The Lavatube, is pretty much a Chinese one off of the Provari. Being Variable Voltage, you can adjust it to the power you want. It uses the popular 510 threads on the atty connector. for the price of a Lavatube, it would be worth the try, as it is not that much more than a standard starter kit.
I would suggest ordering an extra IMR battery if you decide to try one of these. Even though these big batteries last a decent while, it sucks to have to wait for it to charge.
Another popular device like this is called the "Darwin", only it is a variable wattage device. With it, no matter what the resistance of your atty, your output will remain the same, based on your desired setting. Just be prepared to pay a pretty penny for it.
