I think so. I have a N2 intellecharger and it's been reliable, and a backup charger which I never hope to use. I'm afraid you'd have to cut your losses on this one, unless you are willing to charge any of your mods via USB port (which really isn't recommended but you can I guess, for a few days, some folks do it if traveling and etc, but unfortunately, I think yours is toast. I actually really like my N2 intellecharger and wouldn't be dreadfully opposed to having two, honestly, although I also hear good things about Xtar.
Best of luck, and I hope you can wrangle something other than smoking until you can replace it. Sorry to hear about it!
