DEVICE HOLDER AND SOLAR POWERED CHARGER UNIT FOR SMART DEVICE COOLER

A solar powered cooler for a smart device such as a smartphone or smart tablet is provided, optionally with a device holder and a solar powered charger unit. The cooler may include an upper fan casing, an optional bottom fan casing, smart device holder, and an air passage formed between the upper fan casing and the smart device holder. The heat dissipation structure of the smart device holder for holding a smart device is disposed in the close proximity space of the smart device to provide a good heat dissipation effect by way of active cooling (forced convection) and passive cooling (natural convection) so as to enhance the heat dissipation performance of the smart device.
