4. Digital Luggage Scale ($20 or less)
The airline baggage restriction game is real. A lot of folks have had their vacation budgets dipped into before even boarding their flight because they packed recklessly. Nobody wants to be the struggling schlep shuffling belongings from suitcase to carry-on while checking in for a flight. And literally NO ONE wants to pay a penalty for checking overweight bags. A digital travel scale can prevent those things. These devices attach directly onto luggage so users can see firsthand if repacking is in the cards.
