Kingon P2-E7 Portable Oxygen Concentrator

The Kingon P2-E7 is the top of Kingon's ultra-light P2-E range, and it is usually sold on its output — 1,400 ml/min across seven flow settings, approximately equivalent to 7 LPM. That is not the most useful thing about it. On its lowest setting the P2-E7 runs for 7 hours on a single battery, against 5 hours for the P2-E. With both batteries in the bag, that is a genuine full day out. It weighs the same 1.98kg as the P2-E and P2-E6.

Seven Hours on One Battery

Battery life is what most people actually run out of. A concentrator that lasts four hours quietly shortens your day — you plan around the charger, you cut the trip short, you leave early. The P2-E7 removes that calculation for most everyday use.

Both an AC supply for the wall and a DC supply for the car are included, so the P2-E7 can run and charge from the passenger seat. Our guide to travelling with CPAP and oxygen equipment covers the same power planning questions, and airlines generally want enough battery for 150% of your flight time — a requirement this model meets more comfortably than most.

Worth Considering Even on a Lower Prescription

Here is something no one selling this device seems to mention. The P2-E7 is marketed as the high-output model, which makes it sound relevant only to people on demanding prescriptions. But the battery advantage applies whatever setting you use. If you are on a modest requirement and spend long days away from a power point — volunteering, minding grandchildren, fishing, travelling — the extra runtime may matter more to you than the extra output ever will.

That does not make it the right choice for everyone. It is the most expensive model in the range, and if your requirement is stable and your days are short, the Kingon P2-E will serve you perfectly well for considerably less. But do not rule the E7 out simply because you are not on a high setting — that is the wrong reason to skip it.

Key Features

• 1,400 ml/min maximum pulse output — approximately equivalent to 7 LPM, the highest of the three ultra-light P2-E models, across seven flow settings.
• Up to 7 hours per battery on setting 1 — the longest runtime at the lowest setting of any Kingon P2 model, including the larger P2-TOC.
• 90% oxygen concentration (−3% / +6%) at all seven settings — concentration holds right to the top of the range.
• 1.98kg including the battery — identical to the entry model, worn at your hip on the included shoulder strap.
• 37 dB(A) at setting 2 — quieter than a normal conversation.
• Two 6,800 mAh lithium-ion batteries included — swappable in seconds, recharging in roughly four hours from AC or the car.
• Smart breath detection — delivers a precise bolus at the start of each inhale. If no breath is detected it pulses automatically every three seconds.
• 24+ alarm types — including low battery, low oxygen concentration and no breath detected.

Kingon P2-E, P2-E6 and P2-E7 Compared

All three share the same 22.1 × 8.5 × 16 cm dimensions, the same 1.98kg weight and the same 37 dB(A) noise level at setting 2. What changes is output, the number of settings, and — the part usually left out — how long they last.

Two things worth reading off that table. The P2-E7 lasts 40% longer than the P2-E at its lowest setting. And all three give you roughly 1 hour 42 minutes on their top setting — buying more output does not buy a longer day at maximum, it buys a higher ceiling that costs runtime when you reach for it. If your needs sit mid-range, the Kingon P2-E6 may be the better fit.

Important: Pulse Dose Oxygen and Sleep Apnea

Who Is This For?

Two groups, and they are not the same people. The first is anyone on a higher pulse dose prescription who has been told a five- or six-setting device will not give them enough headroom — for them the E7 is simply the model that fits. The second is anyone, on any prescription, whose limiting factor is time away from a power point rather than oxygen output. Long days, long drives, long flights, or simply not wanting to think about the charger.

It is not the right device if you have been prescribed continuous flow, if you need oxygen while you sleep, or if you cannot tolerate a nasal cannula. Speak to us before ordering in any of those cases — a continuous flow model will be the correct fit.

What's in the Box

• 1 × Kingon P2-E7 portable oxygen concentrator
• 2 × lithium-ion batteries (6,800 mAh)
• 1 × standard AC power supply, for charging at home
• 1 × portable DC power supply, for charging in the car
• 1 × carry case with shoulder strap
• 1 × nasal cannula
• 1 × set of 5 air filters

A Kingon backpack and an external battery charger are available separately — the external charger is worth considering on this model in particular, since it lets you top up a spare while the device is running. Standard inclusions can vary by bundle or promotion; call us if you need a configuration confirmed before ordering.

Using Oxygen Safely at Home

Oxygen itself does not burn, but it makes everything around it burn faster and hotter — clothing, bedding, hair, even skin that oxygen has soaked into. The precautions are about the room rather than the machine: three metres between the concentrator and any flame, no candles, smoking or vapes, water-based products only on your face and hands, and nothing covering the intake or vents.

One thing worth doing before your machine even arrives: ring your electricity retailer and register as a life support customer. It is free, it protects your supply from disconnection, it entitles you to written notice of any planned outage, and rebates are available in New South Wales, Victoria and the ACT.

Our full guide to using oxygen safely at home covers fire precautions, electrical rules, blackout planning and what to tell emergency services. A printed copy comes in the box with every concentrator we send.

Warranty and Australian Support

The P2-E7 carries a three-year standard warranty, extendable to five years free of charge when you register the device with Kingon within 14 days of purchase. The battery and sieve bed are covered for 12 months. Kingon maintains a national Australian support network, so servicing does not mean shipping your device overseas.

The P2-E7 reports faults as numbered alert codes on its display. Our Kingon P2-E alert codes guide lists all 23 numbered display codes — identical across the P2-E, P2-E6 and P2-E7.
