They actually don't need the input voltage to be higher than the output. I've always run mine off a 12v xbox 360 power supply and used it to charge batteries higher in voltage. The specs for the charger I linked to says the input voltage range is 10-28v, so that 10v lower limit is probably what you ran into.
