Een AC adapter voor Dell

Power adapters, also called an “AC adapter” or “charger”, plug into a wall outlet and convert AC power into a single DC voltage. Computers use multiple DC voltages, and the power adapter is an external part of a Dell laptop's power supply. In Ac Adapter for Dell, DC voltages are created by internal circuitry.

How to choose an AC adapter for Dell?

Dell's charging takes place in a single internal unit that converts AC power to all DC voltages. You can purchase a compatible power supply for your laptop from the specialized online store “Dell Parts”. Let's start with the simplest: tension. The output voltage of the charger or power supply should be as close as possible to the needs of your computer or device. It is necessary to choose the correct voltage. Some devices are quite tolerant of voltage drops and will work. There aren't many others. The device can operate at similar voltages, but this is often at the expense of its service life. If the voltage drops significantly, it can damage your device.
Since there's no easy way to know which category your device falls into, make sure you get the thrills right from the start. Many are confused by the current rating and its value. The rated current is the maximum power it can deliver. This device uses exactly as much power as it needs to do what it does.
If you look closely at the Ac Adapter for Dell, you will see that they are designed to plug into any input between 100 and 250 volts. What they can do is take almost any input and create fixed, stable outputs – looks like an electrical engineer to me.

In short, take care of the following things:

Make sure the voltage matches.
The new power supply is suitable for the same or higher current.
Make sure the connectors match physical shape and polarity.
Especially when it comes to the popular round AC adapter for Dell , make sure the expectations are the same: if the device expects the center connector to be positive and the outer ring negative, your power supply's connector should match. There is no escaping it. If you don't, it won't work at best and you'll damage the device at worst. Keep a close eye on the lights on both the power supply and the device you connect it to.
