Always plug the DC adapter from the Inogen One G2 to the cigarette lighter up front in the vehicle, not the power supply in the back seat. The reason behind this is the other cigarette lighter plugs are weaker than the front plug. The other cigarette lighter ports in the vehicle may not be strong enough to operate/run and charge the battery on the Inogen One G2.

    A friend of mine passed and her family was kind enough to sell us her machine for my son's use. I have a couple of questions if you wouldn't mind helping me. There is a part I don't know what it is used for. Also how long should I charge the batteries after they've been stored for awhile.Thank you.
