Laptop adapter replacement supplier right now? Before we delve into the main categories of replacements offered by sellers online (including ourselves!), lets run through the key steps of finding what charger you need. How to find a compatible replacement laptop adapter? To see what kind of replacements are on offer online for your laptop, you’ll need some extra information on the model of the machine. Laptop manufacturers use all kinds of connections for charging laptops, and each vary in terms of wattage. The easiest way to find your laptop model number is by taking a look at the sticker usually placed on the underside of your laptop. Among information such as serial number, warranty, towards the top of the label should be the full model number or identifier.

Watts is calculated by multiplying the Volts by the Amps. Therefore a 19V charger with an Amps rating of 3.42A would be a 65W charger 19V x 3.42A = 65W. The higher the Amps the higher the Watts, provided the Voltage remains constant. It’s a Maximum Rating. The Amps and Watts rating on a laptop charger is a maximum output rating. This means that the charger is capable of outputting up to the maximum Watts rating. ie it can push up to x Amps of water through the pipe at a force of up to x Watts at the pressure (Volts) provided by the charger. However, to avoid any damage to your laptop it’s usually a good idea to check the polarity against that of the laptop or your original charger.
Once you’ve found a charger that provides the correct amount of power, the next step is to determine your polarity. For barrel-style plugs, you’ll see a symbol with a “+” and “-“ sign, connected to a ring and a dot. The symbol connected to the outer ring represents the polarity of the outside of the barrel. Similarly, the sign connected to the dot represents the polarity of the inside of the barrel. Most devices use an adapter with the positive connector on the center, but there are exceptions.
There are no guarantees on quality. Many of the universal chargers we looked at on eBay and Amazon came with no mention at all on warranty either. By nature of a universal charger, many of its parts are removable (such as the pin section). These can be wobbly or poorly fitting and will degrade over time. Finally, many universal laptop chargers have a switch to manually select the required voltage. Plugging the charger into your laptop with the wrong voltage selected can cause irreversible damage to your laptop. In summary for universal laptop power adaptors, we can’t recommend them as there are too many factors that can risk causing damage to your laptop.
