Claims28
1-343. (canceled)
An oxygen concentrator system, comprising:
- at least two canisters;
- gas separation adsorbent disposed in at least two canisters, wherein the gas separation adsorbent separates at least some nitrogen from air in the canister to produce oxygen enriched gas;
- a compression system coupled to at least one canister, wherein the compression system compresses air during operation;
- an internal power supply coupled to the compression system, the internal power supply providing power to operate at least the compression system during use;
- wherein the internal power supply comprises an internal power supply input port;
- and
- an auxiliary power supply removably coupleable to the internal power supply input port;
- the auxiliary power supply comprising:
- one or more battery cells;
- a control circuit coupled to one or more of the battery cells;
- an auxiliary power supply input port coupled to the control circuit;
- and
- an auxiliary power supply output connector coupled to the control circuit;
- wherein the auxiliary power supply output connector is used to removably couple the auxiliary power supply to the internal power supply input port during use;
- wherein the control circuit directs flow of current through the auxiliary power supply during use.
