Quick Answer: Can I Use A 19v Charger On A 19.5 V Laptop?

What happens if you use the wrong laptop charger?

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 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.

Can a 15v adapter 12v device?

Not very familiar with electronics. the 15v (i guess its dc) will power a 12v ozone device. I read that things need to have the same polarity, same v, but varies MA is fine. The voltage should match and as long as the power supply has at least the amperage required by the device you should be fine.

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

Your laptop takes 18.5V and the new charger is 19.5V. That is just a just a hair under 5% difference (18.5 + 5% = 19.425). Generally speaking, a 5% variance in voltage up or down is acceptable when in computer power supplies. … As for amps, the computer will only draw as many amps as needed.

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.

Can a bad charger ruin a laptop?

However many laptop manufacturers manufacture laptops that can use multiple different chargers, and vice versa. Just make sure the output supply voltage is almost the same, and the output current either greater than or equal to the original. Even a poor quality adapter is very unlikely to spoil the laptop.

How do you reduce voltage from 19v to 12v?

The simplest way is a 12 v battery and a resistor from its positive terminal to the 19 v positive supply. Connect the load accross the battery. And the other terminal of the 19 v to the other terminal of the battery… .

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.

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.

Is it OK to charge phone with higher amp?

Yes, a phone charger with higher amps will charge your mobile phone much quicker, but only if your mobile supports fast-charge technology or has a compatible fast-charge circuit. If this hardware is not present in your mobile phone then it will get charged at the normal pace.

Can I use a 6v adapter to power a 5v device?

If you’re mildly comfortable with electronic circuits, you could convert the 6V adapter to 5V. This can be done by hooking up the output of the adapter to a simple 5V linear regulator (the 7805) — the dropout would probably be low enough at 200mA to supply 5V.

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.

Can I use a laptop charger with higher voltage?

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 I use a 19v adapter for 12v?

19V is generally going to fry any device that was designed to run at 12V (especially consumer products). And while it’s not very likely it might also catch fire. For a AC adapter to work you will need one with the exact voltage (12V) and an equal or higher current rating (1.5A or more).

What happens if amperage is too high?

A higher voltage than a device is designed for will most likely blow up some components, but amperage is derived from how much current is actually drawn, based on the device’s resistance, so having “too much” is not a problem and will do no harm.

Can I use a 2a charger for a 1a device?

If you plug a 2A device into a 1A charger, you will only get 1A. The device will charge more slowly (1/2 speed roughly) but everything will be fine.

Does higher amps mean more power?

So amps measures or indicates the maximum time a tool can continuously run without exceeding the temperature limits. Amps basically measure how effectively the motor cools itself, not how much power it has. With this in mind, more amps can be good because motors will run longer and won’t heat up as fast.

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 90 watt charger on a 120 watt laptop?

You should not use a 90 Watt brick if you need a 120 Watt brick. While I talked about charging currents, The max output requirement is based on Charging current required by a depleted battery pak + Operating current required by the laptop under full load.

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

“if you use a 20v charger on a 19v rated thing, you will be “forcing” an extra 0.235A (V=IZ, Z is the appliance’s impedance) into the device in addition to the 4.47A.” This does not make sense.
