Every cell phone needs a battery to operate, whether it is a NiMH, NiCad, Lithium Ion, or Lithium Polymer. This photo shows a USB travel charger with a lithium ion battery. Lithium ion batteries are the most common form of cell phone battery.
All cell phones must have a battery and a way of charging that battery. Many cell phones come with cords for charging the phone directly from an electrical outlet or vehicle cigarette lighter.
Cordless drill kits like this yellow one come with a strong carrying case and often include a variety of drill bits, screw driver bits and a charger. Some kits may include extra batteries and other accessories.
