Grounded adapter plugs "convert" one type of grounded electrical plug to another... Adapters do not change the voltage.

Grounded adapter plugs maintain the ground from the electrical outlet to your appliance. Adapter plugs are needed because electrical wall outlets around the world differ in shape and size.

Take your USA 2 prong or 3 prong appliance and plug it into this grounded Israel adapter plug so that you can plug your appliance in an Israel outlet.
