Inogen G5 / Rove 6 External Charger (BA-503)
Keep moving with continuous power rotation. The Inogen BA-503 External Battery Charger lets you recharge a spare G5/Rove 6 battery off-device while your concentrator stays in use. Drop the battery into the desktop dock, check the status LEDs, and you’ll always have a fresh pack ready for errands, flights, or long days out.
Built to Inogen’s OEM specs, the charger uses a battery-optimized charge profile and integrated protections to support battery longevity. Compact, quiet, and 100–240 V compatible, it’s ideal for home, office, and travel.
Compatibility: For Inogen One G5 and Inogen Rove 6 batteries only (8-cell & BA-516 16-cell). Not for G3/G4.

Why Use an External Charger?

Zero downtime: use one battery while the other charges off-device
-
Faster turnarounds vs. charging through the concentrator (especially for BA-516)
-
Preserves device runtime: the concentrator isn’t tied to an outlet
-
OEM safety: correct voltage/current, over-temp and over-current protections
