This document describes a portable car refrigerator, model 541610, manufactured by Anhui Saichao Electric Co., Ltd. and distributed by SCHEUFER Technologies GmbH and VISHTEC UK Co. Ltd. The refrigerator is designed for efficient, energy-saving, and stable mobile refrigeration.
Function Description:
The refrigerator utilizes a high-quality DC inverter compressor and drive module to ensure efficient and stable cooling. It features a microcomputer intelligent control system for easy operation and precise temperature control. An innovative and intelligent independent dual temperature and dual control system allows the freezer and refrigeration spaces to be switched at will, accommodating various storage needs. It is compatible with multiple power inputs, intelligently identifying DC12/24V voltage, making it suitable for various scenarios including car, marine, home, and outdoor use. The device includes voltage detection and low-voltage protection functions to prevent over-discharge of car batteries. The inner tank is made of food-grade plastic, ensuring safety, leak-proof performance, and odor-proof properties. For convenience, it has built-in LED lighting for use at night and a high-definition LED digital display. Intelligent touch operation buttons and a keyboard child lock function prevent accidental triggering.

Usage Features:
- Opening and Closing: Connect the DC12/24V power supply. When in standby, "OFF" appears. Press and hold the "Power button" for 3 seconds to start. The display shows current temperature and operating mode. After a 1-minute delay, it enters cooling mode. To turn off, press and hold the "Power button" for 3 seconds when unlocked.
- Keyboard Lock/Unlock: If the child lock icon is lit, press and hold the "UP/DOWN" button for 3 seconds to unlock. The keyboard automatically locks after 30 seconds of inactivity.
- Compressor Working Mode: In the unlocked state, press the "Set button" to switch between "ECO" (energy-saving) and "MAX" (fast cooling) modes.
- Low Voltage Protection: The product has a low voltage protection function. If the battery voltage falls below the set value, the compressor automatically turns off to prevent over-discharge. An "E1" code will appear on the display. The default setting is "Mid-Range". To change this, unlock the keyboard, press and hold "Set button" for 3 seconds, release after a "di" sound, then briefly press "Set button" again. One of the battery protection level icons (L, M, H) will flash. Use "UP/DOWN" to change the setting.
- Battery Protection Levels:
- L: 12V disconnect 9.6V, 12V start 10.9V; 24V disconnect 21.3V, 24V start 22.7V
- M: 12V disconnect 10.4V, 12V start 11.7V; 24V disconnect 22.8V, 24V start 24.2V
- H: 12V disconnect 11.1V, 12V start 12.4V; 24V disconnect 24.3V, 24V start 25.7V
- It is recommended to set the protection level to "H" when using the refrigerator in the car to ensure normal car startup.
- Temperature Setting: In the unlocked state, press the "Set button" to select L or R temperature zones, then use "UP/DOWN" to adjust the temperature. The display will flash the current setting value, and temperature changes by 1 degree per press. Holding the button allows for quick adjustment. The set value is saved automatically if no change occurs within 5 seconds.
- Closing L/R Temperature Zones: In the unlocked state, when setting temperature, press "Set button" to switch between L and R zones. If an L zone is flashing, press the "Power button" to turn it off (displaying "OFF"). Press "Power button" again to return to normal temperature display. Repeat for the R zone. Note that L and R temperature zones cannot be closed simultaneously.
- APP Operation:
- Connect the refrigerator to power; the Bluetooth icon will flash.
- Download and install the Tuya Smart APP. Turn on Bluetooth on your phone and open the app.
- The device should be automatically discovered. Click "Add". If not, click "Add Device" and then "Add Manually" or wait for discovery.
- After discovery, click "Add".
- Once successfully connected, click "Done".
- The Bluetooth APP control interface will appear. If the Bluetooth connection fails, press "Settings" and "On/Off" simultaneously for three seconds until the Bluetooth logo resets and flashes, then reconnect.
Maintenance Features:
- Error Code Description:
- E0: Temperature sensor damaged. Solution: Check or replace the temperature sensor.
- E1: Input voltage too low. Solution: Check the input voltage.
- E2: DC fan overcurrent protection. Solution: Check the cooling fan.
