Can I use a 130w adapter on a 65w laptop?
The laptop will only draw the current it needs so you will not fry anything. You can use an adapter with more amps and the same voltage and the same physical connection without any problems. It will even charge the battery faster.
Can I use a 60w charger instead of 45w?
Power adapters for Intel-based Apple notebooks are available in 45W, 60W, and 85W varieties. … You can always use an adapter that has a higher power rating than is required as long as the voltage rating is the same.
Does higher watts mean more power?
The Wattage of the light is the amount of energy it takes to produce a certain amount of light. The higher the wattage, the brighter the light, but also the more power it uses. … 100 Watt incandescent lamp produces 1700 – 1800 lumens and uses 100 Watts of energy per hour.
Can a bad charger ruin a laptop?
However many laptop manufacturers manufacture laptops that can use multiple different chargers, and vice versa. Just make sure the output supply voltage is almost the same, and the output current either greater than or equal to the original. Even a poor quality adapter is very unlikely to spoil the laptop.
Is it safe to use lower wattage charger for my laptop?

What happens if you use the wrong charger for your laptop?
Using a charger with the wrong voltage rating can potentially damage your laptop. This is typically caused by too high voltage. … Using a charger with too low current rating might fry the power supply, but not the laptop. As the difference in voltage in this case is small, it should be OK.
Can a charger be too powerful?
Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device places on the charger.
