Review on 🔊 TEWELL Mini Sound Bar: USB Battery Powered Projector Speaker with Strong Bass for PC, Gaming, Tablets and Cellphone by Jacob Seymour

This speaker was a great purchase for my Haier TV. I'm not sure about the battery life yet. But the sound is great and the price is great! At first I tried using an RCA cable and couldn't get any sound. Then I found a small round entrance on the back of the TV. I used a cable with a 3.5mm connector on both ends. Then it started working very well. And my TV remote even controls the speaker. I still don't know about battery or Bluetooth?
