From the research I did there is a very wide amount of wattage ratings for box fans. From one that I saw that was down at 35 watts to some that were up around 175. Plus conditions that the fan is used play widely into that and there is a large margin of error on the rating that the fan would have on the motor.
The Duracell PowerPack Pro 1100 # DU76FR has an internal battery that can provide up to 12 amp hours. So at 1 amp it would last 12 hours.
Converting 1 amp to watts gives you 92 watts. So without knowing the actual wattage or amperage of your box fan I can only really say that it would last around the 12 hours, but most likely less.
