The EM4 is rated by eastmall as being 280mAh. All the actual 401 manual
batteries are rated at 200mAh.
I still haven't seen anyone compare the 2 to see if the EM4 really lasts that much longer. But I have talked to a few suppliers about this, and one asked his smoore rep about it. The smoore rep checked on it, and told him it's not possible to fit a 280mAh battery into a 401 sized e-cig, and that eastmall was full of it.
So either the EM4 will last 1- 2 hours longer then the same size m401 manual battery, which would mean it really is 280mAh. Or Eastmall really is full of crap and the EM4 is the same 200mAh as any other 401 manual battery.
Enquiring minds want to know.
Personally, my 401 manual
batteries last between 3 and 4 hours of pretty consistent
vaping. So unless you people with the EM4 are getting 4.5 - 5 hours or more, I would say eastmall is full of it.
Sludge, you have the EM4. How long does a full charge last you?
