I bought one of these as well, and for the most part, I am happy with it. I originally started
vaping with an L88b (Blu/Volcano-type) that came with a PCC. I loved the convenience of being able to charge my batteries on the road, without being tied to a USB port of an AC outlet. I found that I could charge my batteries about 5-6 times before the PCC died and needed recharging itself.
The problem was I didn't love the L88b itself, due to its weak battery life and low-capacity carts. So I switched to an RN4081, which I found to be a superior product. But I did not have a PCC, so its appeal for a "travel" e-cig was limited.
Enter the above-mentioned PCC from AquaVapor. It's as good as the Volcano PCC in terms of holding its own charge and for fast battery recharging. But there is no place to store a fully assembled e-cig, which I feel is a minor issue. Overall, it works as I hoped, and enables me to take my RN4081 with me without worrying about running out of battery.
