7. Operating Instructions
7.1 Recharging the AP400
The AP400 offers four convenient ways to recharge:

- AC Wall Outlet: Connect the AC power cable to the AC Input port and a wall outlet. This is the fastest method for home charging.

- Car Charger: Use the provided car charger to recharge from your vehicle's 12V cigarette lighter port.

- Solar Panel: Connect a compatible solar panel (12-30V DC, 150W max) to the DC Input/Output port. Position the solar panel in direct sunlight for efficient charging.

- Generator: Connect the AP400 to a generator using the AC power cable.

7.2 Powering Devices
The AP400 can power up to 8 devices simultaneously, depending on their power consumption.

- AC Outlets: Press the AC Button to activate the AC outputs. Plug in devices requiring up to 500W total. The AP400 provides a pure sine wave output, suitable for sensitive electronics.
- USB-A Ports: Press the USB Button to activate the USB-A ports. Connect your USB-powered devices.
- Type-C Port: Press the USB Button to activate the Type-C port. Supports Power Delivery (PD) for fast charging compatible devices.
- DC Output: Press the DC Button to activate the DC output. Connect compatible 12V DC devices.
- Car Outlet: The car outlet can be used for devices that plug into a vehicle's cigarette lighter socket.
- Wireless Charging: Place your Qi-compatible device on the wireless charging pad on top of the unit. The wireless charging supports 5W, 7.5W, or 10W output.
7.3 Uninterruptible Power Supply (UPS) Function
The AP400 features a professional-grade UPS function with a rapid switchover time of less than 10 milliseconds. This ensures that sensitive devices like computers, servers, and medical equipment remain powered during an outage without interruption.

To use the UPS function, connect the AP400 to an AC wall outlet and then connect your devices to the AP400's AC outlets. In case of a power failure, the AP400 will automatically switch to battery power, providing continuous operation for your connected devices.
