Partying without a break in music is so possible with the Eton Rugged Rukus Solar Sound System that tries to stay powered up all the time. With its incredibly smart solar panel, the sound system draws its energy from the sun which helps it in never losing power during the day. In times when the sunâ€™s not around, the internal lithium battery comes into existence which provides it with a power backup of upto 8 hours. Again, if you still look for more power backup, you can also attach your smartphone charging cable on the USB port thus helping it to draw its power directly from the electric socket. Itâ€™s definitely a wireless sound system which makes it easily compatible with your smartphone or tablet music list and enables you to control the playlist too. An appropriate music system travellers can look forward to carrying during outdoor trips.
