A Solution Dedicated to YouReliability is crucial to you? Choose a Qoltec AC adapter dedicated to Samsung laptops. It is ideal for use at home or in the office, as a main or auxiliary power supply. It is made of the highest quality materials, and the technologies used in it will allow low power consumption and high efficiency. In the set you will find the power supply along with a velcro cable organizer, which will allow you to adjust the length of the cable to your needs.Safe power supply in a universal designThe power supply will ensure stable operation thanks to the manufacture of the highest quality materials and special protections:- Against overvoltage: protects against under- or over-voltage,- Against overloads: protects against overloading the power line,- Against short circuits: protects against short circuits in the power supply circuit,- Thermal: protects against damage caused by overheating. Fitting the power supply - we give a helping handMatching the right power supply to your laptop model is very important. The following points will dispel any doubts that may arise when choosing equipment: The basic parameters you will read from the label on the bottom of the laptop are: POWER (W), VOLTAGE (V), AMPERAGE (A).1. Power (W) - this number indicates the minimum value that a new power supply should have. Nothing prevents you from using a product with a higher wattage. This will put less load on it and, consequently, it will heat up less.2. Amperage (A) - here, as in the case of POWER, the value on the new power supply can be equal to or higher than that stated on the laptop's rating label.3. Voltage (V) - the number next to this parameter is more strictly required. Only a variation of +/- 0.5V is allowed.The last and equally important issue is the plug. Without it, not a move! Here there is no deviation, it is necessary that it is identical to the original. The size given means the outer diameter and the inner diameter of the pin. If a comparison based on the picture shown is not enough, it will be necessary to measure it, which will ultimately reassure you in your choice.
