Do you want to buy a new laptop charger/adapter because your old one is defective? Would you like an extra charger for your workplace? We have tested and listed a wide range of laptop chargers. When ordering, make sure that the voltage of the new one corresponds to that of your old type. The power or maximum current that your new charger can deliver must be equal to or greater than the old version.
Best Laptop Chargers:
Choose a new laptop Charger/Adapter
A laptop charger/adapter is an AC / DC power supply that converts the AC voltage from the mains into a DC voltage with a low and safe voltage that is suitable for powering your computer and charging the built-in battery. If you want to order a new one to replace a lost item or you want an extra charger for travel or office, it is important that you order the correct type. Unfortunately, a laptop adapter is not standardized as with smartphones.
That is why there are many different types in circulation, each with their own electrical specifications and connection. It is therefore important that you choose a laptop adapter with the correct output voltage and sufficient output power. If you choose one with too low a voltage, the device will not operate and the battery in your computer will not be charged. If you choose one with an output voltage that is too high, it can damage your laptop, causing an expensive repair. If the laptop adapter has insufficient power, it can be overloaded by the computer, become too hot and switch itself off.
The universal laptop Charger
The universal adapter comes with various power plugs. By choosing the right power plug, the universal version is suitable for almost any computer brand. When selecting a universal adapter, it is important that it can be connected to your equipment. Unfortunately, on some types of laptop adapter the power is not indicated, but only the voltage and current that the product can supply. In these situations you must calculate the power yourself. You can do this simply by multiplying the DC voltage by the maximum DC current that the product can supply.
The correct supply voltage
Once you know how much power you need, you can choose an adapter that can deliver the required power. A laptop regulates how much power is required from an adapter. If you have found one that can deliver the correct power, it is important that you check whether the adapter can also supply the correct voltage. The required voltage is on your old charger or on your laptop. Please note, the voltage must match within half a volt of the voltage your laptop requires.
If the voltage is too low, your laptop will not function properly and if the voltage is too high, your laptop can be damaged. An exception are the Apple laptop adapters. These are equipped with a Magsafe or the thinner Magsafe 2 magnetic plug and indicate to the laptop how much power they can deliver, the laptop adapts its energy demand to this. All the laptop chargers operate on a mains voltage of 110-230 volts and a mains frequency of 50-60 Hz. You can use the laptop adapter worldwide. All you need is a power plug when traveling outside of Europe.
