Quick question on 12v power supply

I have electrostatic speakers that use a wall wart power supply . The wires have come loose over time from coming in and out of my rig over the years . I am looking to buy new ones and have ordered a pair of 12v from Audio Advisor . They are the ifi model shown here
https://www.audioadvisor.com/prodinfo.asp?number=IFIPOWER&variation=12V

Looking at all the 12v available for sale ,I do not see what is written on the Kings supplies (12v 250ma) . Is this 250ma number of importance ?

Thanks,mike.

The 250ma refers to 250 milliamps which equals 0.25 amps.

It refers to the current capability of the power supply. Anything below this value won't be able to maintain 12V.

Usually overrating the power supply is safe, so if you find anything in the 0.3 to 1 A it will be fine.

Best,
