Feynman Promotional Power Bank with 2019 Update

Feynman Power Bank with 2019 Update


The sturdy 20,000 mAh Feynman Promotional Power Bank is one of our highest capacity power banks. It has a smooth rubberized exterior, and is available in black and white. It has three charging ports, one 1A and two 2A, and with its ultra high capacity, has more than enough power to use all three at the same time. All of the ports can charge most smartphones six to eight full times. Its 2A ports will charge any common tablet one full time and will charge many tablets multiple times. In addition to the three output ports, there are three input ports as well. The first of these ports is the 2A “normal” Micro USB port for charging using the cable that comes with many small electronics these days. It also has a 1.5A Lightning input port, for charging using an Apple cable and a 2A USB Type-C input port. There will be no trying to stick the Type-C cable into the Lightning port, because each port is clearly labeled on the back of the power bank. Dimensions are: 7.75” x 3.75”. US Patent Pending.
