RT 02 big size 4 inch portable speaker  

          Its size is not very large, and it is relatively easy to carry. When you go on a long journey, when you are looking for poetry and faraway places, it seems to be a very pleasant choice to bring this 10W RGB Bluetooth speaker.  When you go to the top of the mountain, there is soothing music playing, and the music and the wind are all around you, how happy it is. Due to space issues, it is equipped with a 1200 mah battery with a normal life of 3.5-4.5 hours.  This also lowers the cost and brings the price into the right range.
