The SunJack 14W Panel set is useful for the less dedicated device user that still needs access to their device at any time. 14W panels are enough to charge mid-range devices and the included battery pack allows for night charging without jumping through hoops.

Pros
Pro Additional pockets and bands can carry devices
Multiple options for holding devices allows for charging without having to come up with unnecessary carrying methods.
Pro Included battery allows for usage in more versatile conditions
This package comes with an 8000 mAh external battery that can be fully charged by the panels in a reported 5 hours—impressively fast—and allows device batteries to be charged under less-than-ideal weather conditions or at night.
Cons
Con Poor price-to-watts ratio
Inclusion of a battery has pushed the price up to surprisingly high levels, despite the panels producing less wattage than competitors. If the user doesn't plan on using the battery, or already has a high-quality external battery, this may not be the most effective option.
Con External battery means more cables and small components
The inclusion of an external battery can complicate carriage by adding additional cables or pieces that can be lost.
Con Larger size with lower voltage than competitive panels
Other panels can produce more current with a smaller profile, and the included clips are less versatile than the eyelets that are often included with other models.
