Laptop power adapter replacement provider in China? 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. See even more details at https://www.laptoprepair.com/product-adapter.html.

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 a Universal Laptop Charger: They are usually affordable; If you have multiple laptops that the universal charger is compatible with, you can use the charger on each laptop.
