Etekcity Luggage Scale ($12)

"My luggage scale is probably my favorite travel purchase to date," Mansel says. "I packed a smaller suitcase on a recent trip to London, but I was still concerned the contents of the bag had pushed it over the weight limit. The morning before my flight, I quickly weighed the suitcase and felt a sense of relief when I saw the numbers flash '42.' Anything over 50 pounds could have resulted in the completely avoidable overweight luggage fee."
