Will using a higher-wattage power supply damage your laptop?
It’s completely safe to use a charger with more watts. This is due to the way the laptop is built, which allows the system to draw the most power possible. Since a higher-wattage charger can readily supply this power, there won’t be any problems. Hence ICFix Service provides Laptop chip-level training courses in Chennai.
An Overview of Watts, Amps, and Volts:
Think of electricity as water running through a pipe to understand the notion of Volts, Amps, and Watts. The amount of water flowing through a pipe is measured in amps, voltage measures the speed at which the water is pushed through the pipe, and watts measure the force the water exerts when it reaches the other end of the pipe.
Watts and Amps are Associated:
Volts and Amps are multiplied to determine Watts. Since 19V times 3.42A equals 65W, a 19V charger with that rating would be a 65W charger. If the voltage stays constant, the Watts increase as the Amps do.
A maximum rating applies:
A laptop charger’s Amps and Watts rating is its maximum output rating. This indicates that the charger can output all of the maximum Watts specified. i.e., it can exert a force of up to x Watts and x Amps through the pipe at the pressure (Volts) supplied by the charger.
The Warnings:
There are a few caveats, as I mentioned at the outset.
● The voltage needs to be identical to, or very close to, what the laptop demands. In general, we do not advise using a charger that provides more or less voltage than the laptop needs (1V or less). HP makes computers with voltages of 18.5V, 19V, and 19.5V, and we’ve never had an issue providing one of these chargers with any HP notebook. Although laptops typically require 20V, 19V chargers have never caused us any issues. However, you cannot use a 15V charger on a laptop that needs a 19V charger or the opposite.
● The output tip must coincide. Tips come in a variety of forms. There is the conventional barrel tip, which is a straightforward connector in the shape of a barrel with a hole in the center. These are quantified as 5.5mm x 2.5mm, which is the tip’s external and internal diameter. The connector won’t fit or will be too loose if these don’t match. Some chargers have a tiny pin in the center, while others (like those made by HP and Dell) contain what is known as a “smart tip”—a piece of circuitry that can communicate with the laptop to make sure the right charger is plugged in. Despite the fact that these tips are the same size, you cannot use a Dell charger on an HP laptop or the other way around.
● Polarity must coincide. To be honest, we have never encountered a laptop charger that is different from the way barrel connections typically have the negative on the outer sheath and the positive inside the inner hole. However, it’s always a good idea to check the polarity against that of the laptop or your original charger in order to prevent any damage to your laptop.
