InogenExternal Battery Charger for Inogen One G5/Inogen Rove 6-0.12 lbs. and 3.13 in. W x 2.75 in. L x 1 in. H

The first one I bought the cord was broken. When I returned it and ordered another one, it has worked like a charm. It is helpful at times to be able to charge one battery while using the other. It was definitely worth the money.

I have a fear of power blackouts. With this item I can have my three batteries charged and ready.

Was doubtful upon receipt of the charger as it appeared somewhat small for both the job and price. As it turned out, the charger was a bit slow but performed very well.If someone has a few extra buck to spend on an emergency backup charger, I would suggest they git it a try.

Very easy to plug in and charge extra battery. Gets full change. Easy hook up and disconnect.

This external charger is a bit on the expensive side. It should also come standard with the Inogen portable unit. It is needed because the batteries last only so long, so you need backup batteries and on longer trips you need to charge the exhausted battery up. It works fine, but the cable jack that plugs into it is weak. It slipped out of the socket several times on my first try to charge up the second battery. The older charger for the G3 unit is a snug fit by comparison. By the way, the picture without the AC to DC converter is misleading. Also interesting that for the G6 version you can use the G5 charger. I needed to research that a bit before I spent money on it.

I need my inogen one g5, so I bought a larger battery. I also bought external battery charger for it. It is so simple to use, push in the battery and let it charge. Gives me peace of mind on stormy nights and longer then usual doctors appointments. Very happy with the external inogen battery charger.

This charger works faster than expected. I am very pleased with it.

Great battery for Inogen 5.
