Small USB devices like cameras of MP3 players require 1-2.5W of constant power to charge. Our panels can easily provide this amount of power even in sub-ideal conditions. Smartphones and tablets have a higher power requirement, ususally around 5W of constant power. A 7W rated solar panel will only produce 5W in perfect sun conditions, and because smartphone are quite picky about their power requirements, they can "give up" charging if there is ever an interruption in constant power - like when a cloud passes by overhead.
For the best experience, we recommend using a Goal Zero battery pack as a buffer, instead of charging directly from the sun, for the following reasons:
Goal Zero's mission is to empower people because they believe in human potential. The potential to go farther and do more than you ever thought possible; the potential to provide a sustainable future for you and your family; the potential to make a difference in the lives of people everywhere.

The warranty period for GOAL ZERO battery cells (whether purchased on a stand-alone basis or as part of another product) is 180 days. The warranty period for all other GOAL ZERO products and components is one (1) year. In each case, the warranty period is measured starting on the date of purchase by the original consumer purchaser. The sales receipt from the first consumer purchase, or other reasonable documentary proof, is required in order to establish the start date of the warranty period. If you completed the online GOAL ZERO Product Registration Form within 30 days after purchasing your product, that registration can also establish the start date of the warranty period (but warranty coverage is not conditioned upon such registration).
