Robert. I would not hesitate to use an adapter(transformer) with a higher ampere rating than the device rating. Lower will result in overheating the adapter, depending on how much, and may result in a lower output voltage. However, I would hesitate to use an adapter with a higher voltage rating. Some devices can tolerate + or - 10% voltage. Beyond that I'd be skeptical unless the device was expendable. The polarity of the plug and receptacle must match, as often devices are not protected against reverse polarity. Do not use an ac adapter on a dc device or visa versa.
