I am trying to hook up 20 bouncing tiggers. All the same toy. Each has 4@ 1.5AA batteries. THey have Duracell Alkaline in them. I tried a battery replacement for a ps1 game unit but it is only 4.5 vDc and for some reason you had to push the trigger (hand) twice to get it to activate. The toy Bounces up and down and sings the tiger song for about 10 seconds. 6 volts per tigger. Will one regulated power supply do or should I buy more than one. Thank you, Kim

A standard Energizer alkaline AA batery has 2.85 Ah of charge capacity:

Generally, you'd want batteries to last at least a couple of hours, so assume that 2.85 Ah is spread over 2 hrs, resulting in an average current draw of 1.43 A per Tigger. 20 Tiggers would be nearly 30 A.

We are not designing the tigger, its already there. Q is: how long does it operate on a fresh 4XAA batts.
Then use the 2.85A info given by our co-member and calculate ampacity.
However, regulated p-packs should work, and u need enough to complete your 6V per set.

What you really want to know is how much current each toy draws. Just borrow an ammeter and measure it with a fresh set of batteries or stable 6V power supply.
