Most camera cradles require more than 6 volts to be able to charge up digital camera batteries. While most of our products can provide more than 6 volts, there are a few exceptions.
Will charge digital cameras: Amp, Fuse 4W, Fuse 10W, OffGrid, Array, Spark Tablet, Generator, 6-12V Kits, 18V Kits.
Won't charge digital cameras: Fuse 6W, Converter, Switch, 6V Kits
Most of our solar chargers with 4-8 Watts (Amp, Fuse 4W, Switch, OffGrid, Spark) of solar power will charge most digital cameras directly from solar. Our solar laptop chargers with more power (10 - 16.8 Watts) will charge digital cameras faster and, in addition, charge larger devices such as laptops.
