Zendure USA Inc. was founded in 2013 by Tom Haflinger and Bryan Liu. Our mission is to deliver top-quality consumer electronics that exceed consumer expectations using high-end materials, premiere product development partners and user-centric design. Zendure’s first product was the A-Series External Battery, which was supported by over two thousand people in the one-month Kickstarter campaign, making it one of the most successful external batteries projects out there.
We strive to keep innovating, designing trustworthy products, and improving people’s lives. Take a look at how far we've come.
Watch our original Kickstarter video below.
Most lithium-ion batteries are capable of being charged and discharged about 500 times. This is sort of the "life expectancy" of the internal components. The primary job of the exterior is to protect the internal components over the life of the product. Using the world’s most advanced industrial design and molding techniques, our engineering team was able to build an external battery that has unprecedented durability, inside and out.
Zendure A-Series batteries are made from a durable composite material (Polycarbonate +ABS) that’s used in a vast array of other resilient products, including high-end suitcases, and the recent iPhone 5C. The exterior shell is reinforced by support ridges to resist warping. Between the front and back covers is a shock-resistant rubber belt (polycarbonate + TPU) to help protect the battery from drops.
While the car test certainly is flashy, numbers matter too. All three models were put through two hours of drop tests, falling repeatedly onto a hard cement surface from one meter. The three models also spent ten hours dancing around during a formal vibration test. Again, flying colors across the board. And the internal batteries have been vetted by their manufacturer after suffering several hours of impact tests by a 9kg hammer dropped from 60cm, as well as a ten-second encounter under a total weight of more than 1300kg.
Current owners of external batteries may already be aware that a battery’s rated capacity is not a clear indication of actual performance. Internal resistance takes some of the energy out of the system. The batteries themselves usually hold a charge at about 3.7 volts, while the devices that they power require 5 volts. This transformation takes energy out of the system, as do other circuit operations.
We achieve these results by employing a design that includes the best internal batteries, the best control chip and a passive cooling system that transfers heat away from the internal components. In addition, our batteries can go through over 500 full charge/discharge cycles over the life of the product.
The Zendure A-Series can charge other devices while it is being charged. So you don’t have to constantly rearrange your charging cables or plug in two wall chargers. Just leave everything plugged in, and let the A-Series take care of business.
The key to building a great product is to focus on the people who will be using it, so we started with consumer and market research. What do people look for when they’re deciding which battery to buy? What factors determine satisfaction with the product?
We also bought batteries from a variety of manufacturers and tried them out for ourselves.
Then we put together some focus groups and interviews to really get in touch with our consumers. We brought in current battery owners and also mobile phone users who were considering shopping for one. We asked them how they decided which products to buy, or how they were planning to begin their search. We showed them existing products as well as some experimental mock-up images and got their opinions on aesthetic value. It was a really great experience. Our participants gave us detailed answers to our questions and were really supportive in our quest to figure out how to make the best possible battery.
While founder Tom Haflinger conducted the interviews in the U.S., co-founder Bryan Liu started looking at potential manufacturers in China. We were looking for a facility with a lot of experience, a reputation for making quality products, and a high output volume. At the same time, we didn’t want some cold mega-corporation that would rarely return our emails.
Bryan found a great team in southern China with an incredible reputation. After meeting with the owner in person and touring the facility, we were convinced that these were the folks we wanted to work with.
We finally had a functional prototype that worked as well as the thing we imagined in our heads. Suddenly, it all felt so real.
The Zendure A-Series is uniquely great, and we built it just for you.
Bryan Liu is the Chief Executive Officer of Zendure, as well as the lead designer for the A-Series external battery. He came up with the basic structural and electronic concept of the A-Series and coordinated the launch of Zendure’s flagship product. He brought together the various engineering and manufacturing resources that were involved in the development process, and he constantly keeps in contact with all of us to make sure we’re sticking to our launch timeline.
Bryan’s lifelong fascination with electronics is due in part to his father, who was a self-taught electrical engineer. Bryan studied Information Technology in college. For the past decade, he has held senior marketing and product development roles in a number of reputable engineering and technology firms, including Halma, Ocean Optics, and a Siemens distributor in China.
Tom Haflinger is Zendure’s Chief Marketing Officer. His responsibilities include marketing, public relations and web development, as well as business administration. Tom conducted the consumer focus groups that helped us define our objectives. Tom’s parents both have a great deal of experience in electronics design and manufacturing, so Tom has always been fascinated with gadgets. He has worked in product development for Eastman Kodak, retail services for Apple and spent several years as a professional web developer and photographer.
The name "Zendure" is a combination of "Zen" and "endure". High-quality products endure a number of threats. Not just physical threats from accidents or rough storage, but also age. Quality products last a long time. The "Zen" prefix was chosen because it's a word that people often associate with a gentle nature. Our aesthetic designs are meant to communicate durability, but not in an aggressive way. Resilience, but not "military grade".
