SeQual Eclipse 3 Portable Oxygen Concentrator Battery Power
One Power Cartridge is supplied with the Eclipse 3 Oxygen System, and provides up to 5.0 hours of battery operation (depending on flow rate and settings). Many patients choose to purchase additional Power Cartridges for extended excursion times between "power islands" - such as a home electric plug, etc. - whenever AC or DC power is available. Whenever connected to AC or DC power, the Power Cartridge recharges automatically.
