What are some devices with a long battery life we carry?

Some of our higher mah (milli amp per hour) devices would be the Vision Spinner, version 1 and 2, which have a 1300 mah battery for the spinner 1 and the spinner 2 having 1650mah, so you would have enough battery to vape all day long. Also our E Leaf box mod has an internal 2200 mah battery ensuring a long lasting battery with a small, solid feel to it. A higher quality device like the Provari would take an external battery with batteries with 2500 mah.
