Powerbanks are rated in mAh (milliamp hours), just like the battery in your cellphone. They have about 70% to 80% efficiency; the rest of the energy is lost to heat. This means, for instance, that a 3600 mAh powerbank wouldn't completely fill your S4's 3600 mAh battery. Even a 4000 mAh unit would fall a bit short (do the multiplications - even 0.80 x 4000 is less than 3600). On the other hand, you'll probably hook up the powerbank before your battery is completely dead.
