    I built a site that helps you find which plugs you need for your trip▲7

    I made this simple site that tells you which travel adapter you need for your next trip. I found myself googling this info and always being linked to a random article that was super long. Decided to make this crisp page that gives key info above the fold. Built with NextJS + Tailwind. I'd love some feedback and what should I add?
