What Makes a Good Travel POC?
Essential Travel Features
1. FAA Approval (Non-Negotiable)
- Must appear on FAA approved device list
- Label clearly visible on device
- Without this, airlines will deny boarding
2. Battery Life (Critical for Air Travel)
- Minimum: 150% of flight duration
- Domestic flights (3-5 hrs): Need 8-10 hours total battery
- International flights (10+ hrs): Need 15-20+ hours (challenging)
- Consider: Airlines limit spare batteries to 2 per passenger
3. Weight (Comfort Factor)
- Ultralight: Under 5 lbs (easy carry, less oxygen output)
- Mid-weight: 5-8 lbs (balanced)
- Heavy: 10+ lbs (more features, harder to carry)
4. Oxygen Flow Capability
- Pulse dose: Most common, conserves oxygen
- Continuous flow: Some users require this (fewer portable options)
- Flow range: Higher settings = more flexibility
5. Size and Portability
- Fits under airline seat

Buying Guide: Choosing Your Travel POC
Step 1: Determine Your Medical Needs
Consult Your Pulmonologist:
- Required oxygen flow rate
- Pulse dose vs. continuous flow
- Activity level oxygen needs
- Prescription for air travel
Step 2: Calculate Battery Needs
Formula: (Flight Time + 2 hrs delay) × 1.5 = Battery Hours Needed
Example Calculations:
3-hour domestic flight:
- (3 + 2) × 1.5 = 7.5 hours needed
- G5 with double battery: 13 hours ✅ Plenty
- G4 with double battery: 5 hours ❌ Insufficient
6-hour cross-country:
- (6 + 2) × 1.5 = 12 hours needed
- G5 with double battery: 13 hours ✅ Just enough
- Oxlife Independence: 8 hours ❌ Need additional solution
10-hour international:
- (10 + 3) × 1.5 = 19.5 hours needed
- Challenge: No single POC covers this with airline 2-battery limit
- Solution: Connecting flights with layover charging
Step 3: Consider Weight vs. Features
Priority Matrix:
Weight Priority (Ultralight):
- G4 (2.8 lbs) - Best
- G5 (4.7 lbs) - Good
- Accept: Shorter battery, lower flow
Battery Priority (Long Flights):
- G5 (13 hours) - Best
- Oxlife (8+ hours) - Good
- Accept: More weight
Budget Priority:
- AirSep Freestyle ($2,195) - Best value
- Oxlife Independence ($2,795) - Good performance
- Accept: Lesser-known brands
Step 4: New vs. Refurbished
New POCs:
- Full warranty (typically 3 years)
- Latest technology
- No usage history
- Higher cost
Refurbished POCs:
- Save 40-50%
- 6-12 month warranty typical
- Tested and certified
- Cosmetic imperfections possible
Recommendation: If budget allows, buy new for peace of mind. Refurbished okay from reputable medical equipment dealers with warranties.
Step 5: Verify FAA Approval
Before Purchasing:
- Check FAA approved list at faa.gov/hazmat/packsafe/
- Verify device has compliance label
- Confirm your specific model year is approved
- Save approval documentation for travel

Frequently Asked Questions
Q: Can I rent a POC instead of buying? A: Yes, rental companies offer POCs for travel ($50-150/day or $300-800/week). Good for occasional travelers. Not cost-effective for frequent use.
Q: Does insurance cover portable oxygen concentrators? A: Sometimes. Medicare Part B may cover POCs if medically necessary. Private insurance varies. Get pre-authorization.
Q: How long do POC batteries last? A: 3-5 years with proper care. Battery capacity degrades over time (20-30% reduction after 2-3 years).
Q: Can I use my home oxygen concentrator for travel? A: No. Home units aren't FAA-approved, too heavy, and require electrical outlet.
Q: What's the quietest POC for travel? A: Inogen G5 (38 dB) and G4 (40 dB) are quietest. Most are 40-50 dB (whisper to normal conversation level).
Q: Can POCs work at high altitude destinations? A: Yes, but may require higher flow settings. Consult doctor before traveling to altitude over 8,000 feet.
Q: What warranty should I expect? A: New POCs: 3-year warranty typical. Refurbished: 6-12 months. Extended warranties available ($200-500).
