THE LIGHTEST PORTABLE, AT OXYGO VALUE · AUTHORIZED OXYGO DEALER
2.9 lb of oxygen — the same 4-setting capability, OxyGo value
The OxyGo FIT+ is a featherweight pulse dose portable oxygen concentrator — just 2.9 lb with the single battery — with four settings and up to 840 mL/min of oxygen. It's the 2026 refresh of the OxyGo FIT line: two modular batteries let you trade a little weight for a lot more runtime, and American Oxygen includes the double 8-cell battery for up to 5h 49m of oxygen. It pairs with the free My OxyGo App over Bluetooth. Built by OxyGo (an Inogen company in Orlando, FL) on the same platform as the Inogen Rove 4, it's the OxyGo-branded twin of that portable — the same four settings and 840 mL/min — which we distribute as an authorized OxyGo dealer, at a lower price.
American Oxygen is an authorized OxyGo dealer. Every OxyGo FIT+ is a genuine, new unit — FDA-cleared and FAA-approved — backed by the OxyGo manufacturer warranty.Why the OxyGo FIT+
2.9 lb — the lightest way to carry oxygen, at OxyGo value
With the single battery the FIT+ weighs just 2.9 lb, and it delivers the same four settings and 840 mL/min you'll find in the pricier Inogen-brand Rove 4 — on the same platform — at genuine OxyGo value. Two modular batteries let you trade weight for runtime, and American Oxygen includes the double 8-cell (up to 5h 49m).
My OxyGo App — your concentrator on your phone
Pair over Bluetooth and the free My OxyGo App shows battery charge, sieve-column life, oxygen purity, hours of use, charge cycles, your current setting, and alerts — so you always know exactly where your unit stands.
FAA-approved & FDA-cleared
The FIT+ meets FAA acceptance criteria for commercial flights, so it flies in the cabin with you. It's a genuine, FDA-cleared prescription medical device — not a grey-market import.
Battery runtime — single 4-cell vs double 8-cell
The same FIT+ runs longer on the double 8-cell battery — which American Oxygen includes. Here's roughly how each pack performs across the four settings (hours per charge).
Settings 1 and 4 are confirmed by OxyGo's official figures; settings 2–3 come from a single retail source and are approximate. American Oxygen includes the double 8-cell battery (up to 5h 49m on setting 1). Runtime varies with your breath rate, battery age, and temperature — confirm exact figures with our team.
Runtime by setting — single vs double battery
Oxygen output rises with each setting, and battery time comes down. American Oxygen includes the double 8-cell for the longest runtime.
| Pulse setting | O₂ output | Single 4-cell | Double 8-cell |
|---|---|---|---|
| Setting 1 | 210 mL/min | 3h 01m | 5h 49m |
| Setting 2 | 420 mL/min | 2h 23m | 4h 40m |
| Setting 3 | 630 mL/min | 1h 25m | 2h 44m |
| Setting 4 | 840 mL/min | 0h 54m | 1h 47m |
| Recharge — single 4-cell battery | up to 2h 42m (AC or DC) |
| Recharge — double 8-cell battery | up to 3h 18m (AC or DC) |
The FIT+ holds a fixed minute-volume per setting: the bolus per breath adjusts to your breath rate to keep oxygen output steady — 210, 420, 630, and 840 mL/min at settings 1 through 4. Times vary with your breath rate and conditions.
OxyGo FIT+ vs Inogen Rove 4 — same machine, better value
Same platform, same capability. The FIT+ is the OxyGo-branded twin of the Inogen Rove 4 — identical four settings, 840 mL/min, and 2.9 lb featherweight body — but as an authorized OxyGo dealer we back it with the OxyGo warranty at a lower price.

Details
What is the OxyGo FIT+?
The OxyGo FIT+ is the lightest pulse dose portable oxygen concentrator in the OxyGo line — just 2.9 lb with the single battery — with four flow settings (1–4) and up to 840 mL/min of oxygen. Two modular batteries (single 4-cell and double 8-cell) let you trade weight for runtime, and American Oxygen includes the double 8-cell for up to 5h 49m. It pairs with the free My OxyGo App over Bluetooth. It's the 2026 refresh of the OxyGo FIT, built by OxyGo (an Inogen company in Orlando, FL) on the same platform as the Inogen Rove 4.
It is designed for users prescribed pulse dose oxygen therapy at lower-to-mid settings. It is not a continuous-flow concentrator — if you require continuous oxygen, confirm alternatives with your clinician.

Frequently asked questions
How long does the OxyGo FIT+ battery last?
On setting 1, about 3 hours on the single 4-cell battery and about 5h 49m on the double 8-cell — and American Oxygen includes the double. The setting-1 and setting-4 figures are confirmed by OxyGo, while settings 2–3 are approximate — confirm exact numbers with our team. Higher settings use more oxygen and shorten runtime, and many customers carry a charged spare for long days.
Why choose the FIT+ over the Inogen Rove 4?
The FIT+ is the OxyGo-branded twin of the Inogen Rove 4 — the same four settings, 840 mL/min, and 2.9 lb body, on the same platform. As an authorized OxyGo dealer we back it with the OxyGo warranty at a lower price, and you get the free My OxyGo App.
What is the My OxyGo App?
