I wanted to use an old electric driller that it's battery has worn down and i couldn't find a new battery. on the battery it says 7.2V. So i took a AC-> 7.5V DC 1A Transformer and used it in place of the battery. it worked, but it didn't had a lot of power, and I'm trying to figure out way.
can it be that the driller need more then 1A? it doesn't make sense cause in this current it probably drained the battery in a few consecutive minutes.
