OmniCharge Omni 20
One of the several higher-capacity charging products that got its start on crowdfunding networks (and one that didn't leave backers in the lurch), the Omni 20 (20,000 mAh) is one of the world's smallest portable chargers with an AC outlet. It also has an LCD that provides a wealth of status info and a DC output that can be tuned for specific products. One option from the campaign that hasn't made it through to the version currently shipping was taking advantage of its flat surface for use as a Qi charging pad. The company is now working on a nearly identical version with USB-C.
