The EASYLONGER ES400 AIR is a compact and robust power bank designed for portability and durability. It features a clear digital display showing output voltage and battery percentage. The device includes multiple output ports to accommodate various devices:

• DC IN/OUT Port: Used for charging the battery and for connecting CPAP machines via the included DC cables. Supports adjustable voltage output (12V, 16.5V, 20V, 24V).
• USB-C OUT Port: 30W Power Delivery (PD) for fast charging compatible devices like laptops, tablets, and smartphones.
• USB-A OUT Port: 18W Power Delivery (PD) for charging smartphones and other USB-powered devices.
• DC 12V OUT (Car Socket) Port: 160W output for devices requiring a car cigarette lighter connection, such as air pumps or car refrigerators.

5. Setup

Before first use, fully charge your EASYLONGER ES400 AIR battery.

5.1 Initial Charging

Connect the included AC adapter to the DC IN/OUT port on the battery and plug it into a wall outlet. The digital display will show the charging progress. A full charge typically takes 4-5 hours.

5.2 Connecting to CPAP Machine

Figure 5.1: Included CPAP cables for various machine models.

Figure 5.2: Options for powering your CPAP machine.

The ES400 AIR comes with 4 specific DC cables for direct connection to popular CPAP models. Before connecting, ensure the correct voltage is selected on the battery to match your CPAP machine's requirements (12V, 16.5V, 20V, or 24V). Refer to your CPAP machine's manual for its specific voltage.

1. Direct Connection (Recommended): Use one of the included DC cables that matches your CPAP machine. Connect one end to the battery's DC IN/OUT port and the other to your CPAP machine.
2. Using a Cigarette Lighter Cable with a Voltage Converter (Sold Separately): For CPAP machines not directly supported by the included cables, you may use a cigarette lighter cable with an appropriate voltage converter connected to the battery's DC 12V OUT (car socket) port.
3. Using an Inverter (Sold Separately): For broader compatibility, an AC inverter can be connected to the battery's DC 12V OUT (car socket) port, allowing you to power your CPAP machine using its standard AC adapter. Note that using an inverter can decrease overall runtime due to energy conversion loss.

6. Operating

6.1 Powering On/Off

Press and hold the power button for a few seconds to turn the unit on or off. The digital display will illuminate, showing the battery level and output voltage.

6.2 Using Output Ports

• DC IN/OUT: After setting the correct voltage, connect your CPAP machine. The display will show the active output voltage.
• USB-C OUT & USB-A OUT: Simply plug your USB devices into the respective ports. These ports are always on when the unit is powered, and the LED display will light up once a device is plugged in.
• DC 12V OUT (Car Socket): Plug in your 12V car-compatible devices. This port is also always on when the unit is powered.

6.3 Pass-Through Charging

The ES400 AIR supports pass-through charging, allowing you to charge the battery while simultaneously powering your CPAP machine or other devices. This feature ensures uninterrupted power, acting as a backup power supply in case of a power outage. For CPAP machines, this functionality works directly with the included DC cables. If using a voltage converter or inverter, ensure they also support pass-through functionality.

7. Charging Options

Your EASYLONGER ES400 AIR offers versatile recharging methods:

• AC Adapter (Included): Connect the 40W AC adapter to a standard wall outlet. Fully charges in approximately 4-5 hours.
• Car Charger (Not Included): Use a compatible car charger plugged into your vehicle's 12V cigarette lighter socket. Fully charges in approximately 2-3 hours.
• Solar Panel (Not Included): The battery features built-in MPPT technology, supporting inputs up to 72W. An 80W solar panel can fully charge the battery in approximately 3-4 hours, depending on sunlight conditions.

8. Compatibility & Runtime

8.1 CPAP Machine Compatibility

Figure 8.1: Direct compatibility with included cables.

Figure 8.2: Broad compatibility with an inverter (sold separately).

The ES400 AIR is designed to be compatible with most CPAP machines on the market. The included DC cables provide direct compatibility with:

• ResMed AirSense 11, AirSense 10, AirCurve 10, AirMini, ResMed S9
• Philips DreamStation, DreamStation 2

For other CPAP models, compatibility can be achieved using a separate voltage converter or an AC inverter connected to the battery's 12V car socket output.

8.2 Factors Affecting Runtime

Figure 8.4: Comprehensive list of factors affecting battery duration.

The actual runtime of the ES400 AIR when powering a CPAP machine can vary significantly based on several factors:

• Humidifier and Heated Tube Settings: These features consume significant power. Turning them off or setting them to zero will greatly extend battery life.
• CPAP Pressure Settings: Higher pressure settings generally require more power.
• Ramp Up Function: Using this feature can affect power consumption.
• Altitude Compensation: If enabled, this feature may impact power usage.
• Mask Leaks: Significant mask leaks can cause the CPAP machine to work harder, consuming more power.
• Machine Type: Different CPAP models have varying power efficiencies.
• Use of Inverter: Using an AC inverter introduces energy loss, reducing overall runtime compared to direct DC connection.
• Ambient Temperature: Battery performance can be affected by extreme temperatures.
