RuK™ Pack’s solar panel is smaller than more powerful USB solar panels available; this is intentional as we did not want to jeopardize the integrity of the bag’s design
In direct sunlight, most smart phones can typically be charged at a rate of about 1% per 2 minutes. Larger devices, like tablets, may take longer. Unfortunately, sunlight is unpredictable, which can slow charge speeds
An external battery pack combined with the RuK™ Pack is the best way to charge your USB device after dark, indoors, or in adverse sunlight conditions
RuK™ Battery packs can be plugged in to standard household electrical outlets for the quickest charge
For best results, switch to airplane mode and close all applications running on your smartphone which will help charging time become more efficient
Although they can be of great benefit, we do not recommend Solar powered USB charging products to be used as your primary method of powering devices
