I got my black MVP Pro 3.0 60W in the mail yesterday. Haven't been using it exclusively but fairly regular last night and today, and still the battery reads over 3.90V, super battery life in this thing. It was fully charged when I got it, and I am going to see how long I can go before it requires recharging. I use a 0.5 ohm head around 18-25 Watts so not a lot of drain on the battery, but still holding better than I would have thought.
I only have the CF-IV to compare it to so here goes. I like the larger OLED screen since it makes it easier to read. In the sun it washed out more than than the CF-IV does but still readable. Buttons all work the same as the CF-IV so there is no learning curve. The buttons don't rattle on either
mod, and are nice and clicky. Form factor isn't as good as the Coolfire IV, little harder to carry around and doesn't fit in the hand or pocket as well, but that's what I expected, after all, it's a box. One negative, with my Subtank mini there is a slight delay between button press and actually firing.
Overall it seems to have power for days which is what I was after since I will be in Cancun for a week I needed something I didn't want to worry about running out of charge midway
through the party. 4500 mAh was the selling point that got my attention,
innokin's quality with the CF-IV sealed the deal. As someone stated above, I feel like I can use it as a weapon if needed, this thing is a brick. I showed it to my brother and he was so impressed I purchased one for him, he wanted a blue one.
