Are two prong plugs grounded?
Two-prong outlets have no ground wire, without which the risk of electrocution and appliance damage is substantial. Simply adding an outlet with an additional prong will give you added appliance access, but it will not give you the safety that grounding provides.
Does a surge protector need a ground?
Yes, surge protectors can be connected without grounding. Although surge protectors protect you from power disturbances, they do nothing to protect your equipment if its power supply is compromised.
