Basically, all that is is a large battery. The problem with any "one size fits all" unit is that they really don't fit all. Unless you are comfortable that you can pick the correct adapters from the set they send you and set the voltage correctly, I think you would be much better off to buy a second battery from MSI for your laptop.
