The handheld Tesla coil is a Tesla coil powered by battery and DC voltage converter. It is portable and mobile, no longer limited by the disadvantages of traditional switching power supply, which can only be used in fixed occasions. After the changes of the previous two generations, the third generation official version has undergone varying degrees of optimization and adjustment in the selection of components and careful debugging of parameters, as well as in the use of materials for the exterior shell. Especially in this generation of version, gold-plated functional panels and customized handles have been used at all costs, resulting in a fundamental improvement in appearance and user experience.
