Solar Panels use an alternative, inexhaustible energy source. External and replacement batteries require access to AC power in order to recharge, using up precious resources. Solar Systems contains no lead, acid, or nickel-like batteries. Predicted life expectancy of the solar cells is over 20 years whereas batteries will only live for about 500 to 900 charging cycles. Solar Systems offers a full one year warranty and a thirty day money back guarantee.
Most batteries offer only a six month warranty.
The Sun Catcher Professional has a cigarette lighter socket built-in as its power connection. They will recharge both ni-cad and alkaline batteries, in AAA, AA, C and D sizes. All dimensions are while folded. With panels deployed, the Sun Catchers are twice as wide and half as thick as listed above. The Sun Catcher Professional and Expedition models support pretty much any device that is battery operated and has a cigarette lighter adapter unit available.
