How Do You Hack A Hand Cranked Flashlight For Emergency Power?
• Take apart the flashlight with care. • Inside you will find a small hand-cranked generator and some button cells that generate power. • Obtain a 12 volt car adapter. Ensure that it fits the item that you want to charge (for example, a cell phone). • Cut the end off, leaving the end that plugs into the phone or other appliance. • Check the polarity. • Solder the wires of the 12 volt adapter to the two button cell contacts. See Warnings. • Cut a notch in the plastic of the flashlight to fit the cable. Seal up the flashlight. • Put the connector in and see if it will charge your cell phone or other appliance. • Crank the flashlight. Look for the charging symbols on your phone. Try other appliances, such as a PDA.
