Review on High-Quality 45W Laptop Power Adapter Charger for Hp Stream 11 13 14, Elitebook Folio 1040 G1, Spectre X360, and more! by Mike Bogan

This charger meets the size, voltage and current requirements for my HP 14 inch laptop. However, I've found that when plugged in, the touchpad jumps wildly with every touch. Investigating seems to have come down to the fact that the charger isn't grounded. I have tested 3 other HP chargers from other laptops in our house, all of which are 3 pin grounded power supplies. None of the others caused this problem.
