My IPod Shuffle wont charge or turn on...do I need to get a new one?...

Hi, I recently got a Ipod Shuffle for christmas. It came in a small box, with headphones and a USB cable. I don't know what generation it is, I guess 3rd or 4th, but honestly, I dont know. But I lost it and found it again about a week later. It was turned off. But it won't turn back on. Does it need to charge or do I need a new one? x😕
