Correct. Take a look at the power plug/adapter/brick and look for the wattage. If it's 65w or less you'll be OK but anything greater runs the risk of not charging as the a/c may not be equipped to handle it (there is a thread about this out here somewhere but it's 3am and I'm flunking trying to find it
)
