No good to you unless you have purposely built your own house and had 3 core wiring installed, with a circuit going to an earth.
Surge protectors divert the surge to earth. With 2 pin plugs, there's no third cable going to earth. If you are in a condo, nothing you can do about it.
If you are in a house, you might be able to rig something up on the power point where your sensitive electronics are, and where this power board will be.
You could remove the power point, drill a small hole through the wall, and run a cable to a ground outside. Hammer a copper rod into the ground and attached the third cable to it.
Back inside, either try to source an international plug power point or, strip some of the insulation back on the power board lead, cut into the earth cable and join it to your new earth cable, and then insulate the joint and the lead again. You would have to drill a small hole through the power point to poke the new earth cable through. .
The above effectively means you have made a ground for the surge to be diverted to only for that one power point, but since you are using a power board, all the devices attached to the one power point will be surge protected.
