I bought a cheap replacement charger for my laptop because I kinked up the old one and broke a wire. Stripped it down and soldered it but thought I would get an extra just for the heck of it. All specs are the same except the input amperage is 2.3. My old one was 1.5A. It works but I was just curious if there will be any problems down the road with the amp difference or if I should be OK since its rated higher. TiA.
