I have seen boosters that have a slot for a DC plug
what's a booster, a battery booster?
yeah the ones you use when your car won't start
Battery boosters are pretty big and need to be constantly charged as they drain rather quickly. To charge them usually requires a cuple of hours IME.
yup and bulky... wish there was another way
Install a deep cycle battery in you car.
You looking for a camera? Why not install on your house?
Explain how to..
Sorry, meant to be a joke.A deep cycle battery is meant to be drained down and charged on a regular basis (as opposed to a car battery, which is really only used to start a car...while the car is running, the alternator (getting energy from the motor) provides all electricity.)
so what is a deep cycle bat usually used for?
