The Tesla Invader III has the power capacity for 240W. It draws power from two 18650 cells but obtains direction from a PCB. This microchip allows the mod to reach no more than 240 watts, 8.4V and 45 amps. There is a high-tech microchip inside the mod which prevents damage and destruction. A warning from the LED light built into the frame will flash if something is amiss. The battery door is held together with several magnets and there are ventilation holes at the base to help prevent overheating in the battery compartment. The Tesla Invader III is a very simple device to use and is light and a comfortable size to fit in the hand.
