0.5L Mini Scuba Tank, Portable Refillable Diving Tank for Underwater Breathing Training, Up to 10‑Minute Dive Time (Up to 33 ft), Spare Air Scuba Tanks

I bought this for my son's birthday, he loves it, is a pretty cool buy. However,it takes about 20 mins to pump up to 150 psi, and it's a work out and a half. I hate having to pump it up Everytime. I'm hoping I can find a faster and easier hand pump for it.

El tanque sirvió perfectamente en varios entornos acuáticos que lo usé, tanto en piscinas como en el mar. La bomba manual se demora en cargar el tanque unos 20 minutos sin parar, algo cansado pero es algo de esperarse. El adaptador para el tanque grande funcionó a la perfección también.

I love how small and portable this mini tank is – perfect for my casual dives! I just throw it in the car and take off for the beach. The storage bag is awesome, keeping everything organized and easy to carry around campus. It's a super cool way to get a taste of diving without lugging around a bunch of gear.

It’s a fun toy but not worth the effort to pump up the tank for quite some time

Not suitable for regular diving, but it's incredibly useful to keep on the boat as a spare for emergency situations.

This is a well-made, narrow silicone mouthpiece. It easily fits my second stages and comes with good quality zip-ties. It is comfortable and the pattern/texture makes it easy for my teeth to hold it in place and create a good seal. It is easy to clean.

This mouthpiece is made of a sturdy yet soft material, making it very comfortable to have in mouth. The size is perfect, and it fits well with different types of breathing tubes. The seal is excellent, ensuring it is very safe and reliable to use.

This is amazing produst. When I put the soft mouthpiece between my lips, I felt the comfortable fit and seal, and at the same time, I breathed in fresh oxygen through the respirator, and I felt the ease and comfort of swimming underwater. This allowed me to breathe easily underwater and enjoy the fun of diving.
