Sunstream Solar Charge works. Simply point the charger into direct sunlight and you have a charge. As simple as that. It was great a privilege to work on such a fun, simple shoot with Jacques Marais, Peter Kirk and all the patience extras that stepped in. It will not surprise me if Jacques works on these too. Direct sunlight = Supercharged
These powerful devices are:
Fast-Charging: Charge your mobile device or battery on demand in up to two hours. Charges many devices as fast as a wall plug.
Durable: Drop-tested, shatterproof glass face, heatproof, freeze-proof, UV stable, UL Certified photovoltaic module.
Waterproof: Water problem eliminated. So moisture resistant it even works underwater. IEC 60459 Certified.
Portable: A new ergonomic form factor that is pocketable and hand-held. Feels like a mobile phone in your hand.
I use the SunStream Plus. You can also read more about them on their website.
