COXTOD 1-5L/min Portable Adjustable Oxygen Concentrator for Travel use,with 10000mAh Lithium Battery for Home and Travel Use, AC 110V Humidifiers

My last oxygen machine stopped working so I searched on Amazon and purchased this unit. The tube smells too bad when I unpack the accessories, it makes me unhappy and throw them immediately. I tried to use the machine because I really need it, it is much worse than my old oxygen machine. Oxygen OFF AND ON, which made me feel uncomfortable. Also Doesn't work after use few days, it was awful!!! The machine seems nothing helpful to me, totally a waste of money.

This concentrator does not work in the car

I like the easy way this travels with just a plug in the cigarette lighter for as far as you want to go. But it is bulky and heavy to pull around behind you and the battery runs out quickly at 5 L. You need a lot of batteries if you plan to be out very long.

I got this for my mother to use when traveling (she uses a regular oxygen machine at home). This machine is quiet, lightweight and works well. She really likes the soft tubing.

excellent product and attention

Great team, the seller offers great attention, the product has a very good relationship in terms of price and quality, it is worth buying, they have all my needs.

UPDATE!! We had to use this unit after a seizure and it worked great!! It does take 10 minutes to come to full purity. BUT, the oxygen supply company that we were using said all concentrators take 10 minutes to come to purity so if you get an “emergency” need you should have a tank at home and use that for the first ten minutes while your concentrator is coming up to speed. I wish someone had told us this information years ago!!! The oxygen supply guy was very impressed with this unit!! We ran it for 90 + minutes with no issues and good results. The manual does explain the ten minute prep time too. We love this unit and will buy another one. Thanks for such a great product!

A little heavier than the heavy advertised oxygen concentrator, but much cheaper. Not suitable if oxygen is necessary to maintain life, but a suitable supplement.
