Overall rating: 4.5 / 5 from 31 reviews.
I bought this hoping to make trips out a little simpler. It takes some planning to pack everything and keep the battery charged. Once I'm ready, it's manageable, though I wouldn't call it effortless. Three stars feels fair. A clearer quick-start guide would have made the first week less frustrating.

The battery rating caught my eye when I was shopping. I still charge it before an outing and check the level before we leave. That's worked well for my routine. Happy with the size, too; it doesn't take up half the living room.

Good
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
It fits in our small car without much fuss. Getting everything packed and ready takes a little time, though. I wish keeping the cords organized were easier. Nothing serious, just one of those things you notice after a while.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
Fits nicely beside my chair and is easy to move.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
I'm happy with it around the house. Carrying it for a longer stretch is less comfortable than I hoped.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
It's so convenient to get around, and I don't have to worry about breathing problems anymore. I can carry it around, walk, breathe oxygen, and drive at the same time. I've been using it for a week now.
Portable 1-5L Adjustable Pulse Flow 4 Hours Battery Oxygen Concentrator - DF-012BX
I rarely write reviews. This is my first portable oxygen concentrator. It's very light, though a bit heavy with the battery. It's compact, and the backpack it comes in is also very useful.
Portable 1-5L Adjustable Pulse Flow 4 Hours Battery Oxygen Concentrator - DF-012BX
I would like to buy an additional battery.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
The price is very affordable—thank you.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
Very light, very small, and also a bit noisy.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
We take it with us every time we go out by car—it’s incredibly useful.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
I'm retired, and most outings are ordinary things: groceries, visiting family, sitting on the porch. I wanted one oxy machine I could work into that sort of day. So far, I've been very pleased with my choice.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
I like having a portable option, and it suits the shorter outings I usually make.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
A sensible size for our little place. Easy enough to move around, though I wouldn't want to carry it all afternoon.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
I’ve always used the 1-liter size; it lasts a long time.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
It's okay overall. I like being able to take it along, but the sound is more noticeable than I expected when the house is quiet. That part has taken some getting used to.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
My wife and I went through the directions together at the kitchen table. Some parts needed a second read. Once we had a routine worked out, things went much more smoothly. I can get it ready myself now, which was important to me. A few better pictures in the booklet would help.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
I like that I can get it ready myself. A small thing, maybe, but it means a lot to me.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
Not silent, but the sound doesn't bother me much during the day. It's more noticeable when I'm sitting quietly with a book. Otherwise, I've found it convenient to move from one room to another.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
No bells and whistles needed. I learned my way around it pretty quickly.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
The machine is fairly easy to use. The instructions could be clearer, especially for someone setting one up for the first time.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
My hands aren't as steady as they used to be, so getting comfortable with the controls mattered to me. A few practice runs helped. I can manage it now, but clearer instructions would have saved some frustration.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
Good for my usual errands. I charge it before leaving, and I keep an eye on the battery instead of assuming I'll get the full five hours every time.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
Easy to use. No complaints.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
I don't need anything fancy, just something I can manage myself. This has been fairly straightforward, although the first setup took me a while.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
I'm in my seventies and didn't want another gadget that needed my grandson to explain it every time. We went over everything together once, then I practiced at home for a few days. I can manage it on my own now.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
Does the job, but carrying it gets tiring on longer walks.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
I like it, but you do have to think ahead about charging. Forgot once and had to change my plans. That's on me, really. I've started keeping it in the same spot each evening so checking the battery becomes a habit. Much easier now that I've got a system.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
Pretty good. Wish the booklet had larger print.
DF-012BX | 1-5L Pulse Flow Portable Oxygen Concentrator with 5-Hour Battery
The doctor allowed us to be discharged and go home for treatment. We not only bought a ventilator and a large oxygen concentrator, but the doctor also recommended this small oxygen concentrator for my mother. When the weather is nice, I can take my mother out for activities, and she's in a much better mood.
