Why is there not a dummy battery that houses a 110v AC to 18v
ryobi does build a few "hybrid" 18vdc / 120vac products, like the weedeater. i assume they just wind the motor in a way that it can use both. you don''t understand just how much energy is in a li-ion pack, but heres a possible solution.. 24v 30a might be enough, possibly adding capacitors to handle the surge current. ~$40 plus fabrication costs.
