All about the product
Power supply for ACER, DELL, PACKARD BELL 19V 1.58A ZM/ACE19158 New Mitsu laptop power supply for Acer, Dell, Packard Bell comes with ferrite filter and excellent protection against overvoltage, overheat, overload and overcharge. Acer, Dell and Packard Bell 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, which eliminates 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 protection test - the reaction of the power supply protection systems is checked due to a short circuit and a sudden voltage jump, simulated by applying a high voltage pulse to the input of the power supply. 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 source? DC (direct current) power supply parameters are usually indicated under the notebook computer on a sticker under the inscription INPUT. The supply voltage in V (volts) must match the one indicated on the notebook computer. The current A (amps) must be equal to or greater than the value specified by the laptop, this parameter represents the maximum current that can be charged to the power supply, the size of the load is determined by the laptop Power W (watts) is the result of multiplying the voltage and the current The shape and size of the plug - compare with the photo of the offered product and with the dimensions of the plug specified in the description; we can also determine according to the database of the power supply manufacturer
