A very handy product that is so useful! I bought this as for years I had to charge my ipod with my USB lead that came with the ipod when I bought it. I didn't realize you could buy these but so glad I did as every time I wanted to charge my ipod I had to switch my laptop on. With this you just plug it into a wall socket, connect the dock connection to your ipod as usual and leave it to charge. I also think it charges quicker and holds the battery life for a bit longer. Would definitely recommend!
