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?

Plug-in solar panels (no electrician needed) have just become legal in the UK and will go on sale soon. Helios estimates how much electricity a typical installation could generate at a given address and what that's worth against your tariff. It uses UK government LIDAR data to reflect the actual skyline, so it knows whether there's a building or a hill blocking the sun. Caveats: - Outside LIDAR coverage (most of Scotland and Wales) it falls back to a synthetic horizon (less accurate). - Trees and recent developments (post-2022 or so) may not be in the data, and some address placements could…

Hello HN, A year ago, I started the journey to create what we call a Switchless eSIM for travelers. The problem we’re solving comes from first-hand experience with accessing data while traveling overseas. The old methods like swapping SIMs, paying high roaming fees, or relying on WiFi are inconvenient and costly. Our solution is a single eSIM that you install once, then buy data for any country you travel to, and get connected instantly. Our app will be live in the next few days (hopefully), so for now, it’s just web. I would love to know if you’ve used eSIMs when travelling overseas and…
