You can check if a laptop’s charger is geniture or not by following some steps. Before that, you must know about the chargers available in the current market. Besides, you should also keep in mind some factors that an original adapter should have for supplying appropriate power to your battery.
1. Types of Laptop Chargers/Adapters
First thing first, we must say there is a range of options of charging adapters for the laptop computer on the market. We found TWO types out there. The genuine(Org/Zin) charger and OEM charger for your laptop. Now, let’s a little about them–
Genuine Charging Adapters
They mostly come with your brand laptop computers directly from the manufacturers. There is nothing to worry about the quality and performance if you’re using them properly. However, many importers of your country may claim to bring them genuinely from the brand, especially while getting another one after damage.
In addition, they’re a bit pricey too. This is why people tend to opt for the OEM laptop charger only because of the higher cost.
OEM Charging Adapters
OEM refers to the “original equipment manufacturers” that produce almost genuine charging adapter equipment and are marketed by the other manufacturers. You’ll also find them in many categories such as quality assurance(replacement adapter), poor quality line charger, charging-lot, and imitation charger. Let’s know about the first two ones–
A “Quality OEM adapter” is like you’re getting a mid-range genuine charger at a higher cost. Obviously, not as much high as compared to the brand ones. But, they guarantee performance according to genuine standards, specialization, and order production set by the laptop manufacturers.
On the contrary, the low-quality OEMs provide a piece of average charging equipment at a cheap price tag. You’ll see no difference between them at first glance until you observe the fine components and performance.
2. Detrimental Effects of Poor-Quality Adapters
There is no immediate harmful effect of using such laptop chargers. But you can find many difficulties in the charging process after a certain period. We’ve discussed the issues and effects and how they can impact an adapter, battery, and laptop.
The charging adapter can produce several issues including fire and explosion. Of course, this will happen if there is trouble with the electric current in the adapter. Another reason could be the transformer box department that can’t resist heat and stress during plugged-in.
Besides, they tend to be hot easily along with the vulnerable structure and electric leakage. And that may lead to a very dangerous accident.
The main consequences of a counterfeit adapter greatly impact the laptop battery you’re charging. This is to say, a poor-quality charger has no such guarantees, specifications, and accurate voltage output system. So, they reduce your battery capacity and overall performance more than before.
A poor charging adapter can also harm your laptop components that are directly and indirectly attached to the battery. So, only a high-quality OEM battery charger can help you from possible damage to that hardware.
3. How Can Identify A Genuine Laptop Adapter?

Normally, a genuine adapter comes at a relatively higher price since it has good quality components. You’ll also find the difference between an original charger and a fake after experiencing the performance, efficiency, and heat stress. So, when you’ll ask about the price of one in a computer accessories shop they may charge a relatively higher price.
Weight of Adapter
We all know that genuine laptop chargers are equipped with good quality components like a transformer and other circuit mechanisms. That’s why you’ll be a bit heavier as compared to the poor ones. On the other hand, the cheaper ones make you feel much lighter.
The genuine adapter will come with heavy-duty materials like good plastic quality, flexible looks, and firmness. Besides, an ideal charger has good parts, circuits, and fitness from a firm foundation.
The duplicate or fake chargers will have a relatively smaller or bigger size as compared to the quality chargers. Because the genuine ones offer fixed sizes according to their standards and models. So, compare the size before buying your new one.
Slot and Jack
A good adapter always features a very tight slot and power jack indication for the charging department. Besides, they add many special symbols and information that clones don’t have.
You need a good charging adapter to keep the run battery and the laptops continuously. But, you should check at least once before taking them home. We shared some tips on how you can test a laptop charger to ensure whether it working properly.
