Review on TP Solar10 Portable Maintainer Cigarette Alligator by Lucas Hale

As I work in electronics I decided to measure the voltage before trusting it to charge a car battery. In bright sunlight, the green "Normal Operation" indicator on the control panel would illuminate, indicating that the unit is on. I measured 0/0.00 voltage with each of the included wires. In other words, this panel is of absolutely no use when it comes to battery charging. Use a voltmeter or test lamp to test your panel as you may have a false sense of security.
