power supply
A device that supplies an electronic device with the correct voltage and current from the power grid by converting the mains voltage.
Ich glaube, das Netzteil meines Laptops ist kaputt, weil der Akku nicht mehr lädt.
I think my laptop's power supply is broken because the battery no longer charges.
The word is made up of 'Netz' (here in the sense of 'Stromnetz' (power grid)) and 'Teil' (part). So it is literally a part that establishes the connection to the power grid.
Ohne das richtige Netzteil kannst du das Gerät nicht aufladen.
Without the right power supply, you can't charge the device.
'Netzteil' (power supply) is often connected with the device it belongs to, e.g. 'das Netzteil vom Laptop' (the laptop power supply) or 'das Handy-Netzteil' (the phone charger). Typical verbs are 'anschließen' (to connect), 'einstecken' (to plug in), or 'ist kaputt' (is broken).
Ich habe mein Netzteil im Hotel vergessen.
I forgot my power supply at the hotel.
Although it is a technical term, 'Netzteil' (power supply) is used very frequently in everyday language because almost everyone owns electronic devices.
Kann ich mir kurz dein Netzteil leihen? Mein Akku ist leer.
Can I borrow your power supply for a moment? My battery is dead.

Stromversorgung can generally refer to supplying a device with electricity, but it can also refer to the device used for this purpose. Netzteil always means the specific component that converts and passes on the electricity in the appropriate form. Use Stromversorgung when the function is the focus, and Netzteil when you mean the device.

Die Stromversorgung des Routers funktioniert wieder, deshalb leuchtet die Anzeige.
