Longfian Portable Oxygen Concentrator Analysis Report

Overview and Product Description

The images show one Longfian brand portable oxygen concentrator and various accessories belonging to this device. The product is a medical device designed for users requiring respiratory support, suitable for mobile use. The device’s overall design features a compact and modern structure. The package contents appear quite rich, including components that enable the device’s use in various environments.

All parts shown in the image are listed below:

• 1 Longfian brand portable oxygen concentrator
• 1 specially designed black carrying bag with a shoulder strap for the device
• 1 external battery
• 1 wall-type (AC) charging adapter and power cable
• 1 car cigarette lighter (DC) type charging adapter
• 1 black accessory bag
• 1 Medi-Tech branded, unopened oxygen tubing (Oxygen Tubing)
• 1 piece of protective foam packaging

Physical Condition

The general condition of the device and its accessories is very good. Based on visual inspections, the product is believed to have been used very little or not at all. No yellowing, discoloration, or significant wear has been observed on the device’s outer casing.

Casing and Exterior Surface: There are no visible scratches, dents, cracks, or stains on the device’s white and grey plastic casing. Its surface has a clean and smooth appearance.

Mechanical Components: No breakage or deformation has been detected in mechanical parts such as the control buttons, screen bezel, and ventilation grilles on the carrying bag. All parts are original and in place.

Accessory Examination

The accessories provided with the device appear to be a complete set. The carrying bag is perfectly compatible with the device’s dimensions, and it is clean and undamaged. There are no signs of crushing, breakage, or damage on the power adapters and cables. The fact that the oxygen tubing is in its sealed packaging is a significant advantage for hygiene and suggests that the product is unused. No adverse conditions such as swelling, leakage, or impact marks have been observed in the physical structure of the external battery.

Label Information and Technical Details

A detailed examination of the product’s casing did not clearly reveal a label indicating the model name or serial number. Only the Longfian brand logo is clearly visible on the main unit. The packaging of the oxygen tubing, included among the accessories, bears the “Medi-Tech” brand and the inscription “Oxygen Tubing”, but technical codes such as REF, LOT, or serial numbers on the packaging labels cannot be read due to photo quality. Since the device’s screen is off, no analysis of menus or warning messages could be performed.

Malfunction Status and Potential Risks

The visuals do not show any evidence of an existing malfunction (e.g., broken parts, error messages on the screen) on the device. Considering the overall cleanliness and undamaged state of the product and its accessories, no potential malfunction risk stemming from its physical condition is observed. The device gives the impression of being well-preserved and maintained, which indicates the potential for long-term and trouble-free use.
