At full capacity, this diving cylinder allows you to take up to 340 underwater breaths. This might vary depending on the temperature of the water you’re diving in and the rate at which you breathe.

You’ll also receive an intelligent high-pressure indicator air compressor. The air compressor allows you to set your ideal tank pressure. The fast inflation and automatic stop functions allow you to refill the tank while getting ready for your dive.


  • This tank allows you to take up to 340 underwater breaths and lasts for 15-20 minutes.
  • The air compressor has fast inflation and an automatic stop so you can leave your tank while you get ready for your dive.
  • The safe depth limit is 33ft or about 10 meters.
  • This aerospace aluminum scuba tank is long-lasting and resists internal corrosion and damage.


  • You can only use this tank in water temperatures above 10 degrees Celsius. This isn’t appropriate for cooler climates or natural lakes and rivers.

  • For non-experienced divers, the price point is quite high for a first kit investment if you’re scratching the surface with diving.

This backup mini scuba tank has a great price. We’d say this is the perfect investment for someone who knows they’re going to make use of the product. For first-time divers, we’d estimate this investment may be a little over their budget.

The Best Mini Scuba Tanks: Read This Before You Buy

We’ve given you the products, now let’s get into some of the nitty-gritty before you make your purchase.

What’s the difference between a mini scuba tank, and a regular scuba tank?

For the beginners amongst you, you may be thinking “why can’t I use these kits to dive regularly?” Well, the mini scuba tank has different capabilities than a regular scuba diving tank. 

This is because the amount of oxygen the tank can hold differs from the size and capacity of each tank. If you’re looking for something long-lasting to use for dives longer than 20 minutes in deep waters, a mini scuba tank is not right for you.

These mini tanks are only advisable to use for up to 20 minutes, depending on the individual tank and depth. This is usually around 10 meters, or 30 meters if you’re using it as a backup tank on a long dive.

A regular diving tank has a larger body and can last up to an hour in deeper waters. You will not have to worry as much about the tank’s pressure or capacity. 

If you’re looking to take a deep dive, or you’re a more experienced diver, you’ll want to check out a larger tank. These are offered in a variety of sizes, but the mini scuba tank will not provide the experience you’re looking for.

What are the benefits of a mini scuba tank over a regular tank?

Some benefits of the mini scuba tank outweigh the regular scuba tank, especially for those beginning their diving journey.

Some benefits include:

  • Lightweight practicality: it’s easy to transport, carry and store.
  • Quick oxygen filling: if you have an electric air pump, you’ll be ready to dive in no time at all.
  • Fitted with gauge meters: you’ll be able to tell how much diving time you have when you’re in the water for peace of mind.
  • Comfortable, silicone mouthpieces: like the SMACO Mini Scuba Cylinder, which make diving an ease.
  • Lower price points: you can try diving at a fraction of the price of a full-blown diving kit.
  • Refillable design: you’re going to be able to use this product again and again, making it worth your initial offset.

How should you use a mini scuba tank?

Mini scuba tanks were originally designed as backup tanks for scuba divers in case their main tank failed. Most can be safely used for diving within a depth of 10 meters. 

If they are used as a spare air source, then they can be used at a depth of 30 meters maximum. Mini scuba tanks are not meant for deep water diving.

Nowadays, mini scuba tanks are used more recreationally for beginner divers that do not want the expense of investing in a large-scale kit. 

While this is a great idea for novices, it does take a while to fill up a small tank by hand, and it is gone in less than 20 minutes.

Be mindful of how and when you want to use the mini scuba tank. If you get to the beach and the tank is not full, you’re going to spend a long time getting it filled without an electric air pump.

How far can you swim with a mini scuba tank?

This all depends on the speed at which you swim. On average, you could swim as far as 100m in length with a mini scuba tank. Check out Christian Wedoy’s YouTube Video on how far he managed to swim with a mini tank.

What are the different scuba tank regulators?

The mini scuba tank kits we’ve suggested come with universal mouthpieces. These are one-size-fits-all mouthpieces designed to fit everyone. 

There is a range of different regulators available to fit your diving plan. There are regulators made for different temperatures, locations, and your mouthpiece preference.

Check out this video to learn about exhaust values, purge buttons, and how to choose your first regulator.

What are the common differences between these mini scuba tank products?

The key difference between the mini scuba tanks is the materials used, such as steel or aluminum. The amount of air the tanks hold, and the depth at which you can dive.

The tank with the shortest dive time is the SMACO Mini Scuba Cylinder, as it only allows for up to 10 minutes of dive time. The other four products listed all have similar capacities of 15-20 minutes of dive time, but they have different materials and perks. 

The SMACO Scuba Tank Diving Equipment comes with an air compressor, which makes for quick refills. The DEDEPU diving portable tank offers a lightened pressure gauge so you can see underwater how much time you have left.

Each tank offers something different, so it all comes down to personal preference.

The Best Mini Scuba Tanks: Commonly Asked Questions

How long does it take to fill a mini scuba tank?

Depending on what pump type you’re using, and what the tank capacity is, depends on how long it’ll take to fill your mini scuba tank.

A manual pump is going to take significant time to fill your dive tank because you will be required to pump the air into the tank itself. It’s going to be a long-winded process that will use your energy up for sure. 

Check out this handy video on how to fill up your scuba tank with a hand pump here.

It’s smart to invest in an air compressor or electric pump that quickly fills your tank without needing to put in any physical labor.

The SMACO Scuba Tank Diving Equipment comes with an air compressor and a hands-free option for filling your tank. This is great for multitasking while getting ready for your dive.

Are small scuba tanks safe?

Mini scuba tanks are safe if you ensure you follow the safety precautions and warnings given by the product and brand. Ensure you read through all the instructions when you buy your scuba tank and take a look at some top tips for beginners. 

How long can you stay underwater with a scuba tank?

This relies on the scuba tank you choose. Depending on the capacity of the tank will depend on how long you’re able to stay underwater. The average for mini scuba tanks is around 10-20 minutes. 

Some of the lightweight ones, such as the SMACO Mini Scuba Cylinder, only last 10 minutes.

Your requirements will determine which scuba tank is best for you. Make sure you do your research before you decide because each tank will have different limitations.

Can I fill a scuba tank with a hand pump?

Yes, all scuba tanks have a universal connection inlet, which allows you to fill it up with a hand pump, a compressor, or a filling station.

It’s going to take you a while if you’re using a hand pump because you’ll be manually pumping the air into the tank. This could be very time-consuming depending on the size.

We recommend investing in an air compressor or electric pump, so you can multitask while your tank fills up.
