Jumper cables are a thing of the past. No more waiting on someone else’s availability or help when your battery is on the fritz.This isn’t my first time using a portable battery jumper. My parents had lent me theirs when I was having some car troubles a while back. It saved my butt quite a few times from being stuck on the side of the road until I could afford a new battery.Now that I’m in a better position and with winter on its way I went ahead and purchased this megawise battery jumper. I appreciate the chart provided in the carrying case indicating the appropriate voltage and engine size it can be used on. I will likely keep this in my wife’s car as she travels more for work.The addition of usb charge ports is also nice if your phone or other device needs charging in a pinch. The led light is quite bright and also helpful in the even your working in the dark and need to find the battery terminals more easily.Coincidentally, my neighbors car had trouble starting the other morning so I was excited to use and demonstrate how great this jumper works. I’m pretty positive they will now be purchasing one as well!
