Frequently asked questions about AC adapters
- How do I find the right power supply for my Notebook in your online shop
In our online shop you can choose your notebook in the menu on the left, then all compatible articles will be listed.
If you can't find your model, you can also enter the manufacturer part number of your power supply in the search.
Examples for manufacturer part numbers:
Toshiba: A000007000, K000060890, PA3468E-1AC3
Acer: AP.06501.024, 7452480100
Fujitsu-Siemens: UWL:76-01B900-5A, WTS:25.10173.071, FSP:811002431

ADP-60SH B, PA-1650-54, ADP-90CD, PA3468-1AC3
- My laptop battery is no longer charging, is my charger broken?
Not necessarily, try taking your battery out (if possible) and starting the computer while connected to the charger in question. If it starts, the power supply is working but something in the Notebook is broken.
There are also multiple indicator lights, on the laptop, whether it is being charged, also this can be seen in most operating systems. You can also use the indicator light found on some chargers to diagnose an issue with a cable.
- My USB-C charger will not charge my device correctly
Oftentimes the reason for this is, that with USB-C all devices have to agree on the current and voltage used for charging. Therefore, all involved devices must support USB Power Delivery, so that enough power can be transmitted to charge devices such as laptops. The cable used for charging is also part of these devices, which means you have to make sure your cable supports USB-PD. If one or more devices do not support USB-PD a maximum of 15 Watt can flow.
- Why is my power supply humming, hissing or beeping
Basically, a power supply converts the AC voltage from the mains into a lower DC voltage for a consumer. In the case of a laptop power supply, the output voltage and maximum output current are usually fixed.
The main component of any power supply unit or power supply is a transformer. In laptop power supplies, this is usually characterized by a very compact design.
The 220-volt alternating current from the wall socket generates a magnetic field in the transformer, whose charge changes from positive to negative 50 times per second. These electrical oscillations can cause parts of the transformer wires, iron cores and coils to move slightly. While the parts are usually glued together tightly, the connections can become partially loose for a variety of reasons, or the insulation on the coil wires can become brittle. And this can cause the annoying noises. The power supply hums.
The movements of the transformer components can also be transferred to other components in the very compactly designed laptop power supply and cause additional small vibrations there, which also cause noises.
Reassuring when the power supply hums: Noise developments in power supplies don't affect the electrical functionality and are usually harmless.
Depending on the cause of the noise, mounting the power supply differently, e.g. on a different base or on a piece of foam rubber, may solve the problem.
- Will my battery charge faster with a power supply that has a higher wattage
No, because a circuit in the Notebook controls how much power arrives at the battery and not the charger.
