A solar charger harnesses the power of the sun to provide electricity to devices or batteries, offering portability.
These chargers are versatile, capable of charging lead acid or Ni-Cd battery banks up to 48 V with a capacity of hundreds of ampere hours, sometimes reaching up to 4000 Ah. They typically utilize an intelligent charge controller.
Stationary solar cells, commonly placed on rooftops or ground-based base-station locations, form the basis of these charger setups. They link to a battery bank to store energy for later use, supplementing mains-supply chargers for energy conservation during daylight hours.
Portable models primarily derive energy from the sun. They include:
Small, portable versions designed for various mobile phones, cell phones, iPods, or other portable audio gear.
Fold-out models meant for placement on automobile dashboards, plugging into the cigar/12v lighter socket to maintain the battery when the vehicle is idle.
Flashlights or torches, often featuring a secondary charging method like a kinetic (hand crank generator) system.
