No. The windings are set for 9vdc and will not step down to 5vdc.
What else can I help you with?
Can a 9v charger be used in a 12 v battery?
No.
Can a 9 volt battery charger be used to charge a mobile phone?
Most of the mobile phones have batteries of less than 5V rating, mostly up to 3.7V.Chargers are typically rated for less than 5V.Caution: It is not safe to charge these with a 9V charger. The battery may explode..
How many watts does a 5V 2A charger output?
A 5V 2A charger outputs 10 watts of power.
What is the power output, in watts, of a 5V/2A charger?
The power output of a 5V/2A charger is 10 watts.
Can 5v 1amp charger charge a 5v 2amp battery?
yes
What is need of signal conditioning?
To modify the input voltage to match the desired output voltage. Say you need 5V to operate TTL technology and you only have a 9V battery. You build an SCC change it from 9V to 5V.

Can you use an AC adaptor with 9v output and plug it into a device that has 5v input?
No the voltage gap is too wide. If the higher voltage is used there is the possibility that the connected device might be destroyed.
Can you use a 5v 1A charger for a 5v 500mA device?
No. In general, a charger needs to be able to figure out when the battery has reached full charge, otherwise the charger can damage the battery by overcharging it. You need to use the specific charger required for the battery. And, if you are trying to power a non-battery device that requires 1A from a 5V 100mA source, you will not be able to maintain 5V, so it will not work there either.
Can a dc 5v device use a dc 9v cord?
That's almost twice the voltage. The chances of frying your device is high.
Would a device requiring dc 9V 1000mA output work with an adapter with dc 5V 3A in output?
No. Usually it's a -/+ 10% difference. So, a 9v would need at least 7.2 volts or more
What is the current if a 9v battery is put through a 5v regulator?
It depends on the load. If there is no load, it will only draw the regulator's quiescent current, specified on the datasheet.
