Product Details

LED Display Screen

This mini mobile oxygen concentrator features a 2.4-inch full-color LED HD display that clearly indicates real-time oxygen concentration, flow mode, and battery status. Designed with a minimalist interface, it includes a compact control panel with only four physical buttons for all operations. The seamless arrangement of the display and controls ensures intuitive and user-friendly operation.

Advanced Heat Dissipation System

The device is equipped with a perforated grid ventilation system on its side panel, which effectively maintains the core component temperatures within safe limits. Coupled with an intelligent thermal management module and strategically positioned vents, this optimized cooling design ensures stable operation during prolonged use while mitigating the risk of overheating.

Removable Battery

This portable oxygen concentrator is equipped with a 5000mAh rechargeable lithium battery, with a single battery providing approximately 3 hours of continuous oxygen supply. Its versatile power design allows for seamless operation through household wall outlets, car power ports, or battery mode in environments without electricity. The removable battery enables quick swaps for extended outdoor use, while a direct power connection ensures unlimited runtime when plugged in. Suitable for home care, long-distance travel, and outdoor activities, this device delivers reliable respiratory support 24/7.

Three Charging Modes:

• Lithium battery power supply
• A/C wall outlet power
• DC 12V power via car cigarette lighter port

Non-Slip Feet

The device is equipped with four high-density foam anti-slip feet at the base, ensuring stable placement on smooth surfaces such as desktops or car interiors. These antibacterial-coated feet provide both slip resistance and hygienic safety, preventing shifting or tipping during operation while enhancing stability for extended use.

PSA (Pressure Swing Adsorption) Technology

This device utilizes medical-grade Pressure Swing Adsorption (PSA) technology, employing a molecular sieve to accurately separate nitrogen and oxygen molecules from inhaled air, consistently delivering high-purity oxygen at 93% ±3%. It features an innovative integration of a nano-photocatalytic-activated carbon composite filter, which performs triple-stage air purification during oxygen production: intercepting fine particles, neutralizing harmful gases, and inhibiting bacterial and viral activity. This dual-technology safeguard ensures medical-grade air cleanliness, making it ideal for respiratory support in environments with air quality concerns.

Intelligent Oxygen Delivery with Dual Modes

This oxygen concentrator offers 1-5 adjustable intelligent modes to accommodate a variety of respiratory needs. Levels 1-4 utilize Smart Pulse Mode, which dynamically synchronizes oxygen release with inhalation by real-time monitoring of breathing patterns. This ensures precise delivery at the moment of inhalation, minimizing gas waste and enhancing breathing efficiency. Level 5 operates in Continuous Fixed-Flow Mode, consistently delivering oxygen at a rate of 20 cycles per minute (30 ml per cycle). This setting is ideal for users with irregular breathing patterns or compromised respiratory capacity. The dual-mode design balances energy efficiency with stability, effectively addressing oxygen therapy requirements across various scenarios—from daily wellness support to specialized care.

Altitude-Adaptive Oxygen Supply

By pressing the altitude mode key, the interface enters into the altitude mode.A blue prompt bar showing “altitude mode” appears at the lower right corner of display screen, and altitude icon and current altitude value are shown below the shift number. After entering the altitude mode, you can continuously press the key, the altitude value on the display interface is separately “3000m”, “4000m” and “5000m”, and then press the key to exit from the altitude mode. The device automatically compensates for atmospheric pressure variations at altitudes up to 5,000 meters (16,400 feet), ensuring stable operation and a continuous supply of oxygen to users even in high-altitude environments.

Multi-level Safety Alert System

Equipped with a multi-level safety alert system, this device immediately activates an audible buzzer alarm (a continuous “Di-” tone) upon detecting overheating, low battery, or compressor/fan malfunctions. These safeguards ensure operational safety and reliability in various scenarios, such as home care or outdoor use, while also extending the device’s operational lifespan.

Intelligent Overheating Protection

The device features an advanced overheating protection system that utilizes internal temperature sensors to activate safety protocols as soon as abnormal temperature increases are detected. If temperatures consistently exceed safe limits, the system initiates an automatic power cutoff and locks operation until the device cools down to a safe range. This mechanism effectively prevents component damage and mitigates operational risks, ensuring compliance with safety management standards for respiratory assistance equipment.

Low-Noise Operation

The device operates at noise levels below 60 decibels (dB), which is comparable to the ambient quietness of a library. With its optimized mechanical structure and airflow system design, it ensures smooth and silent performance. Even during nighttime use or in confined spaces, it minimizes disturbances, making it ideal for continuous oxygen therapy in both residential and public settings.

Ultra-Portable Design

This handheld mini oxygen concentrator weighs only 1.2 kg (2.6 lbs) and features a lightweight, compact design that makes it an ideal travel companion. With a user-friendly interface and portable size, it provides convenient oxygen support for individuals requiring respiratory assistance. Easily transportable during trips, outdoor adventures, or daily activities, its quick-response design ensures immediate access to oxygen whenever necessary.

Shoulder Bag

This portable oxygen concentrator is accompanied by a specially designed shoulder bag made from lightweight, durable materials. The ergonomic strap contours perfectly to the device for comfortable carrying. The interior includes shock-absorbent compartments and adjustable securing straps to provide stable protection during movement. Additionally, dual-layer storage pockets are available for backup batteries and accessories, enhancing convenience. Whether for daily commutes or outdoor adventures, this bag ensures secure transport and quick access to your oxygen concentrator wherever you.
