Abstract: In order to study the intelligent mobile power supply under the condition of temperature control，voice control，touch control and Bluetooth function，PCB board is designed with REC-V2 voice chip，microcontroller，ESP8266 WiFi module，HC-06 Bluetooth module，SD memory card，heating module and infrared ranging module. The shell of the prototype is made by 3D printing with PLA plastic. The control switch，voice control system and microcontroller are used to customize the working mode of the intelligent mobile power supply. The LED lamp and the heating pad are used to output light and heat source. Experiments with two different power supply modes，the household 220 V power supply and the vehicle 12 V power supply have proved that based on the existing performance of traditional power banks，the intelligent mobile power supply can be performed various tasks such as switching LED light sources between different color， heating and voice broadcast with user's needs by voice control，manual operation，and mobile phone remote control. It has certain practical value.
