I ordered an adapter that was rated 1000ma max (from Monoprice) didn't work to heat the atomizer (the led worked), I then ordered another from Ebay that claimed 1000ma it came but was rated 500ma max and needless to say didn't work, that one is on the way back (after some strongly worded emails

).I need a link to something that's known will work on a m401 atomizer. Any help would be appreciated. I would like something inexpensive of course...
