Model pM-KN03T Portable Oxygen Concentrator Analysis Report

Device Identification

The main product shown in the images is a portable medical respiratory support device placed inside a special black carrying bag. Considering the device’s design, its control panel, digital screen, keypad structure, and air outlet nozzle, it has been determined that this product is a Portable Oxygen Concentrator. The presence of vital accessories such as a battery, charging unit, and power adapters alongside the device confirms that it is a complete set for mobile use.

Brand and Model

Upon examining the labeling on the front of the product, below the control panel and screen, the device’s model is clearly visible as pM-KN03T. This model number indicates that the product belongs to a specific technical series within the portable oxygen concentrator class. Although a large brand logo belonging to the device (e.g., universal main brands like Philips, Inogen, etc.) is not clearly discernible in the images, the model number definitively identifies the device.

Originality

Upon examining the layout of the buttons on the device’s control panel, the mounting quality of the screen, the stitching of the bag, and the accessories perfectly compatible with the device (battery slot and adapters), the product appears to meet original manufacturing standards. The clear printing of the labels (the presence of CE markings, the adapter label stating voltage values) supports the conclusion that the product is an original medical device.

Areas of Use

This device is designed to meet the oxygen needs of patients suffering from respiratory failure, COPD, or similar lung conditions. Its “portable” nature allows patients to receive oxygen support outside the home, during travel, or inside a vehicle. Its bagged structure and battery-powered system indicate that the device is suitable for patients on the go (situations requiring mobility).

Quantity Information

The set content shown in the images consists of a total of 5 main components:

• 1 Portable Oxygen Concentrator (inside a black carrying bag)
• 1 AC/DC Power Adapter (black brick type) and its power cord
• 1 Car Cigarette Lighter Charging Adapter
• 1 External Battery (White)
• 1 Desktop External Battery Charging Cradle (White cradle)

General Condition

The product is in clean and used general condition. No significant wear, tear, or detachment is observed on the device’s black protective bag. The exterior surfaces of the accessories (adapters and battery) appear clean. The product gives the impression of having been maintained or used carefully.

Physical Deformation

During the inspection, no deep scratches, dents, cracks, or deformation that would compromise the body integrity were detected on the visible parts of the device. The fabric texture of the black bag remains intact. No yellowing or discoloration is noticeable on the white battery and charging unit; the plastic components retain their whiteness.

Mechanical Components

The air outlet port (metal nozzle) on the front of the device is intact and in place; no deformation is observed. The bag’s zippers and the carrying strap’s attachment clips appear visually sound. No broken parts were observed on the battery’s charging slot tabs and connection points.

Electronic Components

The keypad on the device’s main unit (On/Off, +, -, Mute/Alarm) is not faded and is legible. No physical crack is observed on the digital screen panel. The contact points (pins) of the external battery and charging cradle are clearly visible in the image, and no corrosion or blackening has been detected.

Accessories and Battery Condition

The device’s accessories are vital for the set to remain operational, and the set appears complete:

• Battery Condition: The set includes an external white battery. Visual inspection revealed no signs of swelling, case opening, or liquid contact (leakage) on the battery. Although capacity information cannot be read due to small print on the label, its physical form is healthy.
• Adapters: The device has a large power adapter for home use (mains electricity) and a car cigarette lighter adapter for in-car use. No crushing, breakage, or stripping of external insulation was observed on the cables.
• Charging Cradle: The white station used to charge the battery independently of the device is present.

Label Information

The following details were observed on the labels of the product parts, but fine technical text (such as serial numbers) could not be fully read due to photo resolution:

• Adapter Label: A text block containing safety certification logos such as CE, UL, recycling symbols, and technical voltage values is present.
• Battery Label: Safety warnings, a CE mark, and recycling warnings are present on the white label.
• Device Panel: The model number “pM-KN03T” is clearly printed on the screen frame.

Screen Analysis

There is a monochrome (likely LCD) information display on the upper part of the device. The screen is off in the image, so the software version or operating hours cannot be seen. The icons on the keypad (Power, Plus, Minus, Alarm/Mute) indicate that the user interface is consistent with standard oxygen concentrator controls (flow level adjustment).

Documents and Usage Duration

No invoice, warranty certificate, or user manual for the product is present in the images. Since the screen is off, information regarding total operating hours cannot be obtained.

Potential Failure Risk

The product visually appears quite clean and well-maintained. The neatly coiled cables and the device’s storage within its protective bag indicate that the product has not been roughly used. As no visible cable stripping or connector damage is present, no immediate electrical connection risk is foreseen. The device’s condition can be described as “Good”.
