Purpose & User

This 90W AC adapter delivers 19V at 4.74A for the Inogen One G2 portable oxygen concentrator. It replaces a lost or damaged original charger and restores mains-powered operation for medical use at home or while travelling. The 10 ft total cord length gives flexibility in outlet placement.

Upgrade Context

The unit supersedes the factory-supplied power supply when that item fails or is misplaced. The jump is worth it when continuous 100-240VAC 50/60Hz input compatibility is required across different regions. Buyers who need a higher wattage rating or a different output voltage cannot use this model.

Sustained Operation

Built-in over current protection, over voltage protection, short circuit protection and overheat protection with a smart chip maintain stable output during extended sessions. FCC, CE and RoHS certifications confirm compliance with international safety standards for continuous medical-device duty. The 12 month warranty period reflects the manufacturer's confidence in long-term reliability.
