump, and accessories into one grab-and-go bundle.

The cylinder itself measures just 3.50 inches in diameter by 14.17 inches in length and fits in a daypack, boat locker, or carry-on bag. Its portability lets you get to dive sites that full-size tanks can't reach, from remote island beaches to highland lakes where lugging heavy gear is a hassle. This 1-liter diving tank is as portable as a water bottle, yet it is a real underwater breathing system that will go anywhere your next adventure takes you.
