I have not found any kind of "party-up" mode (as with Bluetooth speakers) either in the app or on the device itself.
I'm not familiar with this function via WLAN either.
However, the device can be found in the Home Assistant, if you can use it, but I haven't tried it.
The Kenwood CR-ST100S Silver is primarily designed for mains operation. Although it supports two AAA batteries, battery operation is not explicitly mentioned as an operating mode. It is therefore unlikely that the device is designed for battery operation.
No, battery operation is not possible, because the radio must be operated with 12V and 2A, it needs 24 watts.
Power consumption in standby mode Less than 0.9 Watt
Power supply 100-240V AC 50/60Hz
DC output 12V / 2A / 24W
The Kenwood CR-ST100S has a USB-A port, but this is mainly used as an input for charging devices or as an AUX input and not specifically for playing music from a USB stick. There is no explicit mention that the device can play music from a USB stick.
