Can I Charge My Bluetooth Speaker Through a USB Port?

In the world of portable audio, Bluetooth speakers have become the go-to choice for many. Their wireless convenience and compact size make them ideal for everything from picnics and pool parties to backyard barbecues and even just chilling at home. But what happens when your speaker runs out of juice? Can you simply plug it into a USB port and get it charged up?

The answer, in short, is sometimes. While some Bluetooth speakers are equipped with USB charging capabilities, others are not. To determine whether your speaker can be charged via USB, you’ll need to consider a few factors:
