Well you only charging with 350mA so charging a 2300mAh mugen will take some 6-7 hours if it is close to flat.

In contrast im testing the 1450mAh i just got from avartardeals right now, im charging with 1200mA so it won't take long.

And will post results here as usual, just hope that avartardeals stocks them as im reading about users complaining that they are out of stock.
