Inogen One G5 Single Battery

Designed exclusively for the G5 Portable Oxygen Concentrator, the Inogen One G5 Single Battery is the perfect travel accessory for your oxygen therapy. With a battery life of up to 6.5 hours, it offers greater freedom as you shop for groceries or go on road trips. This rechargeable lithium-ion battery also acts as a backup power source during power outages, giving you uninterrupted therapy.
