## Questions & Answers

**Q: Q1: How long can this 0.5L mini scuba tank last underwater?**
A: When fully filled to 3000 PSI, the 0.5L scuba tank can provide up to 5-10 minutes of breathing air. Actual duration depends on dive depth, water conditions, and individual breathing rate. This tank is a backup air source, not a primary scuba tank.

**Q: Q2: Can beginners or non-certified users use this tank?**
A: No. This product is intended for certified scuba divers only. Proper training and knowledge of underwater breathing equipment are required to use this tank safely.

**Q: Q3: How do I inflate it?**
A: You will need a high-pressure air compressor capable of producing 4500 psi, and you will need to ensure the air is dry and clean. Using a high-pressure manual pump, it would take over 500 cycles to raise a 0.5L cylinder to 3000 psi.

**Q: Q4: Can I use a regular air pump or tire inflator to fill it?**
A: No. Standard air pumps, tire inflators, or low-pressure compressors cannot reach the required pressure and should not be used. Only professional high-pressure scuba filling equipment is suitable.

**Q: Q5: Has it been DOT certified?**
A: Yes, all UNAROWHALS diving cylinders have passed DOT certification before they are allowed to be sold.

## Customer Reviews

### ⭐⭐⭐⭐⭐ No Filling Instructions! - Update!  Seller Responded with Instructions and offered free adaptor!
*by S***E on July 10, 2024*

**Update** Seller responded with instructions and offered free adaptor so I can fill using my compressor. Great service here!Product is exactly as advertised and appears sturdy and pieces all fit as they are supposed to. I ordered the tank with the "Fill Adapter" which appears to be a way to attach the mini tank to a standard scuba compressed air tank.The instructions are limited and do not include any procedures to actually fill the tank. I have a hand air pump, which would take a considerable amount of time, and compressor, which should take less time, however neither of which can connect to this tank in any way.This product gets a two-star review due to the above, and the printed text: "If you encounter trouble during assembly or use, don't worry—we offer 24/7 technical support. Dive confidently knowing assistance is just contact us away." - Note that nowhere on the page, in the pictures, or in the documentation provided with the tank, is there any contact information. Phone, email, fax, or physical address are nowhere to be found. An online search only yields sites to purchase the same tank from other websites.

### ⭐ No instructions, very hard to use and fill.
*by E***S on June 28, 2025*

The media could not be loaded. I bought one in blue and my Fiancé got one in black. We got them back around Christmas and now that its summer we are trying to use them.Very confusing, doesn't come with instructions.Im pretty sure the black one is broken when you try and fill with air you hear the mouth piece hissing and the button doesn't release air. Plugged up the blue one to the compressor and its actually filling up but the mouth piece is also hissing and its taking a very long time to fill the valve goes up extreamly slow. Hopefully im doing it right since the are No instructions.
