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.
The Acer notebook power supply from Mitsu is equipped with a ferrite filter and excellent protection against overvoltage, overheating, overload and overcharging. Acer laptop chargers are aimed at the most demanding users, who appreciate stress-free and comfortable work. The quality of the product is confirmed by the following certificates: CE, ROHS, FCC and strict quality control eliminating possible defects.QUALITY BEFORE EVERYTHING Temperature resistance - The influence of high and low temperatures on the resistance of the protection systems and the electrical parameters of the PSU is tested. Electrical test - Testing the correctness of electrical connections between individual components of the PSU. Short-circuit and over-voltage test - The reaction of the PSU protection systems due to a short circuit and a sudden voltage jump simulated by supplying a high-voltage pulse at the input of the PSU is tested. Final test - The output voltage level of the UPS is tested by subjecting it to an hour-long continuous load. The set includes a power cord, warranty card and instruction manual.How to choose the right power supply?The DC supply parameters (direct current DC) are usually given under the laptop on the sticker after the INPUT sign The voltage V (volts) of the power supply should match the value given on laptop A current (amps) should be equal to or greater than the value on the laptop, this parameter means the maximum current that is allowed load the power supply, the laptop decides about the size of the load W power (watts) is the result of the multiplication of voltage and current The shape and size of the plug should be compared with the picture offeredcthe item and dimensions of the plug given in the description; we can alsodetermined on the basis of the PSU manufacturer's database
