Please check if you are using it over thick clothing, ensure the blanket is firmly connected to the controller, and try setting it to the highest heat level.

If it hasn't been used for a long time, please charge it for 10 minutes to activate the battery. Also, try using a different charging cable or power adapter.

Please recharge the device, or let it cool down and restart. This is usually the normal operation of low-power protection, the auto-off timer, or temperature protection features.

Please fully charge the device before use, and remember to unplug the power bank after each use.

Please recharge the power bank first, ensure you press and hold the power button for 2-3 seconds, and check that all cables are securely connected.
