Can I Use A 45w Charger Instead Of 60w?

What is the difference between a 65w and 90w power 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 a 45w charger instead of 65w?

If the voltages match, the 45W should just charge a bit slower than the 65W. I would refrain from running anything heavy though, as it may be more load than the adapter can handle and it will drain the battery as well.

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.

Is it bad to have a higher watt PSU?

Yes. Overbuying a higher wattage rating than you need doesn’t provide any performance benefit, it just costs money. … No, using a higher wattage PSU than you need won’t hurt anything.

Can I use a higher wattage charger for my phone?

YES, you can use any power charger for your mobile, BUT, it will only work if the charger output is 5volts. Charger output anything other than 5 volts will damage and burn your phone. Like if you use 9v or 12 volts.

Can a 65w charger for 45w laptop?

Yes. Wattage is a measurement of how much power a supply CAN generate, or how much your device DOES consume. The wattage of your power supply is a rating of the maximum power that can be drawn down from it; if your computer requires 45w but your supply can provide 65w, you will be fine.

Can I use a 45w charger instead of 90w?

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.

Can I use a 90 watt charger 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 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.

Does the wattage of a charger matter?

Watts are supplied “on demand” to the battery that’s being charged, so even if you’re over the device’s limit, it doesn’t cause problems. … A laptop will typically call for watts between 45 and 100. Not all chargers will list the watts, but if the amps and voltage match, you’re usually in the clear.

Do all HP Chargers work for all HP laptops?

In most cases, the current line of HP computers will share the same AC adapter (charger). There are a few exceptions to this rule but generally HP laptops will share chargers with other HP laptops that were introduced in the same time frame.

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.

Is 600 watt power supply enough?

But even with several hard drives and a decent Intel or AMD CPU, a 600W power supply is sufficient for most single GPU configurations. For multi-GPU systems, we typically recommend at least an 850W PSU, with 1000W (or more) needed for dual GPU configurations.

Can the wrong charger ruin your laptop?

Using a charger with the wrong voltage rating can potentially damage your laptop. This is typically caused by too high voltage. But using a charger with too high current won’t damage your laptop. Using a charger with too low current rating might fry the power supply, but not the laptop.

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’s the difference between 45w and 60w MacBook charger?

For instance, the MacBook Pro 13 inch uses a 60W MagSafe, but you can use an 85W MagSafe to charge or power it (although it will not charge any faster). You should not use a 45W with the MacBook Pro 13 since that is lower than its 60W requirement.

What happens if PSU wattage is too high?

There is no truth to the myth that a large wattage power supply will force too much power into your devices causing overheating and burnout. The power supply will only provide the needed wattage. For example, a device that needs 50 watts will only get 50 watts from a 250 watt supply, not the entire 250 watts.
