Here's a preview of the Vapor Zeus from Vapor4Life. This is a slim and easy-to-use e-cig that's surprisingly powerful. Battery capacity is 900 mAh and output is 5.0 volts. While I've generally graduated from cig-alike products, I was pleasantly surprised by the satisfying vapes the Vapor Zeus delivers. That said, I still need to spend more time with it before a full review.
