The product examined in the visuals is a portable (mobile) Oxygen Concentrator device designed for individuals requiring respiratory support. The device is a medical equipment that takes ambient air, separates nitrogen, and provides high-concentration oxygen to the user. The product is battery-operated and optimized for travel and outdoor use.

Brand and Model

As a result of detailed analysis of the logo on the front face of the product and the technical label on the back, the brand and model information has been definitively identified as follows:

• Brand: LONGFIAN
• Model: JAY-1000P
• Manufacturer: LONGFIAN SCITECH CO., LTD

As clearly stated on the rear label, the product’s model number is JAY-1000P. Additionally, importer company information is also present on the label.

Originality and Origin

The printing quality of the brand logos on the device, the placement of the technical label, and the CE certification marks on the label indicate that the product is an Original Longfian production. The label includes the phrase “Made in China” and the manufacturer’s full address (Baoding, Hebei, China), which matches the brand’s official manufacturing center.

Overall Condition and Cosmetic Inspection

Visually, the product appears to be in second-hand but very clean and meticulously used condition. Detailed physical analysis notes are as follows:

• Outer Casing: No visible cracks, breaks, deep scratches, or sun damage (yellowing) have been detected on the white plastic casing. The gray control panel and base strip are very clean.
• Keypad: No fading or wear is observed on the “On/Off” and directional keys on the control panel.
• Metal Parts: The oxygen outlet port (nozzle) is not rusted and retains its shine.
• Cosmetic Evaluation: The device has a high cosmetic score, almost qualifying as “like new” condition.

Areas of Use

This device is manufactured to meet the oxygen needs of patients suffering from COPD, pulmonary fibrosis, or other respiratory insufficiencies. Thanks to its “portable” nature, it is suitable for:

• Daily home use,
• In-vehicle travel,
• Walking or outdoor activities.

Technical Specifications and Label Information

Technical data and identification codes read from the silver label on the back of the device are listed below:

• Device Type: Oxygen Concentrator
• Serial Number (SN): MZJ2P00704
• Input Voltage: 100-240V, 50/60Hz (Universal voltage compatibility)
• Power Consumption: 90VA
• IP Protection Class: IP21 (Protected against vertically falling water drops)
• Barcode: 6 934726 614149

Screen Analysis and Usage Statistics

In the visuals, the device is shown in working condition. The LCD screen appears clear, bright, and free of pixel errors. The information on the screen is as follows:

• Graduated Flow Setting: The screen visuals show the device operating at different setting levels (e.g., level 2 and level 5). This indicates that the device can deliver oxygen in a graduated manner in pulse-dose mode.
• Total Operating Hours: The bottom part of the screen displays “0536H”. This indicates that the device has operated for a total of 536 hours throughout its lifespan. Considering that oxygen concentrators typically have a lifespan of thousands of hours, 536 hours is a very low usage time and technically confirms that the device is “lightly used”.
• Battery Indicator: The battery charge level (81% in the visuals) is shown instantly in the upper left corner of the screen.

Battery and Power Supply Condition

The externally removable and attachable lithium batteries are shown in detail in the visuals.

• Number of Batteries: 2 battery units are visible in the visuals (based on the image of batteries placed one on top of another).
• Battery Model: JAY-202D
• Capacity and Values: Lithium Battery, 14.8V, Nom 6.7Ah, 99.16Wh.
• Compatibility: The 99.16Wh value indicates that the batteries are generally designed to comply with airplane travel restrictions (under 100Wh) (however, airline rules should still be checked).
• Condition: Battery labels are clean; no oxidation or damage is observed on the connection pins. There are no signs of swelling in their casings.

Accessories and Package Contents

The accessory set provided with the product is quite comprehensive. The total parts count and analysis from the visuals are as follows:

• 1 Piece LONGFIAN JAY-1000P Main Unit
• 1 Piece Black Carrying Bag (Special design with shoulder strap and air vents)
• 1 Piece Accessory/Battery protection bag (Small size, zippered)
• 2 Pieces Rechargeable Lithium Batteries
• 1 Piece AC Power Adapter (White, brick-type)
• 1 Piece Socket Converter Head (European type plug tip attached to the adapter)
• 1 Piece DC/Power intermediate cable (thin white cable)

Mechanical and Electronic Components

Mechanical: The device’s air intake/outlet grilles appear clean. The carrying bag’s zippers and stitching are sturdy.

Electronic: The working condition of the LCD screen, the ability of settings (from 2 to 5) to change when buttons are pressed, proves that the electronic board and control panel are functioning flawlessly. No “Service” or “Alarm” light is illuminated (Only the green LED indicating power/operating status is active).

Potential Condition Assessment

As a result of the examinations conducted, no signs of breakage, impact, or functional malfunction were found on the device. The low usage time of 536 hours indicates that the majority of the device’s motor and sieve bed lifespan has not yet been consumed. Its general condition is ready for sale or use.
