Can I use 20v adapter on 19V laptop?
Originally Answered: Will 20V 2A charger damage my laptop, which has 19V 3.42A rating? Yes, that one will over volt your motherboard and battery charging circuit. You need a 19 volt charger with the right connector.
Can I use 18V adapter for 19V?
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 12V adapter for 19V?
A 12V adapter is unlikely to damage the components, but it is possible depending on the design and that’s why I mentioned it. The likelihood is probably vey tiny though so you can probably ignore that bit.
Are most HP laptop chargers the same?
HP laptops do not have one single compatible laptop charger. Before attempting to purchase a compatible replacement laptop charger for your HP, it is worth checking with the manufacturer for compatibility with your PC.
Can I use a 19V charger on a 19.5 V laptop?
It’ll be fine. Laptops have internal high-precision voltage regulators which convert down from the very roughly-regulated voltage supplied by the charger to the exact voltages they need for different things so half a volt won’t make any difference.
Can you use a 12V adapter for a 15V device?
Onus : Assuming the polarity is correct, plugging in a 12V input to a device requiring 15V won’t do any damage, however if you undervolt an amplifier, you may get clipping or other distortion.
What happens if I use the wrong voltage adapter?
Some laptops and other devices include polarity protection, which is essentially a fuse that burns out if you use the wrong polarity. If this happens, you might hear a pop and see smoke. But the device may still work on battery power. However, your DC input will be toast.
Can I use a 18.5 V charger on a 19V 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.
What happens if you plug a 12V into a 19V?
19V in general is too high for a 12V device. I wouldn’t recommend going any higher than 14–15V. Even if your device works for some time, it will likely get damaged after some time (it could be seconds, minutes, hours, days…).
Do all HP Chargers work for all HP laptops?
