Inogen One G5 Oxygen Concentrator Analysis Report

Device Identification

The main product shown in the visuals is a portable oxygen concentrator that falls under the medical electronic category, separating ambient air to provide concentrated oxygen to the patient. A carrying bag and power transfer accessories are also provided as a set with the device.

Brand and Model

The product’s upper control panel and the technical label on its rear surface have been examined in detail. Based on the blue “INOGEN ONE G5” inscription on the front of the device and the “INOGEN ONE G5 OXYGEN CONCENTRATOR MODEL IO-500” text on the rear label, it has been determined with 100% certainty that the product’s brand is Inogen and its model is One G5 (IO-500).

Areas of Use

This device is used for oxygen therapy for patients suffering from COPD (Chronic Obstructive Pulmonary Disease), pulmonary fibrosis, or other respiratory insufficiencies. Its portable nature, in particular, allows patients to gain freedom of movement by receiving oxygen support outside the home, during travel, or inside a vehicle. The car charging kit in the visuals supports the product’s mobile use purpose.

Originality

The casting quality of the device’s body plastic, the orderly placement of logos, the symbols on the keypad, and the format of the informational label on the back fully comply with manufacturer standards. Furthermore, the embossed “inogen” logo on the carrying bag proves that the accessory is also original. Visually, the product is an original Inogen production.

Quantity Information

A total of 5 items are included in the set in the visuals:

• 1 Unit Inogen One G5 Oxygen Concentrator Main Device
• 1 Unit Original Inogen Carrying Bag
• 1 Unit AC Power Adapter (Adapter Block)
• 1 Unit AC Power Outlet Connection Cable
• 1 Unit In-Car Cigarette Lighter Charging Cable (DC)

Overall Condition

The product, in its overall appearance, is in an extremely clean, well-preserved, and lightly used condition. Even if evaluated as second-hand, it is cosmetically “near new.” No significant signs of use were found on the device.

Physical Deformation

Upon detailed examination of the device’s white hard plastic casing, no impact marks on the corners, cracks in the casing, significant deep scratches, or abrasion marks were observed. No yellowing or fading of its color was detected. The outer surface appears hygienic and smooth. No accumulation of dirt or dust was observed in the air intake grilles.

Mechanical and Electronic Components

The control panel (LCD screen bezel and keypad) on the upper part of the device is intact. There are no tears or fading on the buttons (+, -, On/Off, Alarm, Volume), which are thought to be made of silicone. The metal oxygen output cannula (barb) is straight; there is no bending or breakage.

Accessories

The black carrying bag included in the set is an original product of the brand. The bag’s stitching appears robust, and there are no tears in the mesh parts. The carrying strap hooks are metal and appear sturdy.

Upon examination of the cables:

• The socket ends of the car charging cable (DC) are clean, and there is no peeling or crushing in the cable insulation. A CE mark is present on its label.
• No cracks or heat-induced deformation are observed on the casing of the mains power adapter (AC).

Battery Status

In these models (Inogen One G5), the battery is a modular part that clips into the base of the device. The visuals show that the lower white part of the device is attached. This indicates that a standard battery (“Single Battery” or “Double Battery”) is installed on the device. No swelling of the battery or openings at the casing joints were detected.

Label Information

The data read from the label on the back of the device is as follows:

• Brand/Model: INOGEN ONE G5 / MODEL IO-500
• Manufacturer Address: INOGEN INC. 326 BOLLAY DRIVE, GOLETA, CA 93117, USA
• Barcode (Possible UDI): (01)00817131020162(21)20160341-EU
• Input Power: 13.5 – 15.0 V / 120W
• Certifications: CE, IP22 (Water droplet protection class), Waste bin symbol (WEEE compliance)

Screen Analysis

Since the device is in the off position in the photos, the screen is not active. However, no impact marks that could cause cracks, fractures, or dead pixels are observed on the screen surface (“glass” or protective plastic). The panel is in a clean condition.

Potential Fault Risk

As a result of the visual analysis, no findings were encountered that disrupt the physical integrity of the device’s casing or connection points. There is no evidence that the device has been exposed to liquid or dropped. Therefore, based on the visible physical condition, the risk of a sudden fault is low, and the device’s condition is reassuring.
