I have an inogen one G2 system (24 cell battery) concentrator for sale. Its just under I year old. goes up to 6 litres a minute pulse flow. if you use it on 2 litres a minuit, you will get 7 hours use out of it. If you use it on 5 litres a minute you will get 4 hours use out of it.
It comes with a battery, carry case, shoulder strap, hand strap, trolly, car charger and mains charger (which you can use and charge at the same time) I also have a adapted black rucksack I used with it.
My conditioned has worsened and I am now on 10 litres a minute at rest, so the portable concentrator is no longer any use for me. It did for a while make me so much more independent and active. They are really good machines.
I paid £2995.00 on 24.02.15, I would accept £1400.00 or nearest offer.
Its in the original box with all the instructions and leaflets. I will also enclose a the original invoice, because of EEC laws purchases are covered for two years now.
I live in west London, it can be picked up, posted or couried which ever is preferred.
