- MAX Mode: Provides maximum cooling power for rapid temperature reduction. This mode consumes more energy.
- ECO Mode: An energy-saving mode that reduces power consumption while maintaining the set temperature. Ideal for prolonged use or when power efficiency is critical.
- To switch between modes, press the 'SET' button until 'MAX' or 'ECO' appears, then use the '+' or '-' button to select your desired mode.
Battery Protection Mode
The refrigerator features a 3-level battery protection system to prevent your vehicle's battery from running out. When the input voltage drops below a certain level, the unit will automatically shut off.

Image: A graphic illustrating the 3-level battery protection mode for the Alpicool CHS55. It shows a table with voltage reference points for DC 12V and DC 24V inputs, indicating the 'Cut Out' (shutdown) and 'Cut In' (restart) voltages for Low, Medium, and High protection modes. The image also shows the refrigerator placed in a car trunk, emphasizing its use in vehicles.
| Mode | DC 12V | DC 24V | ||
|---|---|---|---|---|
| Cut Out | Cut In | Cut Out | Cut In | |
| Low Mode (L) | 8.5V | 10.9V | 21.3V | 22.7V |
| Medium Mode (M) | 10.1V | 11.1V | 22.3V | 23.7V |
| High Mode (H) | 11.1V | 12.4V | 24.3V | 25.7V |
To adjust the battery protection mode, press the 'SET' button until the battery icon appears, then use the '+' or '-' button to select H (High), M (Medium), or L (Low). It is recommended to use 'H' mode when connected to a car battery to prevent discharge, and 'M' or 'L' mode when connected to an external power bank or solar system.
