It delivers true continuous flow up to 3 LPM — the kind of steady delivery normally reserved for large home units, and what makes it suitable for overnight use and higher-demand needs — plus 10 pulse-dose settings for conserving battery and moving through the day. Both delivery modes live in one machine rated for 24\/7 use, so a single unit covers resting, sleeping, walking, and traveling.\u003c\/p\u003e\n  \u003cp\u003eIt's built to actually go places. At 17.2 pounds with the battery it's roughly half the weight of a traditional home unit, and it ships complete with a carry bag and a rugged transport cart with oversized wheels that roll easily over curbs and uneven ground. A universal 100–240V power supply keeps it running in most countries, AC and DC (car) cords are both included, and the battery engages automatically when unplugged — up to 6.6 hours on pulse setting 1, with spare batteries swapping in seconds. It's FAA-approved for commercial flights, warms up in 5 minutes, and reads out on a bright 2.8\" color LCD with simple controls.\u003c\/p\u003e\n\n  \u003ch2\u003eKey Features\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eDual delivery in one unit — continuous flow up to 3 LPM plus 10 pulse-dose settings.\u003c\/li\u003e\n    \u003cli\u003eTrue 3 LPM continuous flow supports overnight use and higher-demand needs.\u003c\/li\u003e\n    \u003cli\u003eRated for up to 24\/7 use — a single unit covers home, travel, and sleep.\u003c\/li\u003e\n    \u003cli\u003eLightweight at 17.2 lbs with the battery — about half a traditional home unit.\u003c\/li\u003e\n    \u003cli\u003eCarry bag and rugged transport cart with oversized wheels included.\u003c\/li\u003e\n    \u003cli\u003eUp to 6.6 hours of battery on pulse setting 1; spare batteries swap in seconds.\u003c\/li\u003e\n    \u003cli\u003eUniversal 100–240V power supply plus AC and DC (car) cords — ready for most countries.\u003c\/li\u003e\n    \u003cli\u003eFAA-approved for use on commercial flights.\u003c\/li\u003e\n    \u003cli\u003eBright 2.8\" color LCD with simple, easy-to-read controls.\u003c\/li\u003e\n    \u003cli\u003eFast 5-minute warm-up; 87%–96% oxygen concentration.\u003c\/li\u003e\n    \u003cli\u003eBacked by a 3-year device warranty (2-year sieve bed, 1-year battery).\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003cdiv class=\"enhdme-insight-box\"\u003e\n    \u003cp\u003eThe TOC3's real distinction is that it does something most portables can't: genuine continuous flow up to 3 LPM. Most travel-sized units are pulse-only, which is why they're often not an option for overnight use — the TOC3 gives you both, so one machine covers sleeping at home and a flight the next morning, instead of owning a stationary unit plus a portable. That's the \"hospital-to-home\" idea behind it. The tradeoff is honest: at 17.2 lbs it's heavier than a wearable pulse-only unit like the Rhythm P2, and continuous flow drains the battery faster (1.2 hours at 3 LPM versus 6.6 hours on pulse setting 1) — so plan on a spare battery if you'll run continuous flow away from an outlet. The included cart with oversized wheels does the carrying, and the universal power supply plus FAA approval make international travel realistic. If you only need pulse dose, a lighter unit is the better fit; if you need continuous flow and portability in one, this is the one that does it.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n  \u003cul class=\"enhdme-spec-list\"\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eType\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eTransportable oxygen concentrator (continuous + pulse)\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eBrand\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eRhythm Healthcare TOC3\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eContinuous Flow\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eUp to 3 LPM\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003ePulse Dose\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e10 settings\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eOxygen Concentration\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e87%–96%\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eRespiratory Rate\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e10–40 breaths\/min\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eWeight\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e17.2 lbs (with battery)\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eDimensions\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e11.1\" x 6.7\" x 15\"\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eWarm-Up Time\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e5 minutes\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eDisplay\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e2.8\" color LCD\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eDuty Cycle\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eUp to 24\/7 use\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eAC Input\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e100–240V AC, 50–60 Hz (universal)\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eBattery\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e14.4V DC rechargeable; ~4.5 hr charge time\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eBattery — Pulse\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e6.6h @1 · 4.9h @2 · 3.9h @3 · 3.6h @4 · 3.3h @5 · 3.0h @6 · 2.6h @7 · 2.3h @8 · 2.0h @9 · 1.8h @10\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eBattery — Continuous\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e3.1h @1.0 · 2.5h @1.5 · 1.9h @2.0 · 1.4h @2.5 · 1.2h @3.0 LPM\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eAir Travel\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eFAA-approved\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eWarranty\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003e3-yr device \/ 2-yr sieve bed \/ 1-yr battery\u003c\/span\u003e\n\u003c\/li\u003e\n    \u003cli\u003e\n\u003cspan class=\"enhdme-spec-label\"\u003eIncludes\u003c\/span\u003e\u003cspan class=\"enhdme-spec-value\"\u003eUnit, battery, AC + DC power supplies, cannulas, inlet filters, carry bag, cart, manual\u003c\/span\u003e\n\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003cdiv class=\"enhdme-faq-section\"\u003e\n    \u003cdiv class=\"enhdme-faq-item\"\u003e\n      \u003cp\u003e\u003cstrong\u003eCan I use it overnight?\u003c\/strong\u003e\u003c\/p\u003e\n      \u003cp\u003eYes — that's the point of the continuous flow.
