Quick question on 12v power supply

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,

@eriksquires  Thanks for that info . Looks like the ifi is 1.8 for the 12v I am getting 

Perfect.

"Perfect"

Hmmm, 1.8 is much greater than 1 limit?? Just saying. 

As a a reference, I tried that ifi charger (came with ifi reclocker) on a small cordless screwdriver rated at 12v and 0.3amp and it got real warm real quick. Maybe OK but I didn't leave it connected for too long.
