Three power supply methods:
▪️  AC Power Supply- Home/Hotel/ Office/ Indoor Use
▪️  DC Power Supply-Use in the Car
▪️  Extra Battery- Outdoor Use


1. Portable Design for Outdoor Use
This oxygen concentrator is lightweight at 4.85 lbs (2.2kg). It comes with a versatile bag that can be handheld, carried cross-body, or over one or both shoulders, adding more convenience to provide a reliable source of oxygen on the go. Great for the outdoors, plateau use, car use, and more.


2. Large Removable Battery
The portable oxygen concentrator is powered by a 6400mAh/92Wh long-lasting battery that can run for 3-4 hrs. Effortless removal in just 3 steps: 1) lay the product flat 2) pull the trigger, and 3) slide the battery toward the arrow.
An 8-cell battery will give you up to 3.5 hours of battery life, or an extra 16-cell battery to provide 6 hours ( Click here to get extra batteries.)
Two Steps To Remove The Battery.


3. Dual Oxygen Delivery Modes
This device has 2 oxygen delivery modes: Pulse Mode delivers oxygen by sensing the user's breathing rhythm, while Continuous Flow supplies oxygen at a fixed frequency. The 2 modes switch automatically according to users’ breathing patterns, suitable for a broad range of people.
The dual-mode oxygen concentrator NT-02 is an innovative and effective way to provide oxygen therapy to patients. Compared with the only continuous flow oxygen concentrators, the dual-mode NT-02 saves more battery power, which means users can use it longer without draining their batteries. The dual-mode oxygen concentrator can also produce oxygen for 1.5 seconds without detecting the user's breathing, Compared with only a pulse flow oxygen concentrator, it is easier to obtain oxygen for users with shortness of breath or shallow breathing.


4. Stable Oxygen Concentration
This oxygen machine outputs oxygen at a high and constant concentration of 93±3%. The flow rate is easily adjustable between 1-5L/min, allowing you to regulate the amount of oxygen you receive based on your needs.

5.
 Clean Oxygen Supplement
Our home oxygen concentrator features a high-quality CECA molecular sieve and undergoes a rigorous self-filtration process to purify oxygen before being finally delivered to users, ensuring every breath you take is pure and clean. 2 filter pads are included for easy replacement.


6.
 Restful Oxygen Therapy
An auto shutdown timer on the oxygen concentrator machine allows you to set a time interval between 1-240min. Moreover, it can be conveniently used overnight while plugged in, ideal for anyone requiring oxygen therapy during sleep.

7. Intelligent Alert System
Our oxygen generator has an advanced built-in alert system, providing real-time alerts for low battery, no breath being detected, low oxygen concentration, or high temp. This offers peace of mind to stay in control of your oxygen therapy process.

Squeaks break immediately
Color: 12 Tennis Ball
Squeaks break almost immediately, even with very light chewing. Some are so badly made that the squeaks break after one or two squeezes. Get Kong balls instead.

Nice balls but arrived with a bad chemical smell
Color: 12 Tennis Ball
Wonderful Product!!! The balls themselves are amazing and the squeaker in them my dog loves. I am giving them only a three star because they arrived and they SMELL like chemicals so bad!!! I was afraid to give it to my dog so i washed one out and put it up hoping the chemical smell will go away. This not good for a dog as unknown chemicals can make them really sick. Whatever amazon is spraying on their stuff it's not good

Puppy tested & approved
Color: 12 Tennis Ball
I ordered these squeaky tennis balls for my cocker spaniel. She absolutely loves these tennis balls with the squeakers in them! She plays with them all day, and chews on them frequently. We have not had any problems with her, breaking the tennis balls, which is generally the issue we have with her. The tennis ball fuzz stays on the ball very well, which is usually an issue with standard tennis balls, because my dog likes to peel off the yellow fuzz on all tennis balls. She has not been able to do that with these. I will definitely be buying these again , but will not need to anytime soon as these are extremely well built.

Dog toy that lasts.
Size: 5 Pack
I've got a heavy chewer on my hands, so I've basically thrown money away on countless "durable" toys that get shredded in minutes. I was skeptical about these, but the "no stuffing" design caught my eye—at least there wouldn't be fluff all over my living room! I'm happy to report that these have actually lasted! My dog loves shaking them around and making them squeak. The crinkle sound is a huge bonus; it really keeps him engaged. The fact that they're lightweight makes them perfect for a game of fetch, and my dog can easily carry them around. For the price, getting a whole bundle of these is a great deal. If you're tired of cleaning up toy stuffing, I'd definitely recommend giving these a try.
