Remember that watts are voltage x current(amps) The number of watts you can get from a 48V battery will depend on how many amps the battery can deliver and how much the load can draw.
draw 0.104 amps
In normal simple circuits WATTS = VOLTS x AMPS So if you use a 12V car battery 4 amps is 48 Watts American 110V mains 4 amps = 440 Watts English 240V mains 4 amps = 960 Watts

No.
48 hours depending on how much taken
The cool box can be powered by a cigarette lighter adapter. These adapters are capable of 10 amps and the car is protected with a 10 amp fuse. A 48 watt cool box draws 4 amps. 48 watts / 12 volts = 4 amps. If the device drew more than 10 amps it would have to be connected to the car battery directly.
The formula you are looking for is Watts = Amps x Volts. Amps = Watts/Volts. This comes to 4 amps load. Minimum size fuse would be 5 amps.
There were several models of Fender Tweed Pro amps made in the late 50's and early 60's. They weigh about 55 pounds.
When 20% of 60 is taken away from it, you get 48.
48
Not much. Studeis show that a 5 year old could break such a foam board in one shot taken in .48 seconds.

two twice 48 + 48 = 96 96/48 = 2
