This is what makes two-prong outlets the least safe of any type of outlet. Two-prong outlets have connections only for hot and neutral wire, hence their name. Without a third-prong for a connected ground wire, unstable electricity doesn’t have a path to travel safely away from you and your electrical system.
Does a surge protector work if not grounded?
Grounding is a critical element required for proper surge protection. In regard to the question about whether surge protectors work on ungrounded outlets, the answer is “no.” Surge protection equipment typically uses components called metal oxide varistors (MOVs) to divert excess current into the ground line.

Can a point of use strip be connected to a 2 prong outlet?
As for the point of use strips: it’s true most will have three protection devices arranged in a triangle. But keep in mind neutral and ground are connected together at the panel anyway. From a surge point of view the 2-prong is not all that bad.
Is it safe to bypass the 3rd prong?
