G4 BATTERY OPTIONS:

*Based on oxygen flow setting of 2, a higher setting will use more battery power.

  • Small Battery - Lightweight 4-Cell Lithium Ion Battery (Up to 2 Hour Run-time)*
  • Large Battery - Double-Hour 8-Cell Lithium Ion Battery (Up to 4 Hour Run-Time)*

VIP FAA / AIRLINE NOTE:
The (FAA) Federal Aviation Administration requires oxygen users on board aircraft to carry 150% battery life to meet their oxygen needs while flying on all airlines. The flight hours must include not only time in the air but also layovers between legs of flights to your final destination airport.  
For examples:
  • 6 hr non-stop flight will require 9 hrs of battery life......... (6 hrs X 150% = 9 hrs)
  • 8 hr one-stop-flight with a 2 hr layover requires 15 hrs of battery life......... (8 hrs + 2 hrs = 10 hrs X 150% = 15 hrs)

    LITHIUM-ION BATTERY:
    Sometimes referred to as Li-ion battery or (LIB) is a member of a family of rechargeable battery types in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery. The electrolyte, which allows for ionic movement, and the two electrodes are the constituent components of a lithium-ion battery cell.

      Frequently Asked Questions

      Have questions? Learn more about how our products can support you.
      We guarantee our price to be the lowest of any Inogen One Authorized Dealer.  Be careful; there are only two of us in the USA! The others are buying somewhere other than Inogen One, the manufacturer.  In some cases, these are used machines that are represented as "New".  We always strive to offer good value and have special deals on our oxygen concentrators. But if you’re struggling to fit the oxygen concentrator, you need into your budget, or have found a competitive price elsewhere, speak to us. We always put our customers’ needs before profits. 
      Medicare will not purchase any Inogen One System, as Medicare classifies these as “Luxury Items.” Most insurance companies take the same stance as Medicare. However, a few insurance companies will reimburse all or part of your Inogen Oxygen system after purchasing and submitting the required claim forms. Inogen One Systems are the best on the market; owning the very best in portable oxygen is worth the investment.
      Here at Main Clinic Supply, we believe that everyone should have the chance to live their lives to the fullest! While many insurance companies and programs classify our state-of-the-art portable oxygen concentrators as "luxury items," we know they are anything but. As an oxygen user, you deserve access to oxygen equipment that will allow you to stay active and healthy.  Because of this, we have partnered with PayPal Credit and CareCredit to help make sure that every oxygen user has the chance to own the very best in portable oxygen and enjoy the freedom and mobility that it brings! Apply or check our options here.
      You may fax your prescription for oxygen to us at 1-800-819-7179 or email rx@mainclinicsupply.com. We are also happy to the obtain the prescription for you after you place your order here online.
      Free trials are something to be wary of. The majority of medical oxygen dealers share an interpretation of a “New Oxygen Concentrator Machine”, as a machine that has less than 100 hours of previous use. They don’t actually offer you a free trial, just a used machine you are made to think is new. At Main Clinic Supply, new means new, or never used before!
