Answer:
Depends on usage. If you are asking how long it holds a charge. I pull mine out of the car every 3 months to keep it topped up and it is usually at 97%. If your asking about using it as a power brick for charging a phone. I will charge a Galaxy S9+ about 5 times.

Answer:
I've used it to jump my 4.0L Toyota Tundra with no problems and recently used it to jump a '65 Toyota FJ40 that had no battery and had not been started in 3 years. These things are pretty amazing.

Answer:
It will work but have to keep pushing the button, not sure it would last all day. I ran a winch with it doing 30 drop tests and it lasted for all them.
