I'll probably not hookup fridges or anything large like that. My laptop would be fine, it uses a switching power supply to 19V (though it charges of 12 to 24V just fine). Most of what I want to power basically uses a power supply to go to DC already including router and wifi, so it's not a problem, I just need to either find the right DCDC converter or solder one myself (I'm confident I can solder something together that should be able to hold 4 or 5 amps, above might need thicker copper plating on the PCB).
