> One of the reason I don't buy e-juice online is because I truly get satisfaction of supporting the local business that sell them, but when it came time to replacing the 2-bay charger I originally had for original rig there was literally a price difference of more than fifty percent. NITECORE seems to be something of a staple within the vaping community, as I've in fact seen no other dedicated charger sold by another company (at least in my local area) so I wasn't hesitant about the name. All four bays get at least a full-charge of batteries use a day and I ordered this on year ago, so it's sufficient to assume it holds its own for continual prolonged usage.
