Head-to-head
GCE Zen-O vs. Oxlife Independence
Both offer pulse and continuous flow. The Zen-O is lighter; the Independence reaches 3 LPM continuous.
Quick verdict
Choose the GCE Zen-O if…- You want the lighter unit — 10.25 lb vs. 16.7 lb
- Your continuous prescription is 2 LPM or less
- Longer pulse-mode runtime matters (4 hr vs. 2 hr 53 min per battery at setting 2)
Choose the Oxlife Independence if…- You need continuous flow up to 3 LPM
- You want more continuous runtime at 2 LPM — 1 hr 15 min per battery vs. 45 min
- A little extra weight is worth the higher flow
