Solar Power Guide

Please Note:

• 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
