There is nothing more frustrating than having a discharged laptop battery. Even more frustrating is when you are unable to find your charger and your laptop dies. Many people carry a spare laptop charger in their car and that is a good thing. However, if you pull out your 19.5volt laptop charger to charge your 19volt laptop, are you going to have any problems?
In this blog, I investigate if you can use a 19.5v laptop charger for your 19v laptop.
Yes, you can use a 19.5V laptop charger for a 19V laptop.
However, putting a 19.5V charger on a 19V gadget is not a problem because chargers do not output exactly the quantity indicated. There are a few voltage differences, therefore the 0.5V difference is insignificant.
Chargers that are faulty or damaged are rather prevalent. Anything might happen over time to leave your laptop charger unusable. However, if this occurs, you should not charge your iPhone with any other adaptor. You should acquire one with the correct voltage and wattage for your computer.
Should I Use A 19.5v Laptop Charger For a 19v Laptop?
The first possibility is that you are looking for a new power brick and see that the 19.5V charger is much less costly than the 19V charger.
When you’re in this circumstance, you should not choose the 19.5V charger based solely on the price difference. Even if it costs extra to obtain the appropriate one, namely 19V, you must still provide your machine with the correct voltage. In other terms, if a charger with the appropriate voltage is available, you must not waste time hunting for something else to test.
The other scenario is that you’re seeking a new charger but can’t locate one with the exact voltage your laptop requires. You don’t have a choice in this circumstance, and you’ll probably need some energy back into your gadget as soon as possible. The scenario is unique here. As a last option, you can use 19.5V chargers on 19V laptops.
You may blow a fuse in the power supply, causing it and other components of your laptop to fail. Because your laptop will charge at a slower pace than usual, although having a high voltage, the battery will be destroyed.
What happens if I use the improper laptop charger?
Using such a charger with an incorrect voltage rating may cause harm to your laptop. An unusually high voltage is usually to blame. However, using a charger with an excessively high current will not harm your laptop. Using a charger with an insufficient current rating may damage the power supply but not the laptop.
1. Matching the rest of the specifications
Aside from the voltage, there really are a few additional specifications that vary across laptop chargers. If you’re using a 19.5V charger with a 19V gadget, ensure the other specs on both of them are almost identical.
2. Warranty Nullification
To begin, it is critical to understand that using a charger that is just not specifically designed for your device may result in the warranty being voided. This might be an issue if your laptop is relatively new, but for computers that have outlived their useful lives and are running on fumes, this is unlikely to be an issue since
a) either the period of their warranty has ended or
b) you’ve already done anything to invalidate the warranty.
The first thing to keep an eye out for is the current. If the voltage required by the laptop and the voltage supplied by the charger vary, ensure that the currents are the same. If there is a slight variance, such as +/- 0.5 amps, this is also OK. Or, if there really is a significant difference, ensure that it is in favor of the charger, implying that the larger current should have been on the charger rather than the laptop.
The laptop merely draws power from the charger as needed. For example, the laptop demands 4 amps, and the charger has a maximum capacity of 3.5 amps, this might be a problem since the laptop will not be quenched.
However, if the laptop requires 4 amps and the charger has, say, an 8 amp capacity, this isn’t a problem because the extra capacity on the latter doesn’t affect the laptop in any way. It will take necessary current at the necessary moment.
4. Pin Size
You should also double-check and validate that pin and slot are identical. The emphasis is on ‘exactly,’ since while a larger pin can be jammed into a smaller hole, or a smaller pin can hang within a bigger slot, this type of improvised device should be avoided at all costs. It can hurt your computer and damage the charging port.
The second section of this essay addressed the ‘Should you…’ component of this subject. Let’s get to the ‘Can you…?’ section.
Here’s the deal. It all comes down to how long you’ve had your computer running. No one would advise purchasing except what is clearly required by the laptop for a brand-new gadget. People are less inclined to be as picky about something aged and wrinkled. However, this will not imply that you should begin handling your gadget carelessly after a few years of use.
According to one online site, there’s nothing wrong with using a 19.5V charger on a 19V gadget because most power bricks don’t put out the exact voltage they say, and most of them tell it a bit higher than it actually is.
One user states that when the 19V chargers were tested, they all showed a higher value. Some even outperformed chargers designed to provide 19.5V.
If the charger in issue meets the remainder of the requirements (as indicated above) with the laptop, we believe it should work OK. For newer gadgets, the warranty issue may be a bit of a problem. However, because the 0.5V discrepancy may already be present in your 19V charger, you should be alright utilizing a 19.5V charger with your laptop.
We may simply state that using a 19.5V charger for a 19V laptop is not harmful in any manner. Therefore, if someone has any qualms about doing it since the laptop is relatively new, then this is preferable from a cautious standpoint.
