Laptop power adapter replacement manufacturer with laptoprepair.com? 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. See additional info on laptop adapter replacement.
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.
Regardless, it’s essential to get the right polarity! A charger with the wrong polarity can cause your laptop to overheat. If your laptop is equipped with a polarity fuse, the fuse will blow. You’ll need to replace the fuse, and you’ll still need a new charger. If your laptop doesn’t have a polarity fuse, you’ll potentially cook your entire machine. Compared to everything else we’ve discussed, plug measurements are relatively straightforward. There are two measurements: one for the inside diameter, and the other for the outside. Both are measured in millimeters. This is generally noted as “5mm OD x 2mm ID” or something similar. If need be, you can also check by simply plugging it in. Provided the polarity and power supply are correct, connecting the wrong size adapter won’t do any harm. It just won’t work.
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.
