I would like to see MadVapes carry ego sized ecigs that are actually 4.5 volts.
I would like to see PTs and ecigs a little more compatible, but a 4volt regulated PT may be more costly and cumbersome, and the 5v PTs are not too problematic, so I think batteries could use a little more voltage. So asking manufacturers to make ego sized ecigs that operate from 4.5 volts (fully charged), down to 3.5v would be something good, even if they're only 400mah instead of six or nine-hundred. I think when they made the 900mah egos and 1300mah Hellos they got carried away with the milliamp-hours, but failed on the volts. What we need is a better balance.
