I don't have that specific charger, but I do have an older Hyperion EOS7i. When I want to charge a higher charge rates, I trick it by saying I have a larger lipo than I do. Example: If I want to charge a 3s 3300mAh pack at 2C, I would tell the charger it really is a 6600mAh pack.

However, that power supply is rather weak. 12.5A @ 12v is only good for around 150w, and after taking charger effiencey into consideration, is only good for 120w. That would limit the charge rate depending on the lipo. And that assumes the output is a steady 12v at all loads; most power supplies drop voltage under heavy loads, which means the charger has to pull more current to compensate. For the 1210i (which is rated for 180w), I would get a power supply no less than 20A @12v to use it to its full rating.
