I found this great invention that will keep your iPods or iPhones alive even you stay at the beach or the park for a long time.

Now staying outdoors with your family for a long time does not mean you can also lose touch with important emails or phone calls. Well, your time with your family is very precious but there will always be something important from work or your business, you may forget the laptop but you always have to bring your phone, just for emergencies.
