Wow! This is one impressive machine! I have a Halo, but this is even faster, and stronger! After you hook up the jumper cables, you don't even have to push any buttons... You just start the engine of whatever you are jumping, and unplug the cables! You can charge your phone, tablet etc. It also has a bright flashlight, with stay on mode, or strobe! The unit isnt heavy, and isnt too big! It has an easy handle for carrying! I keep one of these around all winter, here in upstate ny. I've had to use one multiple times, and they definitely pay for themselves with one use, if your stuck out in the winter with a dead battery! I highly recommend!
