Had doctor verify that wife’s oxygen level was 85 or lower. Submitted paperwork to our oxygen company, they did some magic with Medicare, it took approximately three weeks for Judi to be tested for compatibility with the pulse generator. Came with car charger (12 volt), wall charger (120 volt), carry bag w/strap, and backpack. Weighs 5 pounds. So much easier than toting bottles around.

I have a portable pulse concentrator that weighs only 5 lbs. I had to pay for it out of pocket but I understand Medicare and insurance may pay for them now. It even plugs into your car cigarette lighter while traveling if it needs recharged. I use it at home also rather than the large concentrator I have because it makes my electric bill go out of sight!!

I've had an Inogen one G2 for almost 7 years. I've bought extra batteries as I've gone on because they wear out. You can get a car charger for them, and a wall charger. I travel all over the country with mine constantly. I'm on oxygen 24/7.
I bought mine, $3600 with a lifetime guarantee. They've fixed it 3 times. Hey will usually overnight a replacement to you, so inconvenience is kept to a minimum .
$3600 seems like a lot of money, but so many people spend that much per year just on cell phones and cable TV. If you don't have $3600 use a credit card. You could pay it off in 3 years for $100 a month.
A small price to pay for you freedom .

I live in a RV, I have no tradition home. I am on the road 9 months a year, and camped around my home town for 3 month. I have a full size concentrator and my Inogen concentrator. I'm enjoying life with $25% lung function. (I'm 68 years old).
Any questions contact me.

I have an Inogen One G3 I take with me. Can be charged in the car or on 110 volts. Your doctor will help you get one going through Medicare... The newer ones out will go to 5 liters... Hope this helps. For all nighters, I take my home unit.

I am on 8 liters of oxygen and Imogen told me I can't get a portable that high so I take my regular tanks when travelling and use my concentrator when we stop overnight. I also make sure there is an oxygen supplier near where I am going.
