You can be sure that you are getting high quality AC Adapter for your Sony , because all of our Sony Batteries and Battery Chargers are precision-engineered and rigorously tested for voltage, capacity, compatibility and safety to exceed original equipment manufacturer specifications.
What is the nominal voltage and current of Sony Laptop AC Adapter mean?
The nominal voltage of Sony Laptop AC Adapter power supply normally refers to the open circuit output voltage, that is a voltage value not take any load and without current output. Therefore, this can be considered as the output voltage limit of Sony Adapter. For the internal use of the initiative power supply unit or voltage regulator components of the benchmark, in general the use of high resistance DC voltmeter can directly measured the nominal voltage, even if the mains voltage fluctuations in a certain place, the output is also a constant value;
The current of Sony Laptop AC Adapter: Regardless of any Sony Laptop AC Adapter has a certain amount of resistance, so when the Laptop AC Adapter output current, the voltage drop in the internally , which is equal to the output current multiplied by the Sony power adapter resistance. Resulted in two things, one is the heat generated is equal to the square of the output current multiplied by resistance, so the power will be hot.
Purchasing OEM Sony Laptop AC Adapter vs. 3rd Party Laptop AC Adapter
Third party Laptop AC Adapter by us are usually lower in price and usually exceed the performance of OEM Sony Laptop AC Adapter. Many of our Laptop AC Adapter are 100% compatible with OEM Sony Batteries. We offer a superior warranty over the OEM manufacturer's warranty. Finally, we make warranty replacement on our 3rd party Laptop AC Adapter easier by dealing with you, the consumer, directly.
