If you've got a Summer vacation planned, showing up at the airport with your phone not fully charged could be a dangerous idea. The Transportation Security Administration has implemented rules stating that if your phone can't be turned on at the airport , it may be confiscated. Breaking TSA's new cell phone regulations could lead to a serious inconvenience: traveling without your phone. So, when you're packing your bag  for your next vacation, make sure one of these handy battery packs or chargers is stashed in your carry-on.
