Pros and cons
PROS
- 13,123 ft published operating altitude ties the Eclipse 5 — the highest-rated active or discontinued portable
- 1–9 pulse settings plus 0.5–3 LPM continuous flow delivery in one unit
- 6.34 kg weight is 2 kg lighter than the Eclipse 5's 8.3 kg — meaningful for daily handling
- 40 dB published sound level matches the Eclipse 5 at bedside
CONS
- Stock: Discontinued per manufacturer brochure and e-commerce product listings
- No Oxygen Purity Indicator (OPI) — gap for unattended or long-trip use
- 2.7 hours battery at pulse setting 2 is significantly shorter than the Eclipse 5's 5.4 hours
The SeQual Equinox is the Eclipse 5’s lighter sibling in the SeQual/Caire line — a 6.34 kg dual-mode portable (0.5–3 LPM continuous plus 1–9 pulse settings) indicative retail ₹3,36,000 (varies by region/dealer), now listed as Discontinued per manufacturer brochure and e-commerce product listings. It carries the same 13,123 ft operating altitude and 40 dB sound as the Eclipse 5 at a lower weight, but pays for that with a significantly shorter battery life and — critically — the absence of an Oxygen Purity Indicator. FDA, FAA and CE certifications are all confirmed in the published additional details, and it is an Indian Voltage Model.
What the specs actually mean
Published purity is 90–95% — standard PSA pulse/continuous envelope. The Equinox does not have an OPI per the technical details — the field is empty. It does have a full set of alarms: loss of power, system malfunction, and no flow all flagged “Yes” in additional details, which is a more complete alarm package than many pulse-only portables but does not substitute for OPI.
The flow architecture mirrors the Eclipse 5. 0.5–3 LPM continuous and 1–9 pulse settings are delivered from the same unit, with a 16 mL mL dose at setting 1. For patients whose prescription calls for continuous flow above 2 LPM on the move, or pulse settings 6–9, the Equinox delivers the clinical capability — but only at a shorter battery runtime than the Eclipse 5.
The 6.34 kg weight is the middle ground. Eclipse 5: 8.3 kg; Equinox: 6.34 kg; premium pulse portables: 2.3–2.6 kg. 6.34 kg is still cart-territory (not shoulder-strap wearable for long) but 2 kg lighter than the Eclipse 5 — meaningful for daily handling in and out of vehicles or up hotel stairs.
Battery backup at pulse setting 2 is published at 2.7 hours from the internal battery, extending to 5.9 hours with the external battery pack. This is significantly shorter than the Eclipse 5 (5.4 hours base; external duration varies by battery variant). For dual-mode portables, battery endurance is a critical planning variable — the Equinox base battery rates closer to the SimplyGo Mini’s 4.5 hours than the Eclipse 5’s 5.4 hours. Recharge time is 4 hours.
40 dB sound and 13,123 ft altitude
The 40 dB published sound level matches the Eclipse 5. It is at the quiet end of the portable segment. 13,123 ft operating altitude also matches the Eclipse 5 — covering Leh, Spiti, Rohtang Pass in season, Leh-Manali road approaches, and the entire Himalayan pilgrimage circuit below the highest mountain passes.
Who should buy it
Realistically very few 2026 buyers, given the Discontinued status. The narrow fit is a residual-stock buyer who specifically needs dual-mode delivery plus 13,123 ft altitude and cannot handle the 8.3 kg weight of the Eclipse 5. The Equinox’s 2 kg weight saving is genuine — for patients or caregivers who struggle with the Eclipse 5’s weight at rail platforms or hotel stairs, the Equinox is a real alternative.
For households that already own a compatible Caire service relationship and have access to residual Equinox inventory with a written parts-and-service assurance, the altitude plus dual-mode combination in a 6.34 kg package is meaningful. That said, the missing OPI is a real clinical gap — sieve-bed contamination in humid Indian environments will not be flagged automatically.
The narrow defensible profile: a pilgrimage or Leh-class travel use case where the patient needs continuous flow above 2 LPM on battery, the caregiver cannot manage the 8.3 kg Eclipse 5 over extended rail and road journeys, and a dealer has offered residual stock at a discount to the ₹3,36,000 indicative retail with written parts-and-service commitments. That combination exists but is uncommon. For that specific buyer, the Equinox’s 6.34 kg weight makes the difference between a feasible trip and one that requires additional caregiver assistance.
Who shouldn’t
Anyone buying new in 2026 for this class of capability should buy the Eclipse 5 instead. The Eclipse 5 is In Stock, the Equinox is Discontinued — that alone resolves the decision for most buyers. The Eclipse 5’s longer battery life (5.4 hours vs 2.7 at pulse 2) and OPI presence outweigh the Equinox’s 2 kg weight advantage for most use cases.
Anyone whose prescription does not need dual-mode delivery should not buy the Equinox. A pulse-only portable (G5, SimplyGo Mini, Freestyle Comfort 5) covers mild-to-moderate pulse prescriptions at lighter weight, longer battery life, and lower price. Paying ₹3,36,000 for a dual-mode Equinox when a ₹2,14,999 G5 covers the clinical need is a poor use of the patient’s budget.
Anyone for whom OPI is important — which is most home-oxygen patients for long-duration use — should not buy the Equinox. The absence of OPI on a dual-mode portable is a more serious gap than on a pulse-only portable, because dual-mode units are often used for longer continuous-flow trips where purity monitoring matters more. For a patient running 1–2 LPM continuous flow on battery during travel, an undetected sieve-bed contamination event means the patient is receiving potentially sub-therapeutic oxygen for the duration of the trip.
Anyone who assumes residual stock automatically means discount pricing should verify: ₹3,36,000 is the published indicative retail, and residual-stock pricing can actually be higher if inventory is scarce. Compare against the ₹2,87,040 for the Eclipse 5 before committing.
Anyone in a tier-2 Indian city without Caire-authorised service coverage should not buy a discontinued Caire portable at any price. The service reality for discontinued Caire dual-mode units in tier-2 cities is effectively “parcel the unit back to Delhi or Mumbai for service” — turnaround on that workflow is 4–8 weeks, which is unacceptable for a portable that the patient depends on daily.
How it compares to real alternatives
Equinox vs SeQual Eclipse 5
Direct comparison in the SeQual family. Eclipse 5: 8.3 kg, 1–9 pulse + 0.5–3 LPM continuous, 5.4 hours at pulse 2, 40 dB, has OPI, 13,123 ft altitude, ₹2,87,040, In Stock. Equinox: 6.34 kg, 1–9 pulse + 0.5–3 LPM continuous, 2.7 hours at pulse 2, 40 dB, no OPI, 13,123 ft altitude, ₹3,36,000, Discontinued. The Equinox is 2 kg lighter but has half the battery life, no OPI, is Discontinued, and is more expensive at the listed retail. The Eclipse 5 wins on every axis except weight. Pick the Equinox only if weight is genuinely the single deciding factor and you have residual-stock access with written parts-and-service assurances.
Equinox vs Philips SimplyGo
Comparable dual-mode capability. SimplyGo: 4.5 kg, 0.5–2 LPM continuous + 1–6 pulse, 3 hours at pulse 2, 43 dB, has OPI, 10,000 ft altitude, ₹2,10,700, In Stock. Equinox: 6.34 kg, 0.5–3 LPM + 1–9 pulse, 2.7 hours at pulse 2, 40 dB, no OPI, 13,123 ft altitude, ₹3,36,000, Discontinued. Pick the SimplyGo if 2 LPM continuous and 10,000 ft altitude are sufficient — active stock, lighter, cheaper, has OPI, Philips service network. Pick the Equinox only if altitude above 10,000 ft is load-bearing and continuous above 2 LPM on battery is clinically required — and even then, the Eclipse 5 is the stronger pick.
Equinox vs Inogen One G5
Very different use cases. G5: 2.6 kg, pulse only, no continuous flow, 6.5 hours at pulse 2, 38 dB, has OPI, 10,000 ft altitude, ₹2,14,999, In Stock. Equinox: 6.34 kg, dual mode, 2.7 hours at pulse 2, 40 dB, no OPI, 13,123 ft altitude, ₹3,36,000, Discontinued. Pick the G5 if pulse-only is sufficient and the altitude envelope stays below 10,000 ft. Pick the Equinox only if dual-mode delivery plus high altitude is clinically necessary — but the Eclipse 5 is almost always the better choice for that combination.
Equinox vs Caire Freestyle Comfort 5
Both in the Caire family. Freestyle Comfort 5: 2.3 kg, pulse-only 1–5, 4 hours base / 16 hours extended at pulse 2, 39.9 dB, has OPI, 10,000 ft altitude, ₹2,48,640, Out of stock. Equinox: 6.34 kg, dual mode, 2.7 hours base / 5.9 hours extended at pulse 2, 40 dB, no OPI, 13,123 ft altitude, ₹3,36,000, Discontinued. Pick the Comfort 5 if pulse delivery is sufficient and weight is load-bearing — 4 kg lighter. Pick the Equinox only if continuous-flow delivery above 2 LPM and altitude above 10,000 ft are both clinically required and residual stock is genuinely available at a discount.
Indian-market considerations
The Equinox is Indian Voltage Model per published additional details — 220V/50Hz compatible without a step-down transformer. A 1 kVA inline stabiliser for home AC charging in voltage-variable tier-2 cities is optional.
CDSCO approval status is not stated in the published key features or additional details for this SKU in the data we reviewed (CDSCO Medical Device Registry). Discontinued SKUs frequently have lapsed Indian registration; verify with your dealer.
Caire/SeQual India service network is thinner than Philips or Inogen, and service for discontinued SKUs is structurally worse because spares are sourced from residual manufacturer inventory. For the Equinox specifically, battery replacement lead times in India have historically been 4–6 weeks, and sieve cartridge availability may be limited. Before purchasing residual stock, verify in writing: (1) spare battery price and lead time, (2) sieve cartridge availability, (3) out-of-warranty service commitment from the dealer.
Online-vs-hospital channel gap is wide on discontinued portables — hospital channels do not stock them. The Equinox is an online-dealer-only purchase at this point.
For international travel use, the FAA approval is published in the additional details. For a discontinued SKU, however, the paperwork flow at Indian airports may involve more scrutiny than for a current-model portable — allow additional time at check-in and carry the FAA approval letter and the manufacturer’s current serial-compatibility documentation. Some Indian dealers supply the FAA paperwork as part of the sale package; verify before your first flight with the unit.
Verdict
The SeQual Equinox is a capable mid-weight dual-mode portable that has been superseded in the Indian market by its own sibling, the Eclipse 5 — active stock, longer battery life, OPI present, and lower retail price. The 2 kg weight advantage is genuine but not enough to overcome the cumulative disadvantages of discontinuation, missing OPI, and shorter battery.
Score it 6.6 out of 10. Points off for the Discontinued status, the missing OPI, the 2.7-hour base battery at pulse 2, and the higher retail price than the better-specced Eclipse 5. Points on for the 13,123 ft altitude, the dual-mode delivery, and the 40 dB sound. For a specific buyer who absolutely needs dual-mode capability at high altitude in a 6.34 kg package and has written parts-and-service assurances for a discontinued SKU, this is defensible. For almost every other buyer with this capability requirement, the Eclipse 5 is the right choice.
