My EGO fast charger works great with my authentic Joy EGO but it's very finicky when I use it with an EGO knockoff I also have. I think I may have figured out how to get it working each time with my knockoff (without too much hassle). So if anyone is having an issue where it does not get a connection (no three blinks) here's what I do.
First clean/dry both the charger and battery connections with a paper towel or q tip (actually you should do this each time prior to charging)...if that still doesn't work then grab a toothpick and stick it in the circular groove within the charger's connection and just scrape any gunk that's in there. This seems to get the connection working and charging very good.
