CAIRE FreeStyle Comfort Portable Oxygen Concentrator Analysis Report

Device Identification

The device examined in the images is a “Portable Oxygen Concentrator” falling under the category of medical products. The product is a compact system designed to meet the oxygen needs of patients outdoors, operating on battery power without requiring a fixed electrical source. The system consists of a main unit, a detachable battery pack, and power adapters.

Brand and Model

Based on the data on the technical label located on the back of the device in Image 4, the brand and model information of the product have been definitively identified. The logos, design language (three wavy blue logo), and inscriptions on the label are as follows:

• Brand: CAIRE
• Model: FreeStyle Comfort Oxygen Concentrator

The product is an original medical device assembled in the USA (Ball Ground, GA) by CAIRE Inc.

Authenticity

Upon examining the barcodes on the device’s rear label, manufacturer address details (CAIRE Inc.), the “Assembled in USA” inscription, FCC ID (WAP2001) codes, and the print quality of the CAIRE logo on the front face, the product is determined to be 100% original. The label structure and CE (0459) certification marks confirm that the product is an official production compliant with standards.

Areas of Use

This device is used to enable the mobilization of patients requiring continuous or intermittent oxygen support due to COPD, respiratory failure, or various lung diseases. It is suitable for use at home, in a vehicle, or during air travel (thanks to the FAA approval stated on the label). It filters the air, separates nitrogen, and delivers concentrated oxygen to the patient.

Quantity Information

A total of 4 product parts have been identified within the set shown in the images:

• 1 CAIRE FreeStyle Comfort Main Device Unit
• 1 External Battery (Battery Pack – visible as a white block next to the device in Image 3)
• 1 AC Power Adapter (for electrical outlet – black boxed adapter and its cable)
• 1 DC Power Cable (for car cigarette lighter input – the round-tipped cable on the right in Image 3)

General Condition

The device is in good cosmetic condition. No yellowing is observed on the white plastic casing; its color is vibrant. Although it is a used (second-hand) product, no severe signs of wear have been found. The overall appearance of the device indicates that it is clean and well-maintained.

Physical Deformation

Upon detailed examination of the product’s outer casing:

• Casing: No deep scratches, cracks, or dents have been detected. Corners and joints are smooth.
• Grilles: No broken teeth are present in the ventilation grilles on the front upper section.
• Cleanliness: The device generally appears clean, with minimal dust accumulation.

Mechanical Components

Metal rings for a carrying strap are present on the top part of the device and appear robust. The covers for the air inlet/outlet ports on the bottom are in place. No broken parts were observed on the tabs of the battery pack in the images; its structure for seating into its slot is preserved.

Electronic Components

The keypad on the upper control panel (Plus, Minus, and Power buttons) is physically sound; there is no fading or depression on the buttons. No dangerous conditions such as crushing, breakage, or insulation stripping were detected visually on the AC adapter and its cables.

Accessories

The accessories provided with the product are as follows:

• AC Adapter: Black, standard appearance, used to power and charge the device from mains electricity. Its cables appear robust.
• Car Charging Cable: Black, with one end suitable for a car cigarette lighter input and the other end connecting to the device.
• External Battery: A white-colored power unit integrated into the bottom part of the device.

Battery Condition

The white part separated from the main device in Image 3 is the device’s battery pack. No physical swelling (battery swelling) or leakage marks are observed on the battery. Its outer casing is robust. However, battery performance cannot be measured solely by visual inspection; as the device was manufactured in 2019, age-related capacity loss in the battery cells is natural.

Label Information

Critical information read from the label on the back of the device (Image 4) is as follows:

• Serial Number (SN): CBB5219010105
• Reference Code (REF): AS200-202
• Input Voltage: 15 VDC / 10.0A MAX
• FCC ID: WAP2001
• Protection Class: IP22 (Protected against solid objects larger than 2.5mm and dripping water at a 15-degree tilt)
• Warnings: “RX ONLY” (Prescription Only), no smoking, no open flame warning icons are present.

Screen Analysis

On the upper part of the device (Image 2), there is an LCD information screen, likely colored. Since the device is off, the screen is black. No visible cracks, deep scratches, or ink bleeding (internal breakage) are observed on the screen. The screen’s “Peel off” protective film has been removed.

Size and Compatibility

Based on visual references (parquet flooring and cable proportions), the device is approximately 25-30 cm in height, falling into the “portable” (Portable Oxygen Concentrator – POC) class, and is sized to be carried over the shoulder like a bag. It is designed for adult use.

Year of Manufacture

On the rear label (Image 4), the date next to the “factory” icon, located immediately below the serial number and barcode area, is clear:

• Date of Manufacture: 2019-01-03 (January 3, 2019)

Usage Duration

As the screen showing the device’s total operating hours (O2 hours) is not on in the images, no data on usage hours is available. Based on the label, the device can be said to have a history of approximately 5-6 years.

Documents

No invoice, warranty certificate, or user manual is present in the images. Since the device’s manufacturing date is 2019, its legal warranty period (typically 2 years) has definitely expired.

Current Fault

During visual inspection, no evidence indicating the device is “Faulty” or “Out of Service” (such as breakage, missing parts, error labels, etc.) was found. Its physical integrity is complete.

Potential Fault Risk

Risk factors identified based on the images are as follows:

• Battery Life: As the manufacturing year is 2019, due to the chemical lifespan of Li-ion batteries, if the original battery has not been replaced, the charge retention time may have fallen below factory values.
• Molecular Sieve (Sieve Bed): The molecular sieves (zeolite columns) used in oxygen concentrators have a limited lifespan. For a device manufactured in 2019, the maintenance/replacement time for these columns may have arrived.

As no significant external rust or oxidation is observed, it appears to be a device in good condition, ready for use.
