The Apollo 2000 solar loader looks like a wonderful product for the filmmaking community production needs. It's a solar battery charger compatible with many accessories like cellphones, Bluetooth headsets, MP3 readers, iPod and iPhones, video game consoles and some digital cameras, and with its small size it can be taken everywhere with you. Solar energy is plainly said good and cheap (the energy supplied by a "free" sun and the retails prices of solar panel products are not as costly as it used to be). The charger is also a hybrid product as it can be reloaded by the sun or more ordinarily by electric power at an affordable retail of 60 Euros.
