How do I know the wattage of my adapter? 

For the first, it’s as simple as looking at the charger itself. This may have the wattage printed on it (as with Apple chargers) but it might have output(s) quoted as volts and amps. For example, if it says the output is 5V at 3A, then it’s a 15W charger because Watts = Volts * Amps.

Can I use 65w charger instead of 150w? 

For charging it would be fine. It wont damage the system but if it needs say 90w then it will pull from the battery instead of the adapter.

Can I charge my laptop with 65 watt charger?

The laptop will only draw the current it needs while running. 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.Dec 20, 2019

Can I use a 130w adapter on a 90W 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 130w charger instead of 65W?

Since your laptop came with a 65-watt power supply, it’s safe to assume your laptop needs no more than 65 watts of power. That means: The 130-watt power supply will work just fine and will have plenty to spare. The 65-watt power supply will work because that’s what came with the laptop.

What happens if you use higher watt charger?

No. The power rating of a charger has no bearing on the life of the battery nor the consumption of power by the device. A higher wattage charger only means it can supply up to the specified amount of current, not that it will push that amount of current to the device.

Can I use 135W charger instead of 90W?

Yes… and it depends. More likely it will pose no problem. Yet, on heavy usage, the 90W charger might get hot if the computer drains the maximum all time. If possible, have a 135W+ adapter as soon as possible to ensure that your charger is fine.

Can a 45W charger for 65W laptop?

The answer is yes. You definitely can use a lower wattage charger for your laptop (you can even charge your laptop without a charger!), but this will directly impact the performance of your laptop itself.

Can I use 150w charger instead of 135w?

Assuming its otherwise compatible (connections and voltage primarily) yes. You can use an overampere adapter and therefore higher watt. Watts is simply volts times amps. Always stay with the same volts.

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

The 19.5V vs 19V will not matter (it is a small enough difference); as long as the current rating on the charger is at least as much as the current rating printed on the laptop it will be fine. The chargers are “generic”; the same model is used for various laptops even with the OEM chargers.

Can I use a 12V power supply on a 19V?

Home / Blog / Can I plug in a 12V power supply for my 19V laptop? No, you can’t. The original 19V power supply has an output range of 16 to 22V and does not charge at low power.

Can I use 12V adapter for 5V?

The device will very likely burn out. In addition, depending on what the device is and the capacity of the 12V supply, connecting a 12V supply to a device rated 5V max could lead to a hazard – fire, explosion, etc.

Can I use a 20V charger on a 19V laptop?

I doubt it. 20V is just 5% more than 19V, which technically is the far end of the +/-5% tolerance of input voltage. However, your laptop would only leech what it needs from the power brick.

What happens if I use the wrong voltage adapter?

The device could power on and draw more current from the adapter than it’s designed for. This could cause the adapter to overheat or fail. Or, the device may power on, but the adapter may not be able to keep up, causing the voltage to drop (see voltage too low above).

Can I use a 19.5 V charger on a 18.5 V laptop?

so, yes you can use.. It should work. is it worth the risk? your laptop’s charging/regulator circuit is obviously designed to expect 18.5V, not 19.5V.

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.

Can wrong power supply damage 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.
