I always forget to take my mini speaker to the park or just to visit a friend. So I benefit from both. The bottle itself holds about 16 ounces, which is the average volume of a bottle. I'm still testing how long it keeps my drink cold/hot. After charging, still check the battery life of the speaker. But overall I was impressed with the quality. It needs to be charged before use, and it didn't take long. It's definitely well made for the price considering my swell was $25 alone. It's great to get a decent sounding speaker!
