...Not unless you want an explosion! Wall voltage is 120v AC and up to whatever the circuit breaker/wires will handle (typically around 15A). You need a 12v DC supply capable of a current for whatever charger you need.
i already made one a ps but sold it... stupid me... and so now i need another one... i actually was trying to find that thread and even searched the words "power supply" but that didnt come up!
Well I meant you probably would've electrocuted yourself eventually. Either when you made the plug and first put it in the charger, or after you plugged it in and saw smoke coming from the charger and went to rip it out fast and forgot it had 120V behind it. Especially with a Deans plug, not much insulation there to keep fingers safe.
