Frequently Asked Questions
The G4 is the lightest unit Inogen makes β 2.8 lbs β but covers only settings 1-3. The G5 covers settings 1-6, weighs 4.7 lbs, and delivers up to 13 hours on the double battery. If your prescription is settings 1-3 and weight is the priority, the G4 is the answer. If you need settings 4-6 or all-day battery life away from power, the G5 is the right unit. 866-218-0902.
The G4 is clinically validated for 24/7 waking use. Whether it is appropriate for nighttime use depends on your specific prescription and breathing pattern during sleep. Your physician's guidance on nighttime use is essential before using any pulse dose unit overnight. 866-218-0902.
The G4 single battery delivers up to 2.6 hours; the double up to 5 hours. In SW Florida summer heat, plan for 70-75% of those figures. For patients who are always near AC power β medical appointments, visiting family, short errands β this is manageable. For longer outings, carry a spare double battery and know where you can plug in. If your day regularly takes you away from power for 6+ hours, the G5 or Rove 6 is a better fit. 866-218-0902.
Yes β FAA-approved for domestic commercial flight. The concentrator checks at the gate door; batteries must be carried in the cabin. Given the short battery life, bring multiple batteries and calculate 150% of total travel time. Call the airline at least 48 hours before your flight. 866-218-0902.
Yes. Our 10-Day No-Risk Trial lets you take the G4 home and use it in your actual life for 10 days. If it is not the right fit, bring it back and we will exchange it. No restocking fee, no fine print. Walk-ins welcome at all five SW Florida locations. 866-218-0902.
