INPUT People: Eesha Khare created a charger that charges a cell phone within 20-30 seconds. But the first person who invented the cell phone charger was Martin Cooper of Motorola.

Information: It sends an electric current through it forcing the battery to recharge.Tools & Machines: Machines make everything that goes into creating a phone charger, people are used to watch over the machines and make sure there are no errors. Sometimes people miss the mistakes because I recently bought a cell phone charger that did not work at all.

Energy: To get the energy to the phone you have to plug it into an outlet which then takes the energy and recharges your phone’s battery.

Capital: About $4.Time: Eesha Khare created one that will charge it in about 20-30 seconds, but it typically takes about 2 hours to get it from 0%-100%

PROCESS•The cellphone charger extracts the power from the home supply (AC 220V) and converts it to a DC level of required voltage.
