umm. im pretty sure my mme just came with a 4pin > power cable for the mme. might have been a hacked wal wart with a 4pin attached as i didnt have a wal wart for it
if you have any power cable for it at all, then you can hack it if you would like. or wyou could buy a mme power cable from alot of the taper related retailers
go to rat shack, but a set of the rc type plugs (you will get one male and one female) solder it onto the power cable (whichever one fits the battery correctly, i cant remember if the bat end is female or male) and you will be set to go
feel free to pm me, powering the mme with rc packs or the wal-mart l-ion pack is the only way to go
at this time i would siggest the wal-mart l-ion pack
