Hey everyone. I live in the UK and have been trying disposable e-cigs. I want to get a more permanent option but am getting lost with all the numbers and letters like mah and omh. I just want a starter e-cig like this one 510 Carto Kit £21.99 - Basic Vaping Kits - 510 Carto Kit Electronic Cigarettes | Vaping Devices | Accessories | E-Liquid. But people are saying something about using low resistance attys can damage the battery. If someone could shed some light on the matter it would be much appreciated!
