Use a scuba adapter to introduce compressed air from the big cylinder into the scuba tank, which can be filled in just 10 seconds. It takes about 26 minutes to use an HOUVAN air compressor.The manual pump takes about 50 minutes to inflate, which is quite laborious and is recommended as a backup.The working pressure is not more than 3000PSI/200bar/20Mpa. 【Applicable multiple scenarios】 The HOUVAN S400 scuba tank can be used as both a beginner diving practice and a backup source for professional divers.

Great for quick underwater exploration or backup use. Feels well-built and reliable. ### ⭐⭐⭐⭐⭐ Get that compressor. *by B***H on 8 June 2025* The tank is awesome. We love it. We will likely purchase more. You need the small air compressor. Don't even try it without one. ### ⭐⭐⭐⭐⭐ Great when getting into scuba diving *by T***D on 9 September 2024* I want to get both my younger son and I into scuba diving. I want to make sure my son likes it before spending the money on a course to get certified. This mini tank is just perfect. I only needed to attach a few items and the tank was ready. I did find the certification info for the tank and it's dated 9/23. I ended up taking the tank to the dive shop and had them do their certification and fill up. It passed and we started with 2500psi. The tank is rated for 3000psi. We took turns using the tank at the pool and he loves it. Took a few minutes to get used to the breathing. We got about 10 minutes of run time. We don't have an air compressor for this tank so for now we have to spend the money to get it filled. I'm just excited the tank worked, the mouthpiece was easy to use and adjust and most importantly, my son enjoys it and is excited to take the class. Very nice product and the tech at the dive shop was impressed as well. --- ## 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/628494201-h400-diving-tank-1-0l-diving-tank-holder-15-20](https://www.desertcart.jp/products/628494201-h400-diving-tank-1-0l-diving-tank-holder-15-20) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-17*
