Product use precautions:

1. After the transformer is successfully manufactured, it must be sealed with epoxy resin or insulating wax for long-term use. In the air-loaded operation, the coil breakdown will be damaged due to insufficient air insulation strength!

2. After the kit is successfully manufactured, the input voltage is 3.7V, that is, the 18650 rechargeable battery. If you need to increase the input voltage, you need to increase the resistance (the default resistance of the kit is 150 ohms), otherwise the triode will burn out easily. (maximum boost 12V)
