Natchez Premier Power Bank is a compact power bank. It is much smaller in size comparing to the other 10,000mAh power banks as it has a high density battery inside. However, it charges your device super fast with an 18W quick charge (QC) and power delivery (PD) technology. Though compact in size, Natchez has two large fabric finish “canvas” sides to carry your entire marketing campaign.
