As the push for renewable energy sources begins, companies are compelled to improve the existing technologies. Such push enabled Suntrica to launch three portable solar chargers for mobile devices: the SolarStrap, the Solar Badge, and the Solar Badge Pro.
As the name suggests, the SolarStrap unit comprises of a device that can strap around an accessory, by folding. One section of the strap contains the photo-voltaic cells, while the other one has the battery and an output port. In order to fit in any phone, many adaptors are provided with the package.[Image: suntrica-solarstrap-live-images-4-300x199.jpg]
The device is light and flexible. The fact that it can attach itself to any accessory made it highly portable - we decided to attach it to our camera's bag. (The bag does not come with the SolarStrap; it is there merely for illustration purposes).
The electrical component of the unit has battery capacity of 3.7Wh/980mAh. We charged the battery of the SolarStrap for an entire day against a clear blue sky's sun, and let a Nokia N95 unit's battery (950mAh capacity) drain completely. The result showed that the SolarStrap was not able to fully charge the device, which only achieved 5 out 7 bars, and it did the charge at a slow pace.[Image: suntrica-solarstrap-live-images-2-300x234.jpg]Official specifications also note that the SolarStrap is able to harvest 50mA of energy under a blue sky, 35mA under slightly cloudy, and 20mA under cloudy. The device cannot be charged from any other power than the sun, according to the information and equipment available.
