FRITZ!Box 7590 Service - Knowledge Base
Suitable power adapters for the FRITZ!Box
Only use a power adapter supplied by AVM that provides the power required by the FRITZ!Box. You can find the corresponding information on the sticker on the underside of your FRITZ!Box (see fig.) and on the underside of the respective power adapter. The FRITZ!Box may malfunction if you use an unsuitable power adapter.
Fig.: Power specifications for the adapter
Note that the voltage (V) given on the FRITZ!Box and the power adapter must be identical. The amperage (A), on the other hand, is a minimum value; that means that the power adapter must provide at least the amperage required by the FRITZ!Box. If the ampere rating on the power adapter is higher than that required by the FRITZ!Box, this is not a problem. In this case, the power adapter is not used to full capacity.
FRITZ!Box 7590 requires 12V/2.5A and cannot be used with a 12V/2.0A power adapter.
FRITZ!Box 7560 requires 12V/2.0A and can be used with a 12V/2.5A power adapter.
FRITZ!Box 7312 requires 5V/1.6A and may not be used with a 12V/2.0A power adapter under any circumstances.
