Heavier & more cumbersome than expected
By PATRICIA B.
Have had occasions when one or the other battery wouldn’t register as full when definitely was full when I was on a cruise. So I had to sit in room until other battery charged. Batteries don’t last as long as expected.

I have had the G3 for about 2 months now and find that when it is not in use the battery runs done about 25-30% in 2 days of not being used. Also the unit needs to breath on both sides and when carriing the G3 it can only breath on one side and it becomes kinda hot.

I have been with Inogen for a number of years now. Representatives are always professional and I love the fact that my portable is FAA approved. I don't have to wait a long time when I order supplies or something goes wrong with my concentrator. Currently I am on 4 liters. I wish you had a portable that's a little lighter weight and last longer than 5 hours.
