I'm wondering if it's safe to power my 12V 0.75A keyboard with a 12V 1A adapter. I know that generally using an adapter with a higher amperage is fine, but I'm a bit worried that the extra amperage could damage the keyboard or cause issues. Can someone clarify if this is a concern or not?

The concern usually arises with voltage, not amperage. Devices will only pull what they need, but if the voltage is higher than rated, that can cause problems. Hypothetically, if you used a 12V 100A adapter, your 0.75A keyboard would be fine as long as the voltage is correct!
Yes, you can totally use that adapter! It's common to use a power adapter with a higher amperage than what the device requires. Just make sure the voltage matches.
Don't worry! The device will only draw the amperage it needs, so using a 12V 1A adapter for your 0.75A keyboard is perfectly safe. The extra amperage won't blow anything up, that's just not how electricity works.
Thanks for confirming that!
