A 3-pin power cord is a standard power cable used to connect electronic devices to a grounded electrical outlet, commonly for computers, monitors, and printers. These are widely available for purchase from various online and physical retailers. 

A 2-pin power cord is an electrical cable used for low-to-medium power devices that do not require a ground connection, commonly used with laptops, printers, TVs, and gaming consoles. 

The IEC 60320 is a set of international standards that define non-locking appliance couplers for connecting power cords to electrical devices, ensuring global compatibility and safety for equipment operating up to 250 V AC and 16 A. These standards use a system of "C" numbers (e.g., C13, C14) to identify matching connectors and inlets

When choosing a power strip, consider the number of outlets, presence of USB ports, cable length, and protection features like surge and overload protection. Your best option depends on whether you need a basic multi-plug outlet, a surge protector for electronics, or a smart strip with extra features. 

The C19 is a type of female, three-wire connector designed to handle high-current applications, primarily found on computer servers, large network equipment, and power distribution units (PDUs). It is part of the IEC 60320 standard and is rated for a higher current (typically 16-20A) than the more common C13 connectors found on desktop PCs.
