To achieve a freezing effect with the phone cooler, please ensure the following conditions are met:

Adapter voltage requirements: Use an adapter with an output voltage higher than 5V3A for the power supply.

Charging cable selection: Make sure to use the default charging cable we provide for connection.

Room temperature conditions: Ensure the room temperature during operation is below 25°C.

Important warning

Please note that this device is a phone cooler, not a professional ice maker. Avoid operating the device while unloaded for extended periods in an attempt to achieve the freezing effect, as this may cause damage to the device or pose a safety hazard.

If the product flashes, it indicates that the power supply is insufficient. You need to use a 5V3A plug to supply power and connect it to our charging cable. This is not a quality issue.
