One-Way Time Machine

Your friend Dexter has always been a little strange. So when he spends weeks hiding in his garage and asking suspicious questions about history, you think nothing of it. Then he shows you what he’s been building: a genuine time machine. It works, too. Mostly. There’s only one small problem—it’s a one-way trip. Now you get to pick the year, choose your destination, and pack up to 50 kg of whatever you think you’ll need. Clothes, supplies, gadgets, souvenirs… perhaps a few things history definitely wasn’t expecting. Once the machine starts, there’s no going back. So, where—or rather, when—are you going? This is my first scenario made so any suggestions would be appreciated.
