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

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.

High quality item for quick dives into the water, everything fits and works as intended. Normally it will last me about 6-10 minutes under water. I would generally only use this for a snorkeling aid or very shallow dives. I prefer this one over the smaller tank because I’m able to check the air I have left without taking the mouth piece out.

Got the tank, tried it in the pool. Here is a quick review. It worked well in the pool, the regulator and tank functioned as it should. However, there are a few things that need to take notes of. First of all, it does NOT give you 20 minutes of air, not even close to. It's a 1 Liter tank, which is about 1/10th the size of a regular 80cf diving tank, so it basically gives you 1/10th of whatever your breathing time is with a regular diving tank. I can usually breath 60 min with a regular tank in a dive, so no surprisingly, this tank gave me about 6 minute +/- of breathing time. Also, if you do not want to invest in an electric pump, do NOT buy it. I used my PCP electric pump to fill it up and it took almost 20 minutes. Simply can not imagine pumping it with a hand pump, it may take you whole day to fill it up. And despite what some of these tank sellers claim in their pictures, this is NOT for beginners. Do not try to play with this out in the wild if you are not a certified and experienced diver. I'd only try to use it in very shallow water like no more than 10-12 feet deep, where I can make to surface right away in any emergency.

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.

The SMACO Scuba Tank is a compact and portable diving solution, ideal for short, shallow dives or emergency backup air. It’s lightweight, easy to refill with a hand pump or adapter, and convenient for travel. The build quality is solid, with durable aluminum construction and a user-friendly design. However, its air capacity is limited (typically around 10-20 minutes of dive time), making it unsuitable for deep or extended dives. While it’s great for snorkeling, pool training, or emergency use, serious divers will need a standard scuba setup. Overall, it’s a fun and practical gadget for recreational use.

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.

The tank and first stage are built solid, but the 2nd stage is crap. You got to huff and puff to get any air out and thats on the most sensitive setting.

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.

Worked perfectly

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 !

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