While everyone worries about forgetting their passport, the most commonly forgotten items are actually chargers and power cables. Because we use our smartphones, smartwatches, and tablets right up until the moment we walk out the door, these items are often left plugged into the wall at home. Close runners-up include toothbrushes and basic medications (like ibuprofen, antacids, or specialized prescriptions). Many travelers also forget to pack a physical hairbrush or sunglasses, items that are part of a daily routine but easy to overlook when staring at a suitcase full of clothes. In 2026, another rising "forgotten item" is the portable power bank, which is essential for modern travel apps and digital boarding passes.
