3.2 Power Connection
The cooler can be powered by three methods: 12V/24V DC (car/vehicle), 100-240V AC (home/mains), or a portable power station with solar panels.
- DC Power (12V/24V): Connect the provided 12/24V DC car power cable to the cooler's DC input port and then to your vehicle's cigarette lighter socket.
- AC Power (100-240V): Connect the provided AC adapter to the cooler's AC input port and then plug it into a standard wall outlet.
- Portable Power Station: Connect the cooler to a compatible portable power station using the appropriate cable.
3.3 Initial Use
Before first use, it is recommended to clean the interior of the cooler with a damp cloth. Allow the unit to stand upright for at least 6 hours after transport before plugging it in to allow the refrigerant to settle.
4. Operating Instructions
4.1 Control Panel Overview
The cooler features an intuitive control panel for manual operation. It typically includes a power button, temperature adjustment buttons (+/-), and a mode selection button.
4.2 Temperature Setting
- Press the power button to turn on the cooler.
- Use the '+' or '-' buttons to adjust the desired temperature. The temperature range is typically -20°C to 20°C.
- The display will show the current temperature and the set temperature.
4.3 Operating Modes (MAX/ECO)
The cooler offers two operating modes:
- MAX Mode: Provides rapid cooling for quick temperature reduction. Ideal for initial cooling or when ambient temperatures are high.
- ECO Mode: Optimizes energy consumption for extended operation. Suitable for maintaining temperature once the desired level is reached.
To switch between modes, press the mode selection button on the control panel or use the mobile app.
4.4 Dual-Zone Functionality
The 48L model features two independent compartments. The larger compartment (41L) can be set between -20°C and 20°C, functioning as either a freezer or a refrigerator. The smaller compartment (7L) maintains a temperature relative to the larger compartment, suitable for items that do not require freezing.
4.5 Smart App Control (WiFi/Bluetooth)
The cooler supports control via a mobile application (available for Android and iOS devices).
- Download the AAOBOSI app from your device's app store.
- For first-time use, a WiFi connection is required for initial pairing.
- Once paired, you can connect directly via Bluetooth without WiFi.
- The app allows you to monitor temperature, adjust settings, and switch modes remotely.
4.6 Battery Protection
The cooler includes a triple-level voltage protection system (Low, Medium, High) to prevent your vehicle's battery from draining. Adjust this setting based on your vehicle's battery type and usage.
