I’ve tested a bunch of Vapcell cells, but I think this is the first charger. Also it’s been a long time since I tested a charger and so I ended up not testing this one in a timely manner. This is my last remaining 2019 review item. Sorry Vapcell and thanks for being patient! Also I’m stating up front that my charger reviews are likely going to get scaled back. In this case I’m basically testing the main feature, which is the ability to charge 4 bays at 3A each!!
