Most cable modems operate at 10-20W. Assuming 20W, you will get approximately an hour of run-time depending on environmental conditions. If you look at your power transformer (power supply for your cable modem), there will be an output voltage and amperage listed. Take the volts times the amps to get your actual wattage.
