Types of adapters for laptops are those that operate on the principle of electromagnetic energy conversion with electronic circuits in combination With switching transformers, absolutely do not use adapters of conventional transformers (regulator ). Features that help you distinguish between light-weight switching adapters, small sizes, large currents and large supply voltages. If the specifications are equivalent to switching adapters, the regulator type will be three times larger, weigh a lot more and the input voltage is always fixed at a single level (220V or 110V).
