How to Identify Original Laptop Charger

There are several ways to identify a genuine computer charger. One way is by checking the packaging and if it is sealed then you can be sure that the product is genuine. If the packaging has been opened, then one should check for a holographic sticker on the adapter or on the charging cable.

Another way to know if it’s original is by looking at the cord, a genuine laptop charger will have insulation covering for added protection and durability. Also quality of the plastic casing. If it feels flexible then this is a sign that it was cheaply made. It will not be able to withstand bends or heavy use, meaning its lifespan will be much shorter than expected and it is likely to break prematurely.

The weight of the charger is a good indicator for identifying if the charger is fake. The weight of a real charger should be around 0.8-1.2 pounds while the weight of a fake charger will be much lighter at about 0.4 pounds.
