Why this concentrator

Up to 7 hours on a single battery

Setting 1 runs up to 7 hours from one internal battery — the longest single-battery runtime in the family. Carry a charged spare for full travel days.

FAA-approved & FDA-cleared

The E7 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.

In short

The Open Box Rhythm P2-E7 is a brand-new, never-used Rhythm P2-E7 — the box was opened only for display — offered below sealed-stock price. It's a genuine, FDA-cleared, FAA-approved portable oxygen concentrator with 7 pulse settings and up to 1,400 mL/min — the most oxygen the P2 family carries — in a 4.37 lb body, sold by American Oxygen (an authorized Rhythm dealer) with the full Rhythm factory warranty and free U.S. shipping over $99.

Frequently asked questions

What does “Open Box” mean for the Rhythm P2-E7?

An Open Box Rhythm P2-E7 is a brand-new, unused unit — the sealed box was opened only for photos or display and then set aside. It has never been used on a patient, it's genuine and current-generation, and it carries the full Rhythm factory warranty. You simply pay less than for sealed stock.

How long does the P2-E7 battery last?

Up to 7 hours on setting 1 from the single battery — the longest in the P2 line. Higher settings use more oxygen and shorten runtime, down to about 1.7 hours at setting 7. Many customers carry a charged spare for long days.

Is the P2-E7 approved for airline travel?

Yes. The P2-E7 is FAA-approved for use on commercial flights and travels in the cabin with you. Airlines typically ask for advance notice and enough charged batteries for about 150% of your flight time.

Do I need a prescription to buy it?

Yes. The P2-E7 is an FDA-cleared prescription medical device. American Oxygen can help you understand what's needed — just ask when you call.

How is the E7 different from the E6 or the TOC3?

The E6 has six settings and 1,200 mL/min; the E7 goes to seven settings and 1,400 mL/min — the most any P2 portable delivers. The TOC3 is a heavier transportable that adds continuous flow. If you need continuous oxygen, look at the TOC3.

Is this a new unit with warranty?

Yes. American Oxygen is an authorized Rhythm dealer, and every Open Box Rhythm P2-E7 is genuine and unused, backed by the full Rhythm manufacturer warranty — 3 years device, 1 year sieve columns, 1 year battery — plus our local support.

Not sure Open Box is right for you? We'll walk you through it.

Great Machine!
Excellent unit. Despite being from China, it’s still the most powerful machine I’ve ever used and cheapest than others brands. My trips to the doctor are no longer consumed by my nerves and anxiety. Now I know I’m on oxygen. 7 flow options make my life easier at 69 years old.
