yes you can if you know what your doing
Considering that this is in the car starting problems category, I am assuming you mean a Jump Box to start a car. In this case, a jump box is a device with a battery and attached cables that can be used to jump start your car. This is used when a car battery has died. Another alternative is to use jumper cables with another car.
Hook the cables to the jump start posts under the hood. They are labled with a + and -
Use jumper cables attached to either another car or use a jump start kit. If the car has a manual transmission, you can push start it by turning the key, putting the car in 1st gear, pushing it and then popping the clutch.

A 1996 Buick Regal will jump start using a portable battery pack. Another person can also use jumper cables to help jump start another car.

Well you should use the emergancy break or jump out of the car when you have the best chance.
a trickle charger will not jump start anything,however if it is left connected long enuff, and the battery will take a charge, the mower should start. to jumpstart, a mower, you can use a car the same as you would jump start another car. just make sure battery in mower is 12 volt same as car
D.C. current is the only current used in your car. If you jump a battery from another battery, that's D.C.
You can use jumper cables, but cars with automatics shouldn't be towed or pushed as an attempt to start them. It can damage the transmission.
The Liberty Mutual Solutions site has step-by-step instructions on how to jump-start a car battery. You can find those instructions (and download a how-to PDF) in the related links below. Here are some safety tips to remember when you jump-start your car battery: -ALWAYS wear eye protection or eyeglasses when you jump-start a vehicle. -ALWAYS make sure the cables will be clear of any moving engine parts when the cars are started. -NEVER smoke while jump-starting a vehicle. -ALWAYS start with the ignition in both vehicles turned OFF.
As long as both batteries are the same voltage, you can jump start with the battery. If you want to charge the battery then use a battery charger.
