O2 Concepts Oxlife Liberty2 Battery Charger Kit

External desktop charger for Liberty2 battery packs — fast, safe, and travel-ready

 

Keep your Liberty2 running all day by charging batteries outside the concentrator. The Oxlife Liberty2 Battery Charger Kit is a compact, external charging base designed specifically for Liberty2 lithium-ion packs. While one battery powers your device, the other charges to full—so you can swap and go with virtually no downtime.

Engineered with smart charge control, this charger optimizes charge rate and protects battery health over the long term. It accepts universal AC input (100–240 V) for use at home or abroad (USA cord included; plug adapter may be required internationally).

Note: This charger does not power the concentrator. It charges batteries only.
