I just meant it lasts longer. I know the HG2 ratings. For my vaping style, 30 to 50w the Efest or the Samsung 30Q outperforms the LG. I set my puff counter with the same tank and mod and see how much they last. I don't like the performance of the HG2.What are the "alleged" specs of your Efest? Did you cross reference that model and specs with a review of that model of Efest by Mooch's test results?
A little hard for me to understand how an Efest could outperform an authentic LG HG2 3000mAh 20A, unless the Efest has a higher amp rating and you are vaping over 65 watts. The HG2 (at 20 amps) has a wattage limit of 65 watts.
