Stand alone battery charger for InogenONE G2

[bazwag]

I am looking for above stand alone charger for a single Lithium battery for Inogen One G2 portable concentrator.

I have an Inogen concentrator, and I have found that a standard (19 volt) laptop charger works fine charging the battery in the Inogen. I believe the genuine stand and charger costs about £200.
