Quick Answer: Can I Use A 90w Charger Instead Of 45w?

Will a 65w charger work instead of 45w?

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 90w adapter instead of 120w?

Not recommended. It can run at reduced performance, not charge the battery at all while on, and the most dangerous of all, running hot. It needs 120W?

What happens if I use a lower wattage laptop charger?

The immediate consequence of the above will be that the battery will charge slower when charged by a lower watt charger, but in some cases if the watt rating is so small that it is less that the power consumed by the laptop while operating your laptop will discharge even when plugged in.

Can I use a 19.5 V charger on a 19v laptop?

Voltage: 19.5V and 19V is a relatively small voltage difference. It is most probably safe to use as long as: The current of the charger is the same or higher than that of the laptop. … The output power (Amps * Volts) of the original and the new charger differs in 0.6 Watts, the 19.5V charger having more output power.

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.

Can a 65w charger for 45w laptop?

Yes, Your laptop has been designed to draw up to a certain amount of power when running at full power. … If your laptop was supplied with a 65W charger we know that the laptop will never draw more than 65W, so you can use a 65W, 90W,120W, 150W, 180W, 240W or higher charger.

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 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?

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.

Can I use 65w charger instead of 135w?

If its original charger is a 130W adapter, then no, a 65W wouldn’t work. It might work entirely by coincidence (the plugs are the same and the computer somehow can operate at a much lower wattage, but that is like jumping into a dark room and trusting on blind luck that i’s not a spiked pit at the bottom.

Is it OK to use a different laptop charger?

The short answer is; No. You should never intentionally use another laptop’s charger on your laptop. It doesn’t matter if you’re in a pinch or if your battery is about to die. Plugging a different charger that isn’t meant for your specific model will not lead to anything good.

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 I use a 60w charger instead of 45w?

here’s the definitive answer: YES, you can use a higher rated power adapter with your MBA (or whatever) with no ill effect. … in the reverse case, if you use too low a wattage adapter (e.g. 45W one on a MB Pro), there won’t be enough current to charge the battery, although you can run it off AC power while plugged in.

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 90w adapter on an 180w laptop?

If the voltage, amps,… are all the same you can use it for CHARGING ONLY. There is a reason the adapter is 180w. This means that your laptop when being used can consume a lot of power and once you go past 90w you can easily damage the charger, laptop,… by doing that. So in other words find an original charger.
