ZMI PowerPack Ambi Dual USB-C Power Bank: The smallest, dual USB-C port power bank to hit the market.

The original concept struck me in Feb. 2018. Back then, USB-C portable chargers just started to gain traction with users. The few products on the market were primarily for charging laptops. To provide extended battery life and wattage to laptops in a meaningful manner, they inevitably had quite a bit of heft to them. Through my interaction with customers who bought our 20K mAh USB-C PD battery pack (ZMI PowerPack 20K Model QB820), I saw some other requirements that weren't met by any existing products. So, I set out to define a product offering 1) greater portability, 2) two USB-C ports (in anticipation of emerging USB-C charged devices), 3) simplicity and purity (without being bogged down by legacy ports and protocols), 4) Passthrough charging and Uninterruptible Power Supply (UPS).
