Power Adapter ACER 19V 4.74A ZM/ACE19474 The new Mitsu Acer laptop power supply comes with a ferrite filter and excellent protection against overvoltage, overheat, overload and overcharge. Acer 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 resistances of protection systems and the electrical parameters of the power supply 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 source? DC power supply parameters are usually found under the laptop on a sticker behind the word INPUT The voltage V (in volts) of the power supply must match the value indicated on the laptop Current A (in amperes) must be equal. or greater than specified on the laptop, this parameter represents the maximum current that can be used to load the power supply, the load size is determined by the laptop. Power W (watts) is the multiplication of voltage and current Plug shape and size - compare with the picture of the offered product and with the dimensions of the plug in the description; we can also determine from the database of the power source manufacturer
