The reviews regarding the power output are pretty damning. I like the idea but my concerns about overcharging and overvoltage aren't satisfied.

I can't fully ensure your concerns aren't justified because I never logged the voltage out over time but I have run the 5w version for a few years now. My previous battery was able to stay alive for almost 2 years past the warranty date (autozone gold) until I did eventually run it low and it never recovered. The 5w version is safe for my 2013 truck's electrical system.

it's easy enough to test this with a full battery and a multimeter. these charging chips are so common and cheap that I wouldn't expect overvoltage to be an issue.
