You guys nailed it! No one else has Provape's patented AccuSet Technology chip set. Hense the "set it and forget it" slogan. You wouldn't know when to change the battery if it weren't for the blinking fire button, as there is no drop in vape quality as the battery drains.
"Our variable voltage ecig has a regulated output which keeps your selected voltage the same with each puff regardless of your remaining battery power.
As the battery drains, the ProVari ecig will keep the voltage consistent giving you the perfect vapor throughout the day.
ProVari with AccuSet technology - Our built-in dynamic self-calibration algorithm keeps the output voltage accurate to 1% or better over the life of the product. The ProVari will constantly monitor and adjust itself to ensure you always get accurate voltage settings. Now a ProVari owner can tell another ProVari owner to try a certain voltage setting with their favorite brand and flavor of e-liquid and the flavor experience can be shared. Every device will autotune itself so it's always precise!"
I dont mean to burst any bubbles or anything, but someone who knows the inner workings or a voltage converter might call that creative marketing. I'd venture to say that they won the patent for being the first to adapt the technology to e-cigs, not because it was a groundbreaking discovery in the world of voltage regulation.
It's not that the Provari has "AccuSet Technology" or that chinese mods dont. Any quality voltage converter will do the same thing as the Provari. It's called a feedback loop and has been in use LONG before the Provari was even a concept.
Monitor the the output voltage, adjust accordingly, repeat the process thousands of times per second, when the voltage can no longer be kept within tolerance...shutdown. That's a feedback loop in a nutshell.
Chinese mods use a feedback loop too, but it is implemented in a different way. What makes chinese mods lose voltage as the battery drains is inferior components and an inferior conversion process (the entire process is different than the Provari, chinese mods essentially have 2 converters, a boost converter immediately followed by a buck converter instead of just 1 integrated boost-buck converter). As the battery drains the amp requirement from the battery increases. Inferior components cant handle the amp requirement so the chinese boost converter isnt able to achieve it's goal of 6.0V and output voltage suffers.
