Technical Specifications

FAQ
What is the difference between the Inogen models?
The Rove 4 and Rove 6 are the current models. The Rove 4 is built for portability: 2.9 lbs, four pulse settings and up to 840 mL/min. The Rove 6 is built for performance: six settings, up to 1,260 mL/min and up to 12 hours 45 minutes on the extended battery, at 4.8 lbs.

The G4 and G5 are the previous generation. The G4 is the earlier version of the Rove 4, and the G5 is the earlier version of the Rove 6. They use the same batteries and accessories as their newer counterparts, which is why many long-time users still know them by those names.

So the choice comes down to one question: do you want the lightest unit you can carry, or more output and runtime?
Can I use this while I sleep?
The Rove 4 delivers pulse dose oxygen only, meaning it releases a dose when it senses you breathe in. Some people are prescribed continuous flow for sleep, and a pulse dose unit is not a substitute for that. Check your night-time prescription with your doctor before ordering, or call us and we will go through it with you.
What if I am not sure which concentrator is right for me?
Call us. Whether you need longer battery life, higher pulse settings or continuous flow, we will match a device to your prescription and to how you actually live. No pressure, and we will tell you honestly if this unit is not the right fit.
How many hours are on the unit?
Every certified pre-owned unit is different, so we do not publish a single figure. Call us and we will tell you the exact hours on the units we have in stock today, along with the battery condition, before you commit to anything.
Is Vital Care USA an authorized retailer?
Yes. We are an authorized Inogen dealer. Every unit carries authentic U.S. serial numbers and full warranty coverage. Unauthorized sellers can leave you with a grey-market device and no protection.
Do I need a prescription, and where do I send it?
Yes. U.S. law requires a valid prescription for most portable oxygen concentrators. You can email it to support@vitalcareusa.com, or your doctor can fax or email it directly. If you do not have a copy to hand, we will contact your doctor's office and retrieve it for you after the order is placed. Your order ships as soon as we have it.
Does insurance or Medicare cover this?
Medicare classifies portable oxygen concentrators as convenience items, so it does not approve them for purchase. Coverage is normally tied to in-network rental programs instead. Some private plans reimburse part of the cost after purchase with the right documentation, and we can tell you what to ask your insurer. Most customers buy privately for full ownership and the freedom to travel.
Can I pay with HSA or FSA funds?
Yes. Portable oxygen concentrators are generally HSA and FSA eligible when you have a prescription. Check the rules with your plan administrator, and keep your receipt and prescription for reimbursement.
What financing options are available?
You can apply instantly through Shop Pay Installments, PayPal Credit or Affirm. Approvals are fast and there is no paperwork.
Can you match a lower price?
Yes, on a genuine U.S. Inogen unit with warranty coverage. If you have seen a lower authorized price, tell us and we will review it and match or beat it wherever we can. Check first that what you are comparing is a genuine U.S. unit and not a grey-market import.
When will my order ship?
Most in-stock units ship within 1 to 2 business days once we have your prescription and have verified the order. Tracking is emailed automatically. Next-day delivery is available on select models and locations.
What if it does not work for me?
You have 30 days from delivery to return it. Call us and we will start the return and walk you through it. If the unit turns out not to suit your prescription we would rather sort that out than have you keep something that does not work for you.

Getting Started with the Rove™ 4

What's in the box?

Is the Rove 4 the right unit for you?

The Rove 4 delivers oxygen in pulse dose only, across four flow settings. It is the lightest unit Inogen makes, but it is not right for everyone.

  • Your setting falls between 1 and 4
  • You want the lightest unit you can carry, at 2.9 lbs
  • You want to fly, travel, or stay out all day

Worth a call first if

  • Your prescription calls for continuous flow
  • You need a setting above 4
  • You need oxygen while you sleep
  • You are not sure what your prescription says

Extend your coverage

5-Year Worry Free Coverage

$650
  • 5 total years from your purchase date
  • Columns and filters, when replacement is needed
  • Replacement unit if troubleshooting confirms a failure
  • Priority support and expedited service
See full terms

Choosing a portable oxygen concentrator is a long-term decision. The 5-Year Worry-Free Coverage option is designed to protect your investment beyond the standard manufacturer warranty and help reduce unexpected service or maintenance costs over time.

This plan extends your total coverage to 5 years from the original purchase date and provides support for service needs that may arise as your device is used regularly.

Why Coverage Matters

Inside every Inogen Rove device are sieve beds (also called columns) containing a mineral called zeolite, which is responsible for producing medical-grade oxygen. With normal use, these components are exposed to air, moisture, and environmental particles, which can affect performance over time.

Many patients also review or replace output and particle filters as part of ongoing device care to help maintain airflow and oxygen purity. Because usage and environments vary, service needs are addressed based on device performance rather than fixed schedules.

What’s Included

  • Coverage extended to 5 total years from the original purchase date

  • Support for service and maintenance not typically covered under the factory warranty

  • Coverage for columns and filters when replacement is required due to performance or operational concerns

  • Assistance with troubleshooting, alerts, and changes in operation

  • Access to software updates when applicable

  • Priority support and expedited service coordination

  • Replacement unit provided when required following troubleshooting confirmation

How It Works

  • Coverage applies to one active unit at a time

  • Service and replacements are provided as needed, based on device performance

  • No automatic shipments or unnecessary replacements

  • No subscriptions or recurring fees

  • If something doesn’t feel right, simply contact us and we’ll guide you through the next steps

Important Notes

  • Coverage begins on the original purchase date of the device

  • Replacement units inherit the remaining coverage term

  • Coverage applies to normal use and does not include misuse or intentional damage

This option is ideal for customers who want extended protection and predictable ownership costs without committing to rigid service schedules.

Coverage upgrades may be purchased at the time of order or added later. All coverage terms are tied to the original device purchase date.

Best value
$950

See full terms

For customers who want the highest level of long-term peace of mind, Lifetime Worry-Free Coverage provides protection for the usable life of your device.

This plan includes everything in the 5-Year Worry-Free option, with coverage continuing beyond traditional warranty timeframes — so you’re not left worrying about future repair or replacement costs as your needs evolve.

What’s Included

  • Coverage for the usable life of the device

  • Continued protection beyond standard and extended warranty periods

  • Coverage for columns and filters when service is needed to maintain proper operation

  • Replacement unit provided in the event of a covered device failure

  • Priority support for the life of your coverage

How It Works

  • Coverage applies to one active unit at a time

  • Service and replacements are provided when needed, based on verified performance issues

  • No annual contracts, subscriptions, or automatic shipments

  • Replacement eligibility is based on device condition and usage, not calendar years

  • If a replacement unit is issued, coverage continues based on the original purchase date and policy terms

Important Notes

  • Coverage begins on the original purchase date of the device

  • Replacement units inherit the applicable remaining coverage structure

  • Coverage applies to normal use and does not include cosmetic issues, misuse, or intentional damage

This option is best for customers who want long-term certainty and prefer not to worry about future service or replacement costs over the life of their device.

Coverage upgrades may be purchased at the time of order or added later. All coverage terms are tied to the original device purchase date.
