Most Bluetooth speakers, including all the models discussed in this article, can be used while charging. This feature is particularly useful for extended listening sessions or when you're low on battery but want to keep the music going. However, it's worth noting that some speakers might not perform at their peak while charging. Additionally, for the sake of long-term battery health, it's generally better to avoid frequent use while charging. Occasional use during charging is fine, but allowing your speaker to charge fully before unplugging it for use can help maintain battery longevity.
