Well, by the specs, it can supply 18A on one of the 12v rails. According to
this, to utilize the full potential of the 1210i, you'd need at least around 25A. If you don't charge the max cell count at the max current, you might be ok.
Note how that PS has dual 12v rails. Most of the time, you'd be better off finding a PS with only one 12v rail since the current will be greater. Also, the cheaper PS units tend to drop their voltage when drawing the rated current to the point where the charger might not like it. It's not uncommon for the 12v output to drop below 11v under high currents.
This one would suit you better IMO. I know it's getting a little pricey, but high currents aren't cheap. Note how it is good for up to 34A. That means it will most likely maintain a more solid voltage at "only" 25A.
Depending on the unit, there may be an internal potentiometer to tweak the 12v line to something a little higher, say 12.5-13v. Higher voltage will make the charger pull a little less current.
