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 20v charger on a 19.5 V laptop?
20v can be used for 19v as long as the current rating of 20v is the same or higher but only temporarily. Best to charge the battery and the then unplug and run the laptop, notebook etc on their batteries themselves to ensure the correct input to the circuitory. Runng 20v for 19v directly is not advisable.
Can I use a 24v charger on a 19.5 V 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.
Can I use 19.5 V charger for 18V?
Yes should be ok just,as you should try and keep to less than 5% difference if possible. Make sure the power output is equal to or greater than the 18V one.
Can I use 19.5 V 18.5 V laptop?
Yes it is ok to use 18.5v charger as this voltage is lesser than the rated voltage of your charger(19 V). Amperage (3.5A v/s 2.37A) is insignificant as the current is dependent on the load (i.e Laptop) and not on the source.
Can I use a 5V adapter to power a 4.5 V device?
They’re very stable on the output voltage and can kick out an amp or so. It’ll work fine.
What happens if I use the wrong voltage adapter?
Current too Low – If the adapter has the correct voltage, but the adapter’s rated current is lower than what the device input, then a few things might happen. 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.
Can I charge a 19V laptop with a 12V charger?
NO you cannot charge your 12V AGM battery directly with a 19V Laptop power supply. You need a battery charger. The laptop power supply IS NOT a battery charger, it is a fixed voltage SMPS power supply.
Can I use 65w charger instead of 30w?
Yes you can but, it will charge at the same speed at which it charges with your out of the box charger at 30w and it will not damage or degrade your battery. So, there is no point in getting a 65w charger.
Can I use a 65w charger instead of 45w HP?
Yes, that’s right. Wattage is a measurement of how much power a supply can provide. If your computer requires 45w, but your power supply can provide 65w, you will be fine.
Can you charge an 18V battery with a 20v charger?
Add versatility to your tool box with the 20V MAX* to 18V Battery Adapter Kit. This adapter allows you to use select DEWALT® 20V MAX* Lithium Ion slide pack batteries with DEWALT 18V power tools.
Can I use a 5V adapter to power a 3V device?
There is not such thing (or there should be no such thing) as a 3V USB anything… USB is 5V, and always will be. It is a standard that all devices must comply with. This means that you should not be able to find an AC adaptor to 3V with USB, If you do find it, don’t buy it.
How do you use a universal AC adapter?
Plug the adapter cord into the device then plug the AC power cord for the adapter into a standard 120V outlet. If the device does not function, unplug the AC power cord from the outlet immediately. Check to make sure the voltage and polarity settings being used are correct.
Can I use 6V instead of 5V?
You could convert the 6V adapter to 5V if you’re comfortable with electronic circuits. This can be accomplished by hooking up the output of the adapter to a simple 5V linear regulator, which will probably have a dropout of 200mA.
What happens if you use the wrong charger for 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 24v power supply on a 12V?
Yes, plugging a 12 volt device into a 24 volt supply could very well destroy the 12 volt device. I had a 12 volt VoIP adapter that I connected to a 12 volt battery and smoked it. I then ran voltage tests on the battery and discovered it had a voltage of about 13.8 volts because of the constantly connected charger.
