Sorry, my mistake....the car charger I bought was from Radio Shack, I can't remember where I bought the wall charger. The product name is "Rocketfish". It has no UL or CE listing or markings. Doing a quick search I didn't see any particularly bad reviews. Still, with all things in perspective, while on a rare occasion a wall charger will malfunction and fail, rarely would the malfunction escalate and cause a fire or electrocution event to happen.

Regardless, these things are cheap and mass produced with likely little to no quality control. I think it's in my best interest to unplug it when I leave the house. I might also rethink using it while I sleep although I've never had any problems with it. My reasons for doing a 180° flip-flop, simple; I don't trust cheap battery chargers for charging my bike batteries while unattended so why should I trust these cheap phone chargers? Oh I still plan on using them but I'll be home and wide awake when I do. In the mean time I might see if I can find a plug-in circuit breaker/Surge protector to use with the phone charger just to keep things a little more safe.

...now if they make a UL listed phone charger with built in 1A circuit breaker I'd like to get me one of those.
