I have an external DVD drive that needs a replacement power adapter. The label says it needs 12V 2.0A, but the manual says:
12V 2.0A (max 2.5A)
What does that max 2.5 Amps mean?
Will the device possibly draw 2.5 amps, or am I limited (for some reason) to using a power adapter that won't provide more than 2.5 amps?

Means peak consumption is 2.5A. On the power supply side, the more amps the better, as long as the voltage is the same.
it means that if your power adapter is above 2.5A, the voltage must be at least 18Vdc.

I'll use a 2.5A adapter, but why why the specs even bother list 2.0A if the device might draw 2.5A?

Are you from Canada?

Spikes in power consumption can happen, also a good 2A power supply can easily supply 2.5A for a short time if needed
>>62045420
Get an adapter that can supply greater than or equal to 2A. The load only draws as much current as it needs. Getting a 12V 5A adapter for instance doesn't mean it'll push 5A through everything it's connected to, it just means it can supply 5A max. If an adapter pushed it's maximum rated current through any load it'd mean you could kill people with a phone charger.
Going lower than the rated current won't be harmful to the device but if your device needs 2A to function it might not work correctly if it's only getting 1.5A. Maybe the motor spinning the DVD runs slower, the laser intensity is lower or it fails to power on entirely, shit like that.

Thanks. I found an ebay ad of my model and took screenshots of the drive and the power adapter. (contrast to the OP pic from the manual)
I'll surmise that a 2.0A supply will do, but 2.5A is even better?
>>62045631
No. They will perform identically.

The manual, page 4 shows the 2.5 max in the specifications.
