Inogen One G5 External Battery Charger BA-503

My sister-in-law needed extra battery packs for going outside and for when the power was out in her building. So happy to have this extra insurance.

Charges G5 battery without having to keep concentrator plugged in!

Works with my G5 but have had times when the red lite flashes and it takes several times to get it to work.

Added more time to my Mothers day

going in vacation and had to order this for the multiple inogen batteries we have. Came on time and works perfectly and at almost half price of the mfg website. Just received batteries from same company. Trust this company, they delivered !!

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!

extra charger for Inogen portable supply..

The g5 charger was the wrong size for my batteries. It should have been a g4. I returned it

would buy again

Purchased to keep my batteries ready to go. Expensive but worth it because I always have a battery to go and since Im using oxygen 24-7, this is a valuable asset!!
