Generalizing the classical result of Bohr, we show that if an n-variable power series converges in n-circular bounded complete domain D and its sum has modulus less than 1, then the sum of the maximum of the moduli of the terms is less than 1 in the homothetic domain r dot-product D, where r equals 1 minus the nth root of 2/3.
