Most of our everyday electrical devices are powered by a so-called AC/DC power supply. You find it on your radio, on your rechargeable LED lamp or on your Hifi system. And the same goes for your laptops. It will certainly happen that your device stops working. The problem is probably due to the power supply and you should change it. How ? There is nothing simpler and we explain it to you here.
Understand the information on the original power supply
Each power supply has information that must be provided by the manufacturer. It is the same for an adapter for panasonic laptop. The model of your power adapter is noted on the label. Just identify the input voltage input and the output voltage output that you must respect. For example, for a 120V AC 60Hz input, this corresponds to the current of an English socket.
In your case, you would rather need a 220V power supply which corresponds to the European household current available in the walls. You will also find an output voltage on the power supply. It is imperative to respect the original imposed by the device and a higher or equal intensity for the device to work correctly. If you have a 350mA supply, your device needs at least 350mA. With a 600mA power supply, it works. With a 300mAh power supply, it does not work.
Locate the connector
The last, and not the least, element to take into account is the type of connector. All universal power supplies allow the polarity to be set in one direction or the other. So it's actually very simple. At home, be careful about the electrical diagram to reproduce to allow the proper functioning of your device. It's about how to position the male end on the female plug. This by having previously selected the necessary tension thanks to the adjustment key allowing to position the rotary switch. You should follow the same pattern as on the old PSU. This determines how you will need to position your connector before commissioning.
