A digital travel scale is travel journalist and owner of Carole Roseblat’s travel essential. “Digital is perfect. You can switch from pounds to kilograms. The hook is easy on/easy off. Just hook it onto your bag and lift. This way you’re not worried while traveling to the airport. And you’re not ‘that person’ who is opening their luggage and unpacking things on the airport floor. Unlike the U.S., many places have weight limits, even on carry-on luggage. While traveling in New Zealand, they actually weighed everyone’s carry-on bag while going through security. I carry it in my backpack, with all of my other electronics so, if the airport’s scale is weighing heavy (Maui was always known for this), I can whip my scale out and at least put up a good argument for my bag being within weight limits,” she says.
