u got me thinking now man, well anyways i think i`ll take my chances its too good a charger not to buy coz of a power supply :) and one more thing all the website that sell these 1210is say that they are A123 capable and the manual doesnt state that, so maybe the Voltage range got updated when this feature was updated.
It sounds like you did make up your mind and I absolutely love my 1210i but just don't get your hopes up on the power supply being that wide range. Mine is the new A123 version and print on the case as 11-15. Get it though it is an awesome charger, it will do every chemistry on the market.
