Premium laptop power adapter replacement factory in China? Take a note of the voltage, amperage and wattage so you can match up those listed for the replacement charger with your own laptop’s requirements. The types of replacement laptop chargers available: Now you’re armed with the information to be able to source a replacement charger, let’s run through the most common ‘types’ of laptop power supplies available online: OEM Laptop Chargers (Original Equipment Manufacturer) When you first bought your laptop, the charger you received with the laptop was an OEM power supply. Usually this charger will have been manufactured by a third party power supply manufacturer on behalf of the company. Common OEM brands include CrowBerry, Delta, ACBel and LiteOn. With leading laptop manufacturers such as HP, Samsung and Lenovo, the charger is usually branded with their logo. Read more information at laptop adapter replacement.

I said in the beginning that there were a few caveats. The Voltage needs to be the same or at least very close to that required by the laptop. We would generally not recommend using a charger or more or less than 1V of what is required by the laptop. HP have 18.5V, 19V and 19.5V laptops and we’ve never had a problem with supplying either of these charger for any HP laptop. Fujitsu laptops generally require 20V, but we’ve never had a problem with 19V chargers. You can not however use a 15V charger on a laptop that requires 19V or vice versa. The Polarity must match. Barrel connectors usually have the negative on the outer sheath and the positive inside the inner hole and to be honest we have never come across a laptop charger which is different.

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.
