Oxygen Generator 3L Portable Oxygen Concentrator for Travel Use 33% Oxygen Machine for Home/Car Use with Complete Accessories

Works great. I read the review from the Red Cross and decided to give this a try. I also bought 2 of the extra larger batteries. It comes with 1 battery, good for one and half hours. However buy 2 of the bigger batteries and they are good for 3 hours each. Very happy with this as it gives me 10 hours running time. It comes with a car battery which will maintain the battery that is plugged in. It also comes with an outlet plug which will re barge your battery. Not really heavy, maybe 7lbs. Just not sure on weight cause I carry all 3 batteries in the pack. The bigger batteries are moreexpensive but for peach of mind well worth it.UPDATE : the machine itself got really hot on an overnight trip. Hot enough I had to just turn it off and sleep without my oxygen. Was great for the day but would suggest don’t use on along overnight stay.

I’ve been using this at home and in the car recently, and it’s been working well. It’s compact enough that even when I grab it for short drives, it doesn’t take up much space inside the vehicle. I usually keep it running on the 2 L continuous-flow setting, and the output has been steady and comfortable. It only gives off a soft hum, so it doesn’t interfere with conversations or background noise. The battery doesn’t last super long—just a little over an hour, but for longer trips, I just keep the car charger handy and recharge it on the go.

works as advertised, unit does get hot, especially when its in the carry case, the unit case should be better ventilated, as should the carrying case.The included canula is very stiff and horrible.

Do not order this product. It worked good for a couple times and now it doesn’t hardly work at all.

The oxygen generator is great for my mother-in-law. I got her a new one since she left the last one in the airport; no big deal.I decided to order this one since it's portable, very convenient and easy to travel with. It is lightweight and perfect for her to carry, and it comes in a portable bag for easy traveling and storage.The noise level is pretty low; it won't bother anyone or be annoying. It has great battery life, so she can use it while she's away from home and no electricity is available.It's a pretty good oxygen generator, and it's good quality for the price. I feel happy and secure while my mother-in-law has it.

works as seen. husband able to use as he walks

Very good product I recommend it a lot it is super practical and very easy to use.

So far I have used only once when electricity was off during a storm. I like that it is continual and not intermittent puffs of air. It is a little odd in that the battery plugs into the machine instead of attaching to the machine. This is not a machine that you can set down and walk around while using because of limited length of air hose. Portable only. I am not sure how long it will hold a charge while in operation. I suppose in extreme circumstances a person could use continuously if the battery charger stays plugged in during use.I got this to supplement the oxygen concentrator that I use regularly . I would buy again.
