Quick Answer: What Is The Difference Between 65 Watt And 90 Watt AC Adapter?

Can I use a charger with higher amperage than the original?

Your computer will use more power, in the form of higher amperage draw, when it’s working hard than when it’s not.

(Voltage remains the same regardless.) Thus, as long as you replace your power supply with one capable of providing as much or more amps than the previous supply, you’ll be fine..

Can I use a 60 watt charger on my MacBook air?

Answer: A: You can use it. “Power adapters for Apple notebooks are available in 45W, 60W, and 85W varieties. … You can use a higher wattage adapter without issue, but doing this won’t make your computer charge faster or operate any differently.

What is the difference between 45w and 65w charger?

You can definitely use the 65W charger. The brick will be a little larger and heavier and it will charge your battery a bit faster. The plug and the voltage are the same so it works with your laptop fine.

Can a charger be too powerful?

It is actually more dangerous to use a charger that is under rated because it puts a larger load on the charger than it is capable of. A device will “try” to charge at its rated current and if the charger is not rated high enough it can fail.

What happens if you plug in wrong voltage?

It will lead to electrical burned and may cause serious consequences such as fire if the input voltage is higher than the normal. But if the input voltage is below the rated voltage, the electrical appliance can’t work normally or simply failed to work, and it may also cause damage to the motor.

Can you use a 90 watt adapter on a 65 watt laptop?

Yes, you can use a 90 watt ac adapter, a.k.a power charger, for your 65 watt-compatible laptop. It will actually charge your battery faster. But, and this is a big but, you cannot use a 19 Volt ac adapter on an 18.5 Volt-laptop.

Can I use a 90w adapter on a 45w laptop?

If the output voltage is the same, you can use a 90W charger on a 45W laptop BUT cannot use a 45W charger on a 90W laptop. On the condition of same voltage, laptops and other devices will never overpowered. The amps you saw is the maximum one adapter is capable of, not the rated current.

What happens if I use the wrong voltage adapter?

Voltage too high – If the adapter has a higher voltage, but the current is the same, then the device will likely shut itself off when it detects an overvoltage. If it doesn’t, then it may run hotter than normal, which can shorten the life of the device or cause immediate damage.

Can I use a charger with higher wattage?

Yes, Your laptop has been designed to draw up to a certain amount of power when running at full power. … This means that you can quite safely use a charger with a higher wattage (or amps) rating as the laptop will only ever draw the amount of power required at the time.

Can I use a 45 watt charger on a 65 watt laptop?

As long as it is the same voltage and connector type you can use a higher watt adapter. It will charge the battery a bit faster but other than and the size of the brick you will see no difference. The laptop will only draw the current it needs while running.

Can I use a 90 watt charger on a 120 watt laptop?

When the current is less than the rated value, the output voltage is higher. In the case of Laptops the regulation is probably in the Laptop and if that is the case then no problem using the larger (120 Watt) as the current (output power) will be the same for either the 90, or 120 Watt brick.

Can I use a 60w charger instead of 45w?

You can always use an adapter that has a higher power rating than is required as long as the voltage rating is the same. … Power adapters for Intel-based Apple notebooks are available in 45W, 60W, and 85W varieties.

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.

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 I use a 90 watt charger on a 130 watt laptop?

Generally the answer is yes, but it won’t supply enough power to charge the battery while you’re using your laptop. This will probably invalidate your warranty and could cause damage to your laptop, but the changes for that are small.

What Watt is fast charge?

Standard chargers that come with iPhones and older Android phones carry 1 amp of current and put out 5 watts of power. New rapid chargers with technology such as Quick Charge support 2 amps and 12 watts or more, potentially charging your phone up to four times faster.

What is the difference between 65w and 90w AC Adapter?

The 90W or 65W can be used on either of the 6cell or 9cell battery optioned Dell’s. However, the main difference is charge time. The 90w will charge your battery much faster than the 65w charger.

Can I use 85w charger instead of 60w?

Yes, with a caveat. The 85W adapter can be used inconsequentially with both models. It will provide ample power to both the MacBook Pro and MacBook, and will not damage the latter despite a higher-than-necessary wattage. … Note, however, that the 85W adapter will not charge a MacBook any faster than the 60W adapter.

Can I use a 19v charger for a 20v laptop?

Yes: technically it can be used, but you need a higher amount of power (watt). if the adapter is 19V 6A, it might start the PC but you will have strange side effects.
