The new Mitsu Dell laptop power supply has a ferrite filter and excellent protection against overvoltage, overheating, overload and overcharging. Dell laptop chargers are designed for the most demanding users who value stress-free and convenient work. The quality of the product is confirmed by the following certificates: CE, ROHS, FCC and strict quality control, eliminating possible defects. QUALITY FIRST Temperature resistance - The influence of high and low temperatures on the resistance and electrical parameters of protection systems. the power supply unit is tested. Electrical test - checking the correctness of the electrical connections between the individual components of the power supply. Short-circuit and overvoltage test - the response of the power supply protection systems to short-circuit and sudden voltage surges simulated by providing a high-voltage pulse at the input of the power supply is tested. Final test - The output voltage level of the power supply is checked by running for one hour under constant load. The set includes a power cord, warranty card and user manual. How to choose the right power supply? The parameters of the DC power supply (DC DC current) are usually listed under the laptop on a sticker after the word INPUT The voltage V (in volts) of the power adapter must match the value specified by the laptop Current A (in amps) must be equal. up to or greater than specified on the laptop, this parameter represents the maximum current that can load the power supply, the load size is determined by the laptop. Power W (Watts) is the product of voltage multiplied by voltage. current. Please compare the shape and size of the plug with the photo of the offered product and with the dimensions of the plug specified in the description; we can also determine from the database of the power source manufacturer
