Do you remember how often we used to hear about hover boards catching fire and causing lots of damage? The popularity of the devices led to a rush of off-shore companies to get anything they could to market without much regard for testing or safety. Improper charging systems with the wrong amperage connected to Lithium-Ion batteries is the most likely reason that we saw so many catching fire. While most of us don't have a need for a hover board, the issue that caused their problems can happen to anything you own that has a lithium ion battery. We've seen lots of customers that ended up damaging their laptops, for instance, because they chose to use a cheap non-factory charger. The damage can range from overheating to catching fire and it's almost a guarantee to shorten the life of the battery. Keep in mind, heat is an indicator of a battery problem, so if you notice that yours is getting very hot during the charging process, make sure you have everything checked out to avoid damaging your laptop.
