It came with a 74% charge so you can use it right out of the box. Mine was fully charged in less than an hour. It's simple to use. The jump starter doesn't have a very protective case but I dropped mine from about 2 feet or so onto the pavement and it didn't seem to hurt it. The Carry case is great and the clamps that connect to the battery are heavy duty and connect to the battery terminals tightly also the jump starter itself feels well built in your hands not cheap and all of the connections to the unit are sturdy. I've used it to charge a few things and to start my car a 4.7 liter v-8 and so far it's worked great.
