pM-KN03T Portable Oxygen Concentrator Analysis Report

Device Identification

The device shown in the visuals is a Portable Oxygen Concentrator designed for medical use, with a compact structure suitable for mobility. The device has an electronic and mechanical system that takes in ambient air, separates nitrogen, and provides enriched oxygen to the user. The product appears as a complete set, consisting of the main unit, an external battery, a carrying bag, and power adapters.

Brand and Model Information

Upon detailed examination of the device’s front control panel and screen area, a clear and distinct marking indicating model information was detected.

• Model: The designation pM-KN03T is located in the exact center of the control panel, directly below the screen, in capital letters. This code is the technical model identifier of the product.
• Brand Status: No logo or brand name belonging to common manufacturers such as “Kingon”, “Olive”, or “Phillips” was found on the outer casing of the device in the visuals. Since the product is often marketed as “White Label” (contract manufacturing) or the brand label might be on a different surface, only the “pM-KN03T” code, which is clearly visible in the image, has been taken as reference.

Areas of Use

This device is designed for patients with COPD (Chronic Obstructive Pulmonary Disease) or individuals requiring continuous oxygen support, to receive oxygen therapy outside the home or during travel. Thanks to its compact size and battery-powered structure, it aims to increase patients’ mobility freedom. The set in the visuals is suitable for use both with electricity at home and with a battery outdoors.

Quantity Information

The number of parts in the set shown in the visuals is as follows:

• 1 Oxygen Concentrator Main Unit
• 1 Removable External Battery (White, box-shaped)
• 1 Carrying and Protective Bag (Black, with strap)
• 1 AC/DC Power Adapter (Adapter body)
• 1 Power Connection Cable
• Total Number of Parts: 5 parts

General Condition

The product generally has a clean and well-maintained appearance. Although it is second-hand, it can be categorized as “lightly used” or “carefully used.” No yellowing is observed on its white plastic components; it retains its bright white color. There is no deep dirt or stain layer on the outer surface.

Physical Deformations and Cosmetic Examination

No significant damage that would affect the aesthetics or operation of the device was detected on its outer casing.

• Casing: No breaks, cracks, or prominent deep scratches are visible. Corners and joints appear intact.
• Air Channels: The ventilation grilles on the side panels appear clean; no dust accumulation or blockage is noticeable.
• Metal Tips: The oxygen outlet nozzle (metal cannula tip) is shiny and unrusted.

Mechanical and Electronic Components

• Control Panel: The control panel on the upper part of the device (On/Off button, plus/minus keys, mute button) appears sound. The markings on the buttons are not worn off.
• Door/Hinge: The grey-colored cover mechanism on the side, presumed to belong to the filter or battery compartment, is fully seated, with no gaps or deformation.
• Air Inlets/Outlets: The oxygen cannula outlet (barb connector) is sturdy and not bent.

Screen Analysis

A digital LCD screen is located on the upper part of the device.

• Screen Condition: Since the device is in the off position, no error codes or operating hours are visible on the screen. There are no deep scratches or cracks on the screen glass/plastic that would hinder operation.
• Symbols and Icons: On the left side of the screen, symbols representing “Pulse” (Pulse/Trigger mode), battery, and warning icons are visible. Additionally, in the upper right corner of the screen, there is a universal “No Smoking” warning symbol indicating that smoking is prohibited near this device.

Condition of Accessories

The condition of the accessories accompanying the product is consistent with the cleanliness of the device itself.

• Carrying Bag: The black fabric carrying bag is sturdy. No unraveling or tearing is observed in the zippers, strap attachments (metal rings), or seams. The transparent screen protection window is clean. The bag features perforated metal rings (eyelets) for air intake, which are unrusted.
• Power Unit: No crushing, breakage, or external insulation damage has been observed on the adapter and cables.

Battery Condition

In the visual, there is a white, rectangular battery pack standing separately from the main device.

• Physical Condition: No swelling, cracking, or signs of leakage are observed on the battery casing.
• Mechanism: The locking tabs and sliding mechanism appear sturdy. Based on visual analysis, no comment can be made regarding the battery’s charge retention performance; only its physical integrity has been confirmed.

Originality Assessment

The device’s molding craftsmanship, panel design, keypad quality, and the visual harmony of its accessories (adapter, battery, bag) indicate that the product is an original item from an industrial production line. It does not give the impression of being a copy or an assembled (custom-made) device.

Potential Fault Risk

As a result of the visual inspection, the device’s physical condition is very good. There are no significant negative issues that could be mentioned under the “Potential Fault Risk” heading, such as crushed cables, impact-related cracks in the casing, oxidation, or excessive wear. The physical data indicate that the device has been used cleanly and carefully, and mechanical risks are low.
