Portable Oxygen Concentrator 3 L Compact Continuous Oxygen Machine, 35% Battery Powered Oxygen Generator AC110-240v 3.3lbs

Very nice and quiet my fan is louder works great especially when sleeping I wear like a head band so it comes off if I roll over in my sleep never had a issue yet

The machine is louder than I assumed from description. The carrying case is a bit heavy. Machine works well, the cannula that came with it is uncomfortable. But other than that I'm satisfied.

Be careful when you purchase! The price fluctuates horribly! One minute it’s almost $500 the next (AFTER PAYING) it’s $278.99! Amazon refuses to cancel the order! You’re forced into keeping it! They give false information when trying to get help! Item didn’t ship until Yesterday (Monday evening) arrived Tuesday afternoon! Item does not specify if it needs filters etc. Extended battery does NOT last as long as mentioned! It weighs MORE than 3 lbs. The oxygen hose is extremely short in length so doesn’t even reach from the nightstand to the bed without the machine falling off! Between customer service, their supervisors and the price gouging and an item that was shipped to me “USED” I’m extremely EXTREMELY DISAPPOINTED! The box it arrived in was “taped again” a different mailing address under a sticker! So it was not new! It was opened and sealed and shipped back! As I was informed was NOT Allowed! BEWARE!

This product allows my husband the freedom to be out and about.Our only problem is he likes to be out longer than the battery allows. We need an additional battery.

Wanted it for my husband for home use. It’s ok, works as described, butmachine is loud. Can’t even think about taking a nap or watching TV. It may have to be returned.

Bought this for my dad, who requires supplemental oxygen, the compact and portable design of this device was a game-changer for him. Weighing only about 3 lbs and coming with a convenient carrying case, it's incredibly easy for him to take it wherever he needs to go.The built-in battery of this portable oxygen machine lasts for about 2 hours when fully charged, which provides him with a reliable source of oxygen on the go if needed. It gives him the freedom to attend social events, go for walks in the park, and even travel short distances without worrying about running out of oxygen.Using it was a breeze. The controls were straightforward, and the interface was intuitive, making it user-friendly even for someone who is not particularly tech-savvy like my dad. He found the device to run quietly, which made his experience even more comfortable. If you're someone who requires supplemental oxygen and values mobility and ease of use, I highly recommend considering this device.

The lighter power cord is too short and it is too noisy for say a nice restaurant. But for driving and observing sports it does the job. Bought a 5 1/2 foot cord for $13.

I bought this oxygen concentrator for my father. He needs oxygen when driving. This portable oxygen concentrator can be plugged in using the vehicle cable, which is just what I need. Moreover, it has rechargeable battery, and it's lightweight. My father now can carry it when walking.The oxygen it generates is fine. It can stably output the oxygen with the concentration of 32%. Overall, it's easy to carry around and use. It meets our requirements. My father likes it.
