using the janty eGo that come with 510 attys since April 14, in that short distance the charge/life has been consistent and produces great vapors till the charge gives out (usually around 12-14 hours for me at medium-high vaping) and charge takes like 1 1/2 hours. Only experience I can give being this is the only E-cig I've tried aside from the crappy disposable ones from my local store. Hope you get all your kinks worked out with the E-cigs and get your current one working like a champ. Regardless of the model, if a product will deter one from smoking analogs, more power to ya!
