P2 Product Review

Rhythm Healthcare is a relatively new manufacturer to join the portable oxygen concentrator market, but the introduction of the P2 Portable Oxygen Concentrator came at just the right time. When other manufacturers were facing long delays due to supply chain issues, Rhythm Healthcare provided a portable concentrator that filled the gap and is proving to be a welcome addition to the market.

What you get with the P2

The Rhythm P2 comes standard with the P2 concentrator in a snug-fitting carry bag with shoulder strap, AC and DC adapters for home and car, and one (1) rechargeable battery. Optional accessories include a desktop battery charger and backpack.

The P2 measures 8.7″ wide x 6.3″ high x 3.3″ deep and weighs just 4.37 pounds. It offers 5 flow settings and provides up to 5 hours of battery time on setting 1 (4 hours on setting 2).


Comparing the P2 to other POC Models

The P2 is larger and more powerful than the Inogen One G4, smaller and just as powerful as the SimplyGo Mini and CAIRE Comfort, and smaller yet less powerful than the Inogen One G5, which provides 6 flow settings.

P2 –  What I like about it

While remaining very competitive in size and functionality, the P2 is notably less expensive than other models. A savings of several hundred dollars can make a difference for many in whether they can enjoy the benefits of a portable oxygen concentrator or not.

There is also a nifty feature that I have not seen with other POC models. The shoulder strap of the carry bag has an extra velcro piece that can be used to corral the nasal cannula and keep it close to the strap, which is helpful when wearing the unit over your shoulder.

P2 – What I Wish Were Better

Unlike other portable concentrators, such as the Inogen One G5, SimplyGo Mini, and CAIRE Comfort, which place the battery at the foot of the machine and can easily be accessed via the zippered opening, the P2 places the battery at the top of one end of the unit. This actually makes it easier to change the battery once the unit is out of the carry bag; however, since most people like to keep their machine in the carry bag, it has to be removed from the bag in order to change the battery. The carry bag is understandably a snug fit around the unit so it may be a hindrance for long travel where multiple battery changes are necessary. Fortunately, the battery is long-lasting and provides sufficient time for most excursions, including shopping or doctor’s appointments.

All-in-all, the P2 provides oxygen users with a quality machine at a bit more economical price and is worth your consideration when choosing an oxygen concentrator.
