3 out of 5 eggsOne weak link

Pros: A mostly impressive unit with high-grade battery, great air compressor and hoses. AC out is a great feature and an air pressure gage is a great addition. It's an awesome thing to have for minor problems as well as more serious strandings or power failures.

Cons: Wall mounted power supply destroyed its self after a few months. Now what am I supposed to do with a battery that can't be charged? The high-grade battery is an AGM type so you can't safely charge it with a solar panel that has a car adapter on it. I wanted that capability so I'm disappointed with that. The internal charge controller is not good enough for that type of battery so the instructions tell you to charge it all the way but not leave it plugged in too long. Had I known this I would have skipped this product immediately as I want something that can keep plugged in without destroying its battery. That was a serious cheap-out on the designers part.

Other Thoughts: With the power supply that failed, the lack of a proper internal charge controller, and the limitations on charging solutions this is a problem solving device that is rendered useless by one simple weak link.
