The Kickstarter website keeps fundraising for a serial production of the Pocket Sun portable battery. What makes it different from the countless number of analogous devices? This product can replenish its power reserves by using sunlight, heat and motion.
Pocket Sun includes thermoelectric, kinetic and solar generators, and its capacity is 2500 mAh. Not as much as we would like to have, but it is enough to extend the life of a smartphone, a smart watch, a fitness bracelet or a tablet when needed.
A USB-port or a wireless Qi technology is used to connect the mobile device. The product has very compact dimensions – 8.9×8.9×1.8 cm. The cost of Pocket Sun for pre-order is $89.
