Never heard of a chromChrom model? What is the full ACER model name and number on the laptop label?  Sounds like the charger's plug wasn't pushed straight into the laptop's port and bent the center pin inside the laptop. Does the laptop still turn on? Jack E/NJ  

As Jack said, it could be the charging port is damaged, but it could also be a failed charger as you suggest. You can visually inspect the port to see if the center wire is still there and straight. You can try the charger without the tablet connected to see if the charger alone is enough to trip the breaker. If it does, replace the charger and you should be good (unless the surge fried the tablet, in which case all bets are off). If the charger doesn't trip the breaker by itself and the charge port looks good it's liable to be a short in the cable, which again means replace the charger. I think the problem is likely in the charger itself, since a dead short in the cable or in the port is more likely to fry the charger than to trip a breaker. Remember the charger normally only pulls a few watts of power (often 45 watts for a Chromebook), and a typical household breaker doesn't trip until the overload passes 1800 watts (120V * 15A).
