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 of battery life( 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, which is 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, which is 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.

Comfortable Shoes Right Out of the Box
Size: 9, Color: Black
I bought these shoes for my husband. He has a very hard time finding quality, comfortable shoes. These shoes are just as comfortable as his New Balance. He uses them as a dress shoe and wears them at least once a week. There was no break in period necessary. They were comfortable right out of the box! The only thing we didn't like was the white sole color. Once I knew he was going to keep them, I used a black sharpie marker to color the soles black. Instant amazing, comfortable dress shoes. They were well worth the cost. If you or your SO needs a comfortable pair of shoes, we highly recommend them.

Paid for new, received used.
Size: 9.5 Wide, Color: Cognac, Size: 9.5 Wide, Color: Cognac
Arrived dirty as if someone whore it for more than a few days. Maybe I was mistaken, but I saw nothing about “previously used” on the Amazon page. Returned it. I would suggest that the company use quality control when it comes to shipping. The shoes seem find otherwise. I ordered 9.5 and it was just a bit tight. If I reorder I will go for size 10.

Decent Shoes with Misleading Description (Not Leather)
Size: 12 Wide, Color: Black, Size: 12 Wide, Color: Black
I only look for leather when I’m purchasing dress shoes. Under the description “details” on this item it lists the shoe as leather upper and inner lining. A photo shows “genuine Napa leather lining”. If you keep reading (which I have now that I’ve received the shoes) it shows “faux leather” in the small print and that is not “leather”. I run a small leather business and this irks me because it’s clearly false advertising. The details also show the product is made in Brazil but when they arrived today, the shoe tag shows “Made in China” and “Man Made upper and lower”. I don’t hate the shoes. They look nice. What I know is they won’t hold up over time like leather, which is why the description should be accurate and not misleading.
