Question

Can I use a charger that has 65w on my dell inspiron 15 5570 that normally takes 45w? The input of my laptop is 19.5V---3.31A/3.34A, and the output of the charger is 19.5v----3.34A. Write the answer in 3-5 sentences. (5 points)

Answer 1

You can use a 65W charger on a Dell Inspiron 15 5570 if the voltage matches at 19.5V and the charger's amperage is sufficient, as it will not overload the circuits.

Step-by-step explanation:

Yes, you can use a 65W charger on your Dell Inspiron 15 5570 that normally takes 45W, provided that the voltage matches, which is 19.5V, and the charger can supply at least as much current as the laptop draws, which is 3.31A/3.34A. The output of your charger at 19.5V—3.34A aligns with the laptop's requirements. The charger can supply more power than needed, allowing the battery to charge safely without overloading the laptop's circuits.

Answer 2

Yes, as the values are very similar and will generally be fine.

Step-by-step explanation:

In general, it is safe to use a charger with a higher wattage than the one specified for your laptop as long as the voltage and amperage ratings match or are very close. In this case, since the input of the Dell Inspiron 15 5570 is 19.5V with an amperage rating of 3.31A/3.34A, and the charger you are considering has an output of 19.5V with an amperage rating of 3.34A, these values are very close and it should be safe to use the higher-wattage charger. However, using a charger with a much higher wattage than the one specified for your laptop, or one with significantly different voltage or amperage ratings, could potentially damage your laptop or cause a safety hazard.
