About Us

At ZMI, we aspire to improve people's lives by keeping their mobile devices fully charged anytime, anywhere.

Our Mission

Mobile devices have become an essential part of our lives. Whether it’s checking the weather or following the GPS while driving, mobile devices and apps have made our lives a lot easier. Despite all the ways phones and tablets have enhanced our lives, they are still limited by their small batteries. When our devices run out of power, it not only causes temporary frustration but might also stop us from connecting with our loved ones or calling for help in an emergency. Our mission at ZMI is to create simple, elegant, and portable charging solutions that meet your everyday power needs, so you'll never have to worry about a dead battery again. 

Who Is ZMI

ZMI USA was founded by Dr. Yunpeng Pan (Brian) in 2016. Prior to starting the company, Brian worked as a professor teaching college mathematics and graduate-level operations research and data analytics courses at South Dakota State University. Brian holds MSc degrees in Computer Science and Operations Research and a PhD in Industrial Engineering from the University of Wisconsin-Madison. He began his career in the private sector and has many years of experience working in the communication device, e-commerce, and medical equipment development industries.

ZMI USA is an independent, forward-thinking company that seeks to bring pure, simple, and economical gadgets to the US market. We believe in saving money on unnecessary frills and flashy marketing, so we can pass on those savings to our customers. We spend most of our time and money improving the quality and reliability of our products and helping our customers. We only focus on two things: our products and our customers.

ZMI USA is backed by a generous investment from Zimi Corporation. Zimi Corporation is wholly owned by Xiaomi Inc and specializes in the design and manufacturing of backup battery packs, power adapters, and charging cables for cell phones, tablets, laptops, and other mobile/smart devices. ZMI USA's best-known product is the PowerPack 20K, which has been the Wirecutter's #1 choice among the Best USB Power Banks for Laptops since June 2018.
