VHBW 19V Charger Compatible with Inogen One G1 G2 G3 G4 G5 ADP-120RH BA-301 BA-302 BA-303 Concentrator, 120W 9.8Ft Long Power Cord Compatible with Inogen

No problem works perfect with my portable oxygen concentrator I have a Imogen

I'm leaving one at the office and the other one at home, since I have 55 miles to travel each way, each day. Nice not to have to carry my charger.

I have an Inogen G4 and another inherited from my late brother. The other no longer works, but I use it as a battery charger. This is a spare, and another for traveling so I can plug the Inogen into a hotel wall when traveling. I bought a fourth as a gift to a friend whose power supply had failed His budget was tight. Works just fine and is less than 20 percent the cost of the Inogen unit, which has identical input and output to this. I have three extra large batteries so I can travel freely with up to 12 hours of O2 as the airlines require.

Like original from manufacturer. Reasonable price and perfect condition. Is working very well.

Works great for portable breathing machine and way cheaper than company product. Charges battery fast and easy to use.

Well-made and gets the job done

Good

Works as advertised.
