Besides, the 8mm one-way valve of the scuba tank can connect the refill adapter to fill up. You need a bigger bottle to guide the vials. Also, you can inflate the scuba tank with a high-pressure hand pump. The last one, an electronic air compressor is a good choice which only takes you 8-10mins.
【5minutes usage time】The working pressure of the scuba tank is 200bar/20mpa/300PSI. The 0.5L mini pony bottle can be used underwater for about 5 minutes. A mini scuba tank can be used as a backup air source for a deep dive and emergency rescue can also be used to clean the boat and pool, underwater exploration with this small air bottle is also a very good choice. (The time of use will be affected by temperature, diving depth, and breathing rate.)
USING IT MORE SAFER: SMACO S400 pony bottle adopts constant pressure exhaust and explosion-proof device.The high-pressure gas in the bottle is decompressed and output through the decompression chamber,making breathing smoother and safer to use
RELIABLE AIR SUPPLY: The S400 1L scuba tank delivers approximately 75 breaths at 200 bar (tested at 16 ft depth).It incorporates a double-layer filtration system that effectively blocks dust and impurities, ensuring clean and reliable air with every breath
