got the charger yesterday and was a little flabbergasted. The wall part always is green and the charger itself is always red. Seems like this is not the most consistent product. I took it off the charger after about 4 hours and it had a charge of about 5.75 on my multimeter. So from an earlier post i guess this is about what the nominal charge should be. Unlike everybody else my battery was not hot. Cant say i am very comfortable with the quality of this charger, but i love the 5volt battery on my Phidias with an IKENVAPE 3.5 atty. I will
buy more of these but would hope that a better charger becomes available. I guess no one has had one of these suckers explode, which makes me feel better as well.
