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. ### ⭐⭐⭐⭐⭐ Amazed *by on Reviewed in the United States April 15, 2026* 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. ### ⭐⭐⭐⭐⭐ Todo perfecto *by on Reviewed in the United States August 14, 2026* Todo perfecto buena calidad ## 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.jp/products/268488613-smaco-s400-mini-scuba-tank-1l-portable-diving-lung-air](https://www.desertcart.jp/products/268488613-smaco-s400-mini-scuba-tank-1l-portable-diving-lung-air) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-28*
