 and I know this from experience, like the solar ones that are all built in and they've got the jumper cables on them and they're a regular full size with the handle. Here's the other caveat. When that battery in it goes bad, you can go to Amazon, take that apart, or Napa, buy a new battery, put a right pick inside of it, and you're not buying a whole other jump box at the end of the day. So your long-term use is going to be substantially longer than the small units are.
