So the original laptop charger broke and I switched to a charger from a laptop that I no longer use. The specifications from each are:
Original Input:AC 100-240V 1.5A 50-60Hz Output: DC 19V 3.42A
Other Charger Input: AC 100-240V 1.5A 50-60Hz Output: 20V 3.25A
Yes, the polarity is the same.
Also, the wattage has a difference of .02 from what I understand. Is wattage ever important, and more specifically, a wattage difference of that size.
Feel free to ask me any other questions about the chargers and I'll answer them to the best of my ability.
