Everything about the Inogen Rove 4
Freedom you can hold in one hand
The Rove 4 weighs less than a laptop — 2.9 lbs with the standard battery, 3.4 lbs with the extended 8-cell battery included in this package. It hangs from a shoulder without pulling, rides in a small bag, and turns "carrying your oxygen" into an afterthought.
Intelligent Delivery Technology, tuned for efficiency
Like its bigger siblings, the Rove 4 senses every inhalation and delivers oxygen exactly on the breath. Four pulse-dose settings supply up to 840 ml/min — reliable support for daily activities, errands, and travel.
Battery power for real days
This package ships with the extended 8-cell battery: up to 5 hours 49 minutes on setting 1, recharging in about 6 hours from wall or vehicle power. Grab a spare and hot-swap for unlimited range.
Quiet enough for anywhere
At 39 decibels on setting 2 the Rove 4 is as quiet as a whispered conversation — welcome in libraries, meetings, restaurants, and beside a sleeping partner.
Travel-certified and warranty-backed
FAA approval means the Rove 4 boards any US commercial flight. Inogen covers the concentrator for 3 years and the battery and accessories for 1 year, and our specialists handle setup questions for as long as you own it.
