This device generates microwatts. You’d need thousands of them in parallel to power a typical mobile phone.
Surge suppressors do not drop extra voltage to ground. They selectively short out surges between whatever two conductors have a high potential between them.
No ground conductor means there cannot be a high potential between it and anything else!
