Review on FCONEGY Intelligent Car Jump Starter by Tingate Skrbec

While this works for most people with a slightly dead battery, it doesn't work unless it detects your battery has a charge. In other words, if your battery is 100% dead, it won't jump out of the car. I know this is the device's fault as I replaced it with a less intelligent set of cables and was able to jump out of the car with no problem.
