Brian,

That page seems to suggest PS wattages that I think are too low? I have a 400w PS that I use with my 1210i. When charging a 5S at 8A, the PS voltage drops to around 11.5v or so. The most conservative value of PS your page suggests is 281w, which I'm not sure would do the job.

Now, my PS may be junky, but it was a $75 PSU (which was on sale for $59, with a $59 rebate, go me! ) so I'm pretty sure it's decent at least. I don't know how much more it would dip under load, maybe this one's just poorly regulated/

Not bashing, just an observation.

Sleeb
