Negative Positive
Title: No Overvoltage protection
Review: I have used this on planes and it worked with my laptop. Really like its small size. Today just plugged it into a solar panel that puts out 12V (but has large voltage range) and it started to smoke. So I took it back to my car and after it blew out more smoke continued to work. Reading the spec, the input voltage is 12.8 - 13.2 volts - which is pretty tight. I shouldn't have plugged it into the solar array because the voltage with no load is probably like 14-15V, but come on. Its not that hard to design a circuit to handle a higher voltage input. Car systems are known to have lots of strange noise and voltage jumps. So I give it 4 stars because while it smoked, it continued to work. I suspect a couple parts are a bit crisp on the inside. Going to purchase an inverter with over voltage protection.
Is the review positive or negative?
