What happens if the power fails while I’m using the DeVilbiss iGo Portable Oxygen Concentrator?

If the iGo is powered by an external source and that source fails, the iGo will instantly turn to the internal battery pack (if the battery is installed). iGo Oxygen Concentrator can immediately turn back to electrical power if the external power is returned before the battery is completely depleted. If external power is not restored, the iGo can display battery condition information and emit an audible beep. When the battery is dead, the external power light on the control panel will flash. The iGo will sound a noticeable beep and the external power light on the control panel will flash automatically if there is no internal battery pack attached.
