DEDEPU 2.3L Scuba Tank, Mini Diving Tank Small Lung Tank with Adapter, Up to 40 Mins Underwater Breathing Time, Portable Backup Air Cylinder, Emergency Resuce Pony Bottle

I picked up this 2.3L mini scuba tank as a backup air option, and honestly I’m really happy with it so far. The setup was straightforward right out of the box and everything went together easily without any confusion, which is always a win when you’re dealing with crucial gear like this. Once filled, it held air perfectly with no leaks, so it gave me peace of mind knowing it’s reliable when you need it. The portable size is one of my favorite things about it. It’s compact enough to carry without feeling bulky, but still holds a decent amount of air for short dives or as an emergency backup. The build quality feels solid and well made and not cheap or flimsy at all, so in my opinion it was a terrific value for the price. Overall, this is a great little tank to have on hand, whether you’re using it as a pony bottle for extra safety or just want something portable for quick underwater tasks. It does exactly what it’s supposed to do, and isn't going to leave you hanging.

Nice portable set for quick recovery of lost items or shallow beach combing. Assembled quickly and I used one of my larger scuba tanks and the provided adapter to put some air in and went to about 1000psi. I only hand tightened everything and did not have any leaks. The box it came in is nice for storage and transport. Keep in mind it must be fully disassembled to fit in the box. This will be a great little set for the boat in the spring. Things to consider: The first stage is integral to the tank so once pressurized you cannot take disassemble and the gauge will stay pressurized. There is no form of buoyancy compensation. This must be done with other means. The regulator breathed easy on the surface. I'll add to the review once I try it out in the warmer water. Personally would not recommend to any person that is not a certified diver due to inherent risks of diving sport.

Hard to fill in the air and after all it was leaking somewhere couldn’t hold the air inside the tank never make it to the ocean maybe that one was damage but won’t buy it again

This little kit is so convenient for any diver. We have lots of springs here, and I’m super excited to use this on short dives. It’s compact and easy to store. I didn’t realize it came with a lockbox to store it in, which only makes it even easier to store and more portable. It’s carry-on size to take with for travel.

This thing does not allow us to put air in it the way y'all say it does.
