Premium laptop adapter replacement supplier by LaptopRepair? It’s always important to look for the main model number rather than the ‘range’ listed around the keyboard as this isn’t always enough detail to find the right charger for your device. If you can’t locate the sticker or it’s difficult to read, you could take a look at the original invoice/receipt or check the manual that came with your laptop. If the laptop hasn’t discharged completely, you can also find the model number on the powered on machine. Discover even more information at https://www.laptoprepair.com/product-adapter.html.
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.
Unlike voltage, amperage does not be exactly matched to your device. You can use a higher amperage charger with a lower-amperage laptop, but not vice-versa. So a 4.5-amp charger will work with a 3.25-amp device, but a 3.25-amp charger won’t power a 4.5-amp device. Keep in mind that it’s sometimes possible to use a lower-amperage charger if the numbers are close enough. However, this is a Very Bad Idea. In the best case scenario, over-power circuitry in the charger will deactivate it. In the worst case, the charger can overheat, permanently burning out the circuitry or even starting a fire.
Advantages of buying an OEM laptop charger: It’s exactly the same in function to your original charger, so you can expect the same performance; Providing you buy the correct charger, it’s guaranteed to work with your laptop. OEM chargers can be difficult to source, particularly for older models of laptop; the OEM manufacturer may no longer produce the charger for your laptop. They can be expensive, depending on availability. There are an abundance of fake or counterfeit OEM chargers sold by private sellers across marketplaces such as eBay and Amazon which are potentially dangerous. These can be incredibly difficult to identify, even when comparing the original with the counterfeit in person. Fake chargers often lack various features that make chargers safe, such as temperature control and short circuit protections.
