Probably not.
There are two types of adapters- regulated and non-regulated. An unregulated 9V adapter might have as much as 16 volts across its terminals when not connected, and deliver only 9V under load. Enough to fry something expecting 7.5 volts.
A regulated 9V adapter is better behaved and will probably deliver 9-10 volts. Still, this may well fry your 7.5 V device.
Get the right adapter.

Can you use adapter with output 5v 3amp to operate adevice with 5v 1amp?
Absolutely. The first rule: Source voltage should be equal to the device voltage. The second rule: Source current sould be higher than the cumulative of the device's current.
Is it ok to use a 5V 2a adapter on device that requires 4.5V DC 700 mA?
No
Will a 6v 2.2a adapter damage a device that requires a 5v 2.5a adapter?
Yes it will
Can you run a 4.3v device with a 5v power adapter?
Yes, you can run a 4.3v device with a 5v power adapter as long as the amperage of the 4.3 volt device is under the amperage capacity of the 5 volt adapter.
Can you use a 12V DC adapter for 5V DC device?
input voltage is strictly according to applications. If use 12V dc adapter power 5V dc device, the 5v dc device would be damaged.
Can 5V 2A works with a device requiring 5V 2.5A?
No... the source does not have the required capacity. The device (sink) would ask for more current which the source will not be able to provide. Do not use this source-sink pair.
How can you convert plus 5v to 5v?
By changing the polarity of the source
How you can convert plus 5v to -5v?
By changing the polarity of the source
Does anyone know what kind of adapter an image 9.5 elliptical machine uses?
erm i think its the beryl 3.5 edition version 2.3 adapter.---------------5v 1amp, I use a Zip drive adapter I got from ebayMike
Is it safe to use a 5v 1200ma router power adapter instead 9v 600ma adapter the original one for a longer period because everything works fine for now?
no .never
Is it ok to use a 4.5V or 6V from a universal ac adapter 1300ma for device that requires 5V dc?
yes, depends on equipment..
Can you use 5v ac adapter instead of 4.5v ac adapter?
Yes the voltage is close enough to work. What you have to be cautious about is the milliamp output of the adapter. Make sure that the output of the adapter is higher than the device that plugs into it.
