E-nail
From Wiki Weed
One of the newest innovations in dabbing technology, these plug-in devices use a heating element and a controller to keep the nail at a designated heat setting. Having full control of the heat on the nail (especially when used in combination with a carb cap) enables lower temperature dabbing, which offers more flavor and greater preservation of terpenes compared to using a torch. There are a variety of companies making similar devices, but the original invention can be credited to Task Rok, head of Highly Educated, which produces a line of titanium products for dabbing.
