For air traveler, being stuck unexpectedly with chargers for overweight baggage on check-in can only add to the surly feelings.This Balanzza Digital Luggage Scale is a perfect option for avoiding overage costs when flying. Weighing in at less than a pound itself, Balanzza's compact digital luggage scale is small enough to weigh up to 100 pounds of suitcase, so you can reallocate the contents before going to the airport. To use it, loop the scale's strap around the suitcase handle and lift the scale and bag off the ground for a few seconds. Once the scale beeps, set the bag down and read the large digital display showing the total weight. Repack as needed to get the weight down.
