The charge of the electron is about -1.60217733 x 10-19 C, the charge of the proton is equal and opposite to that of the electron, both charges are constant.
1 An elementary charge -- that of a proton or electron -- is approximately equal to 1.6Ã10-19Coulombs.  Unlike protons, electrons can move from atom to atom. If an atom has an equal number of protons and electrons, its net charge is 0. If it gains an extra electron, it becomes negatively charged and is known as an anion. If it loses an electron, it becomes positively charged and is known as a cation.
