INOGEN'S LIGHTEST PULSE-DOSE PORTABLE · GENUINE NEW INOGEN
2.9 lb of oxygen — the lightest Inogen makes
The Inogen Rove 4 is the lightest pulse dose portable oxygen concentrator Inogen builds — just 2.9 lb with the standard battery — with four settings and up to 840 mL/min of oxygen. Its three modular batteries let you trade a little weight for a lot more runtime, and it pairs with the Inogen Connect app over Bluetooth. It's the direct successor to the Inogen One G4.
American Oxygen sells genuine, new Inogen units with the full Inogen manufacturer warranty — FDA-cleared and FAA-approved.Why the Inogen Rove 4
2.9 lb — the lightest oxygen Inogen makes
With the standard battery the Rove 4 weighs just 2.9 lb — the lightest pulse dose portable in Inogen's line, built for people who found other concentrators too heavy to carry all day.
Three modular batteries
Choose Standard, Intermediate, or Extended depending on your day — Standard to stay ultralight, Extended for the longest time away from a wall outlet. All three are user-swappable.
FAA-approved & FDA-cleared
The Rove 4 is FAA-approved 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 — Standard, Intermediate & Extended
The same Rove 4 runs longer as you add battery capacity. Here's roughly how each pack performs across the four settings (hours per charge).
Approximate figures. Inogen officially publishes runtime for setting 1 only (Standard ~3 h · Intermediate ~4.3 h · Extended ~5.8 h); the settings 2–4 figures shown come from retail sources and vary with your breath rate, battery age, and temperature. Confirm exact figures with our team.
Runtime by setting — the three batteries
Higher settings use more oxygen and shorten battery time. Match your prescribed setting to the battery that fits your day.
| Pulse setting | Standard | Intermediate | Extended |
|---|---|---|---|
| Setting 1 | 3h 01m | 4h 29m | 5h 49m |
| Setting 2 | 2h 23m | 3h 34m | 4h 40m |
| Setting 3 | 1h 25m | 2h 08m | 2h 44m |
| Setting 4 | 0h 54m | 1h 24m | 1h 47m |
| Recharge — Standard battery | up to 3 hours (AC or DC) |
| Recharge — Intermediate battery | about 2h 32m |
| Recharge — Extended battery | about 3h 18m |
Inogen does not publish per-setting oxygen output for the Rove 4 beyond its 840 mL/min maximum, so this table shows runtime only. Times vary with your breath rate and conditions.
Rove 4 or Rove 6 — which fits you?
Both are genuine, light Inogen portables. The Rove 4 is the featherweight for lower settings; step up to the Rove 6 for two more settings, more output, and longer runtime.
| Inogen Rove 4 | Inogen Rove 6 | |
|---|---|---|
| Pulse settings | 1–4 | 1–6 |
| Max oxygen output | 840 mL/min | 1,260 mL/min |
| Weight (standard battery) | 2.9 lb | 4.8 lb |
