A box mod, in short, is an e-cigarette that has the shape of a box rather than that of a cylinder. The term “mod” comes from the fact that all of the earliest e-cigarette mods were either built by hand or made from modified household objects. There were box mods made from Altoids tins, snus cans, craft boxes — you name it. People found items big enough to hold batteries and simply attached buttons and atomizer threading.
Today, box mods are highly polished consumer products. They include safety features, variable wattage settings and custom temperature controls. The earliest box mods had virtually no internal electronics — just a few wires. People made them because they were tired of the poor battery life and vapor production of the cigalikes available at the time.
The truth is, though, that the earliest box mods actually had quite a lot in common with the box mods of today. The earliest mod makers tended to use 18650 batteries and 510 atomizer threading. Most box mods still use those components today. In fact, the 510 thread is now so ubiquitous that you don’t even need to understand the term — virtually every tank or atomizer today uses the 510 connection. Back then, the 510 thread was just one of a great many choices. Sadly, I don’t think there’s a patent for the first box mod!
