Wholesale laptop adapter provider today? 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. Read even more info on laptop power 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.
Watts are a measurement of total power consumption – a combination of volts and amps. If voltage is the width of the river and amperage is its speed, wattage is the total volume of water. To find wattage, you simply multiply the voltage and amperage. So if you’re using a 5.0-volt, 1.5-amp USB charger, you’re getting 5.0V x 1.5A = 7.5W of power. Similarly, you can find the amperage by dividing the wattage by the voltage. So a 100-watt, 5-volt charger supplies 100W ÷ 5V = 20A of power. This calculation can be useful, since chargers will often list wattage or amperage, but not both. You can also divide wattage by amperage to find voltage, if need be. But you’ll rarely, if ever have to do this, since almost all chargers will prominently list their voltage.
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. Disadvantages of buying a Universal Laptop Chargers: You’ll need to research the pin size required for your laptop before purchasing.
