While using tanks I was always worried about running out of oxygen. It happened a few times and was very scary. Gulping for air is not any fun. Now I have a portable Inogen unit and it's battery last a long time. On my trips to the doctor I use the power cord in the 12v outlet and it keeps my battery charged.

The Inogen "At Home" is the smallest, quietest, and best made free standing model on the market. PS: I'm an electrical engineer.
I'm NOT a "portable" Inogen user, but I am a long time sleep apnea sufferer who needed supplemental O2 combined with the use of my BiPap machine. Luckily I had the means to purchase my own Inogen "At Home" O2 concentrator rather than use some cheap, large, noisy, piece of crap, rental concentrator that Medicare was going to set me up with. NOTE: Medicare only pays part of the rental costs and they stop paying all together after 3 years. I did have to get a prescription and testing results from my Doctor for Inogen.

So far, we're very happy with the purchase of the Rove 6 oxygen concentrator. It has delivered the extended battery life we were hoping for making it much easier to stay away from home for longer periods of time. Hopefully it will continue to deliver these same results over time.

Charging the battery
Machine works like it should although being a pulse operating machine it does not give you the oxygen like a constant flow does . It's stupid that the battery has to be on the machine to charge it ! You should be able to charge them by themselves so while using the machine you can have another battery charging for when you need it !!

The small one that I take outside i wish could be lighter in weight and last longer before needing charging other than that they are working real good

I received the in home and portable concentrators in the mail through my medical clinic. What a surprise. The in home unit is super quite. The portable concentrator is such a relief from the cylinders. Now I can take my dog on a proper walk, grocery shop and do my laundry with ease. Plus Inogen sent a box of hoses and canulas without asking. I am very happy with the equipment and Inogen.
