Before you order — confirm these
The Rhythm P2-E7 is a pulse dose concentrator only — it does not deliver continuous flow. Not appropriate for prescriptions specifying a continuous flow rate (LPM). Pulse dose during sleep requires physician guidance. Battery life specs are manufacturer best-case figures — in SW Florida summer heat, plan for 70-75% of published runtime. 866-218-0902
What Makes the Rhythm P2-E7 the High-Setting Value Leader
7 Settings in 4.37 lbs — Most Settings Per Pound Available
Seven pulse settings in a 4.37-pound concentrator. Most units that reach setting 7 weigh considerably more and cost considerably more. The P2-E7 gets there at a weight most patients can carry all day and a price point that makes it genuinely accessible. The only sub-5-pound unit on the market with 7 settings.
Room to Grow With Your Prescription
Seven settings means this concentrator has room to grow as a prescription changes, rather than requiring an upgrade as a condition advances. For patients on settings 5 or 6 today who may need more tomorrow, the P2-E7 provides that headroom without adding weight or cost now. The 1,400 ml/min maximum output is among the highest in the pulse dose category.
External Charger Included · DC Car Power · Worldwide AC
The external charger allows a spare battery to charge while the unit is running — no downtime waiting for a battery to top off. DC car adapter included standard. AC power is 100-240V worldwide, making the P2-E7 the right choice for snowbirds traveling internationally. Bright 2.8" LED display. 3-year device warranty.

Frequently Asked Questions
The P2-E7 is designed for patients on higher pulse settings — 5, 6, or 7 — who cannot afford to add weight. It is also a strong choice for patients currently on settings 3 or 4 whose condition may progress, since the extra headroom means the unit grows with them rather than requiring an upgrade. If your prescription calls for settings above what most 5-pound portables offer, the P2-E7 is often the right answer. 866-218-0902.
The Rhythm P2-E7 includes a separate external battery charger that charges a spare battery independently of the unit. While the concentrator runs on one battery, the spare charges in the external unit. When the active battery runs low, swap them — the concentrator keeps running without a gap. This is more practical than charging through the unit itself, which requires the concentrator to be off or plugged in during charging. 866-218-0902.
In SW Florida summer heat, plan for 70-75% of published battery specs. The P2-E7 rated at 6 hours at setting 1 will deliver approximately 4-5 hours at setting 2 on a hot day. The external charger makes managing a spare battery practical — charge one while running on the other to extend your time away from AC power. 866-218-0902.
Yes — FAA-approved for domestic commercial flight. The concentrator checks at the gate door; batteries must be carried in the cabin. The worldwide AC power (100-240V) makes it a practical choice for international travel as well. Call the airline at least 48 hours before your flight and bring enough battery for 150% of total travel time. 866-218-0902.
Yes. Our 10-Day No-Risk Trial lets you take the P2-E7 home and use it in your actual life for 10 days. If it is not the right fit, bring it back and we will exchange it. No restocking fee, no fine print. Walk-ins welcome at all five SW Florida locations. 866-218-0902.

Great toddler backpack!
Size: Small, Color: All Black
My daughter is in prek 3 and loves this backpack. Nice and small for her to carry. A full folder will fit with a little force, but if you’re looking for something to actually carry folders and books, maybe not the best.

“Tiny Backpack, Big Personality!”
This little backpack is doing big kid things — and my toddler knows it. The second we strapped it on, he marched around like he was off to close a business deal with juice boxes in both hands.
It’s the perfect size for tiny shoulders, and the chest buckle? GENIUS. No more slippy straps or bag-flinging tantrums. It stays put like a champ, even during epic playground sprints and spontaneous dance moves in the grocery store.
The material is sturdy, the zippers glide like butter, and the reflective strip makes my toddler look like he’s ready for a baby night shift. The color combo is sleek — black and grey with just the right touch of “cool kid on campus” energy.
Plenty of space for snacks, sippy cups, a favorite toy, and 14 mysterious pebbles he insisted on collecting “for science.”
If your 2-4-year-old wants to carry their own stuff and look proud doing it — this is the backpack for them. Highly recommend (and yes, I already ordered another one for backup... because toddlers). 🎒

Good! Recommend
Size: Small, Color: Pink Dino
My 2 year old loves this backpack. I love the snap in the front for additional support of the distribution of weight. It has a good size cup holders and the inside of the bag is very spacious.

A good buy especially for young kids
Our community is providing school supplies this year for an elementary school that we adopted. Backpacks are in big demand but, as you know if you’ve been shopping, pretty pricey. This backpack was a Prime-day find so I bought a couple of them but, even back to the regular price, it’s a good deal especially for very young kids. In person the backpack is cute and stylish with the vibrant range of colors you see in the product pictures. I bought the large backpack which, as you can see in the photo, is more than tall enough for a standard manila folder. The stitching seems sound and the straps work as you would expect; it also has two side pockets. If I had to pick a weak spot, I’d say it’s the zipper, especially the one on the front pouch. It’s not a problem at the moment but it’s nylon, not metal, and so I don’t expect it to last forever. But if it gets through one school year, I consider that good. I think it’s a pretty good buy if you’re on a budget.

Backpack Backpack
Size: Small, Color: Pink Dino
Cute, definitely a perfect size for my tall 3 yr old. (3’7”) I did have to let it air out though. Has a weird smell.
