It's hard to predict what doomsday would really be like, but, excluding the possible doomsdays where you wouldn't want to live (nuclear fallout is nasty!)... There are two types of tech you might want to preserve: Things that will store information (survival guides, plant identification, maps) and things that will help with daily life (GPS watch, electric drill, night vision goggles, etc.) Focusing on storing information in a survival situation is smart. People would likely band together into groups, and if you can call up survival guides at a moment's notice, you'll be valuable. I'd buy 10 each(!) of: 1. The exact same model of cheap laptop on ebay with chargers (you'll need the chargers!) 2. AC inverter that can power an AC device from a 12v source (such as a car battery) You'll also need solar panels and if you can find a battery pack that can be charged by the solar panels, you'll want that too. Storing all of this in a self-storage unit is likely enough to survive an EMP. Don't believe the hype, EMPs will be blocked by a lot of normal buildings.
