Inogen One G5 External Battery Charger BA-503

extra charger for Inogen portable supply..

ok

I thought this could be used without being plugged in, but it can’t. It’s still awesome. It charges batteries quickly. I can charge two batteries at a time. One attached to the Inogen G5 and the other one to this. I would recommend.

Does as says, charges batteries. Dislike, pricing seems high for a battery charger.

Mother’s oxygen machine

Extremely easy to use! Charges a battery without it needing to be on the Inogen oxygen concentrator. So I can charge two batteries at once! So convenient! Excellent value for the money!

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

This was used on a pulse ox concentrator

Easy to use.

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.
