After the coil is fully charged, the Power Core is automatically is inserted into SpiderBot, giving it 1000 power. The max amount of power per second (pps) used to charge the coil is 33.2 pps. A power supply equal or greater than 33.2 pps will charge the coil in 25 seconds. Mathematically it will take a total of 830 power over 25 seconds to give SpiderBot 1000 power.
