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' and 'Netzteil' can both refer to a technical part that supplies a device with electric power. In this sense, the words are close in meaning. However, 'Netzteil' is the normal, concrete word for the device or adapter, for example with a laptop or router. 'Stromversorgung' sounds more general and technical; it can also refer to the function or the whole power supply of a device. Learners may confuse the words because both occur in electronics. In everyday language, people usually say 'Netzteil' when they mean the individual device they can hold in their hand.
In der Werkstatt liegt ein neues Netzteil für den kaputten Laptop.
There is a new power supply in the workshop for the broken laptop.
Bei diesem alten Computer ist die Stromversorgung defekt und muss ausgetauscht werden.
In this old computer, the power supply is defective and has to be replaced.
