Vaporesso Renova Zero Kit has marked the scale even higher for refillable POD systems. The main advantage of this system is that it provides a new kind of Child-Proof Filling System, known as Press to Fill Mechanism (PTFTM) that is relatively simple to fill, as the name implies, and it lessens the leakage to a greater extent. Vaporesso Renova Zero Pod System has an inner battery of 650 mAh that reduces the charging time to only 45 mins. The micro-USB port can be found at the base of the device which is satisfying and of high quality.
