Party box with socket for charging battery device?

Hello, I'm not that good at this but is there a party box or Bluetooth speaker that has a socket where you can charge a battery-powered device?

My husband often works away from home with battery-powered devices and enjoys listening to music. He already has a few spare batteries, but they still run out too quickly. To avoid constantly driving home to charge a battery, I'd like to buy a device that functions like a power bank and, ideally, maybe even has a speaker. Is there such a thing relatively inexpensive?

Thanks for your help.
