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.

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.

Do I need a 60w or 85w charger?

You can charge using a higher wattage than is permitted, but you should not use a lower wattage. 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).

Can I use a higher wattage Adaptor for my laptop?

The short answer is yes you can use a laptop charger with a higher wattage, however, there are some caveats. The wattage rating of a laptop charger is a maximum rating which means that the charger is capable of providing power up to the output wattage rating and or course anything in between.

How do I know what charger to buy for my laptop?

Find your laptop’s model number. You may find this number located on a sticker on the bottom or side of your laptop computer. If you can’t find it there, check your user manual or search your laptop’s built-in help program for the model number. You can also find it under your laptop’s system properties.

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 45w charger instead of 60w?

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.

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.

Can I use 90w charger on 65w 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.

Can I use a 45w charger instead of a 65w charger for my HP laptop?

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.

Can I use a 19v charger on a 15v laptop?

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 we use 65w charger for 45w laptop?

It takes 200 cells at 1.5 volts each to produce 300 volts.

Can you use 19v charger 18.5 V laptop?

Yes you can use the 90W adapter without any problems on the computer since the difference in Voltage is minimal and in the accepted range.
