Does anyone know of a way to power a 24-840 kato switch controller without a kato power pack? I'm using a Zeyphr and im guessing it cant power it. Just looking for a more compact setup without have 2 power packs around. Want to also keep the kato switch controllers as my kid loves throwing them. Im guessing the kato switch controllers are momentary and if i plug a battery that would burn them out? anything I can jerry-rig with something like this 24-842 dc adapter that would be compact and small?
