Question If each VoiceTone Single pedal needs 400 Milliamp to run and the Singles Connect Kit should power four of them, wouldn't that mean that a 1.6 Amp power supply is needed to give sufficient power to four pedals Answer This is a logical conclusion. However, due to the daisy-chaining, only the first pedal in the signal chain is going to be making full use of its pre-amp and therefore, a 1 Amp power supply will suffice. In short, have no fear: it is designed for four pedals, it will indeed power four pedals!
