Kingon P2-E Portable Oxygen Concentrator

The Kingon P2-E is a pulse dose portable oxygen concentrator that weighs 1.98kg with its battery fitted and comes with a padded carry case and an adjustable strap, so you can wear it over one shoulder like a handbag or across your body — either way, both hands stay free for a suitcase, a trolley or a handrail. It delivers up to 1,000 ml/min of oxygen across five flow settings at 90% concentration, runs at 37 dB(A) on setting 2, and is included in the ARTG. If you have been prescribed supplemental oxygen and want a device that fits your day rather than dictating it, this is the entry point to the Kingon P2 range.

Key Features

• 1.98kg including the battery — at 22.1 × 8.5 × 16 cm it sits at your hip like a small shoulder bag on the included strap, rather than being wheeled along behind you on a cart.
• Five pulse flow settings — up to 1,000 ml/min, approximately equivalent to 5 LPM, with headroom if your prescription is adjusted later.
• 90% oxygen concentration (−3% / +6%) at every setting — the concentration holds at all five settings, so turning the setting up does not dilute what you receive.
• 37 dB(A) at setting 2 — quieter than a normal conversation, so it is comfortable in a cinema, a waiting room or a bedroom.
• Two 6,800 mAh lithium-ion batteries included — swappable in seconds, recharging in roughly four hours from AC or the car.
• Smart breath detection — a sensor triggers a precise bolus at the start of each inhale and adjusts as your breathing rate changes. If no breath is detected it pulses automatically every three seconds.
• Triple filtration and a modular sieve bed — the sieve bed is designed to be swapped without returning the whole device for service.
• 24+ alarm types — including low battery, low oxygen concentration and no breath detected. Alarms can be silenced but stay visible on screen, which matters if a carer is nearby.

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. The only thing that changes is how much oxygen they deliver per pulse and how many settings you get. Your prescription decides which one you need — not your budget.

If your prescribed setting is 4 or 5 and unlikely to change, the P2-E is the sensible choice. If you have been told your requirement may increase, or you desaturate on exertion, look at the Kingon P2-E6 or the Kingon P2-E7 instead.

Battery Life at Every Setting

Figures below are per single battery, and two batteries come in the box — so a realistic day out is roughly double these numbers. Actual duration varies with ambient temperature, altitude and your breathing rate.

Both an AC supply for the wall and a DC supply for the car are included, so the P2-E can run and charge from the passenger seat on a long drive. If you already travel with CPAP equipment, our guide to travelling with CPAP covers the same power planning questions.

Flying With the Kingon P2-E

The P2-E holds FAA approval and is accepted for both domestic and international air travel, but Australian carriers each have their own paperwork and they want it in advance — not at the gate.

• Qantas requires an authorisation request form, submitted ahead of departure under their medical travel clearance guidelines.
• Virgin Australia requires a medical clearance form and lists approved personal medical equipment separately.
• Airlines generally expect you to carry enough battery for 150% of your total flight time, which is where the second battery earns its place.
• Spare lithium-ion batteries must travel in your cabin baggage, never in checked luggage.

We can supply the FAA declaration of conformity and the current Qantas and Virgin forms with your device — just ask when you order.

Important: Pulse Dose Oxygen and Sleep Apnea

Who Is This For?

The P2-E suits someone on a stable, lower-to-mid pulse dose prescription who is still active — walking, shopping, seeing family, getting on a plane — and who has found a cylinder or a stationary concentrator has quietly shrunk their world. It is also a sensible choice for anyone who has struggled with the weight of a 4–5kg concentrator, or who needs a device that a partner or carer can lift and manage easily.

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

What's in the Box

• 1 × Kingon P2-E portable oxygen concentrator
• 2 × lithium-ion batteries (6,800 mAh)

• 1 × portable DC power supply, for charging in the car
• 1 × padded carry case with adjustable shoulder strap
• 1 × nasal cannula
• 1 × set of 5 air filters
• 1 × user manual

A Kingon backpack and an external battery charger are available separately if you want to charge a spare while the device is in use. Standard inclusions can vary by bundle or current promotion — give us a call if you need a specific configuration confirmed before ordering.

Warranty and Australian Support

The P2-E 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-E monitors itself continuously and reports faults as numbered alert codes on its display. If you already own one and need to look a code up, our Kingon P2 alert codes guide lists all 23 — what each one means, whether the unit will shut itself down, and what to do about it.
