I managed to ship the Core to a friend who will bring it to the Third World. As you may know we don't have 110v here, it's all 220v. The Razer Blade Stealth works fine since the Power Adapter handles all currents, all I had to do was change the cable. My family has brought some appliances like a Vacum cleaner, and a few cooking machines, and some of the work with transformers, other just by changing the cable. Most Desktop Power supplies have a switch to 220v. Does anyone know if the Core has this switch? If not, will I need a transformer?
