What would happen if I applied 7.5 VDC but with higher current?
What about higher voltage but 1 A?

You need to supply the device with a power-supply that gives 7.5 volts, but has a current rating above the 1 amp requirement. The device will not "force" more current into the device.
If you use a power-supply with a higher voltage, you may damage the device. If the device draws 1 amp and you use a power-supply that can only supply 1A or less, you may damage the power-supply.
Conclusion: use a power-supply (or battery) that matches the voltage, but is capable of supplying more current than needed.

Depending on your device it probably has an internal voltage regulator of sorts so that you could apply something in the range of 7 to 8 volts without any problem. Your power supply needs to have a rating of 1 A or above. A higher rating will not damage your device.

You need to supply the design voltage with a device that is rated to be able to supply that voltage with at least 1 amp current, so if you had higher current available, it would be ok. Don't hook up to a higher voltage, it could fry something.

More current is always better - in a Tim Allen sort of way.
