Inogen One G5 External Battery Charger BA-503

a very bit pricey, however its what I needed

Added more time to my Mothers day

oxygen necessity

Very lite and easy to charge batteries .

Charge batteries.

works great I can charge my spare battery while using my innogen

would buy again

Got this to charge spare batteries, it charged the battery better than the regular charging method.. Really like this charger .

This is an excellent battery charger for my Inogen, but it sure ought to be for the $300.00 price. It is amazing how much they rip us off on prices for the Inogen.

This was used on a pulse ox concentrator
