Great convenient portable jump starter

I got this because I hate dealing with jumper cables, and it’s honestly just made things so much easier. It comes in a compact case so I keep it in my trunk without it taking up space. I’ve only used it once so far but it worked without any issues and was really straightforward. The built-in flashlight and charging features are a nice bonus too.
