How many watts of accesories can be added before stator won't keep up?

I've read a couple places that the stator on the Xciting 500 puts out about 240w.  I'm running the euro headlight assembly with 21 watt lumen equivalent LED running lights that actually draw 5 watts each which is what the stock euro Xciting running lights draw so I haven't had any charging issues. I did want to add a couple more accessories to the bike (Admore Led kit to the top box, one amp charger for my Smart phone, etc.)  and am wondering if anyone has found the actual headroom on our stators, i.e. we can add "x" watts of draw before the stator will not charge the system when the fan is running.  Testing this with the fan on is obviously critical as any reading with it off would be meaningless and the limit should probably be tested with the high beams on as a lot of us run them in daylight. I have swapped out the 5w license plate bulb for an LED which only draws 1w so I have 4 watts in the bank

I think u would be fine. It's the electric vest and such that over power the system. Charge cell with extension cord from under seat. Fan is not on much unless u ride stop and go in summer.

My cell won't charge well from the underseat socket as I need a 2.1 amp charger (it's a big smart phone) and I think they limit the output of the underseat socket to 500ma.  I am going to try to wire in a socket elsewhere and hook up an led voltmeter to monitor the draw as I add accessories.  I'll report back if and when I hit the addon 'limit' for the stator.
